==Introduction== <!--T:2-->
== Setup ==


<!--T:3-->
1. Open FreeCAD, create a new empty document, switch to the [[Arch Workbench]].
This tutorial shows how to place [[Arch_Window|Arch Windows]] and Doors in a building model, how to display them as open in the 3D view, and how to create a 2D drawing (plan and elevation projection) for the model. It uses the [[Draft_Workbench|Draft Workbench]], the [[Arch_Workbench|Arch Workbench]], and the [[TechDraw_Workbench|TechDraw Workbench]].


<!--T:4-->
2. Make sure your units are set correctly, {{MenuCommand|Edit → Preferences ... → General → Units}}. For example, <code>MKS(m/kg/s/degree)</code> is good for dealing with distances in a typical building; moreover, setting 4 decimals is good to consider even the smallest fractions of a meter.
Common tools used are: [[Draft_Snap_Grid|Draft Grid]], [[Draft_Snap|Draft Snap]], [[Draft_Wire|Draft Wire]], [[Arch_Wall|Arch Wall]], [[Arch_Window|Arch Window]], [[Arch_SectionPlane|Arch SectionPlane]], and [[TechDraw_ArchView|TechDraw ArchView]].


<!--T:80-->
3. Make sure you use [[Draft ToggleGrid]] to show a grid with enough resolution, You can change the grid properties if needed, {{MenuCommand|Edit → Preferences ... → Draft → Grid and snapping → Grid}}. For example, lines at every 50 mm, with major lines every 20 lines, and 1000 lines in total.
See also the following page for some videos on how to work with windows and doors.
* [http://help-freecad-jpg87.fr/04_arch_ind.php The workbench used to create architectural projects is called Arch]


== Setup == <!--T:5-->
4. Zoom out of the 3D view if you are too close to the grid.


<!--T:6-->
Create a simple building with closed walls, two doors and two windows.
1. Open FreeCAD, create a new empty document, and switch to the [[Arch_Workbench|Arch Workbench]].


<!--T:7-->
== Placing a wall ==
2. Make sure your units are set correctly in the menu {{MenuCommand|Edit → Preferences → General → Units}}. For example, {{incode|MKS (m/kg/s/degree)}} is good for dealing with distances in a typical building; moreover, set the number of decimals to {{incode|4}}, to consider even the smallest fractions of a meter.


<!--T:8-->
5. Use the [[Draft Wire]] tool to create a closed wire. Go counterclockwise.
3. Use the [[Draft_ToggleGrid|Draft ToggleGrid]] button to show a grid with enough resolution. You can change the grid appearance in the menu {{MenuCommand|Edit → Preferences → Draft → Grid and snapping → Grid}}. Set lines at every {{incode|50 mm}}, with major lines every {{incode|20}} lines (every meter), and {{incode|1000 lines}} in total (the grid covers an area of 50 m x 50 m).
:5.1. First point in (0, 0, 0); in the dialog enter {{KEY|0}} {{KEY|m}} {{KEY|ENTER}}, {{KEY|0}} {{KEY|m}} {{KEY|ENTER}}, {{KEY|0}} {{KEY|m}} {{KEY|ENTER}}
:5.2. Second point in (3, 0, 0). Press {{KEY|x}} to constrain the movement to the X axis; enter the value {{KEY|3}} {{KEY|m}} {{KEY|ENTER}}
:5.3. Third point in (3, 4, 0). Press {{KEY|y}} to constrain the movement to the Y axis; enter the value {{KEY|4}} {{KEY|m}} {{KEY|ENTER}}
:5.4. Fourth point in (0, 4, 0). Press {{KEY|x}} to constrain the movement to the X axis; enter the value {{KEY|-}} {{KEY|3}} {{KEY|m}} {{KEY|ENTER}}
:5.5. Press {{KEY|o}} to close the Wire, and close the tool.
:5.6. In the number pad press {{KEY|0}} to get an axonometric view of the model.
:5.7. The points can also be input with the mouse, selecting points in the grid, with the help of the [[Draft Snap]] toolbar, with the [[Draft Grid]] method.


<!--T:9-->
6. Select the <code>DWire</code> and change the property {{PropertyData|Make Face}} to {{FALSE}}
4. [[Std_ViewZoomOut|Zoom out]] of the 3D view if you are too close to the grid.


<!--T:10-->
7. Select the <code>DWire</code> and click the [[Arch Wall]] tool; the Wall is immediately created with a width (thickness) of 0.2 m, and height of 3 m.
Now we are ready to create a simple building with closed walls, two doors and two windows.


== Placing doors and windows ==
== Placing a wall == <!--T:11-->
8. Click the [[Arch Window]] tool, as preset select simple door, and change the height to 2 m
:8.1. Change the snapping to [[Draft Midpoint]], and try selecting the lower edge of the frontal wall; when the midpoint is active, click to place the door
:8.2. Click the [[Arch Window]] tool again, and place another door, but this time in the midpoint of the back wall; rotate the view if necessary


<!--T:12-->
9. Click the [[Arch Window]] tool, as preset select Open 1-pane, and change the still height to 1 m
5. Use the [[Draft_Wire|Draft Wire]] tool to create a closed wire. Go counterclockwise.
:9.1. Keep the snapping to [[Draft Midpoint]], and try selecting the lower edge of the left side wall; when the midpoint is active, click to place the window
:5.1. First point in (0, 0, 0); in the dialog enter {{KEY|0}} {{KEY|m}} {{KEY|Enter}}, {{KEY|0}} {{KEY|m}} {{KEY|Enter}}, {{KEY|0}} {{KEY|m}} {{KEY|Enter}}.
:5.2. Second point in (3, 0, 0). Press {{KEY|X}} to constrain the movement to the X axis; enter the value {{KEY|3}} {{KEY|m}} {{KEY|Enter}}.
:5.3. Third point in (3, 4, 0). Press {{KEY|Y}} to constrain the movement to the Y axis; enter the value {{KEY|4}} {{KEY|m}} {{KEY|Enter}}.
:5.4. Fourth point in (0, 4, 0). Press {{KEY|X}} to constrain the movement to the X axis; enter the value {{KEY|-}} {{KEY|3}} {{KEY|m}} {{KEY|Enter}}.
:5.5. Press {{KEY|O}} to close the Wire, and close the tool.
:5.6. In the number pad press {{KEY|0}} to get an [[Std_ViewIsometric|axonometric view]] of the model.
:{{Emphasis|Note:}} the points can also be defined with the mouse pointer by choosing intersections on the grid, with the help of the [[Draft_Snap|Draft Snap]] toolbar and the [[Draft_Snap_Grid|Draft Grid]] method.


<!--T:13-->
:Note: the still height is the distance from the floor to the lower edge of the element; for doors the still height is usually 0 m as doors are normally touching the floor; on the other hand, windows have a usual separation of 0.5 m to 1.5 m from the floor.
6. Select the {{incode|DWire}} and change the property {{PropertyData|Make Face}} to {{FALSE}}.


<!--T:14-->
:9.2. Click the [[Arch Window]] tool again, and place another window, but this time in the midpoint of the right wall; rotate the view if necessary. This time make the window's width (length) 1.5 m, and the still height 1 m
7. Select the {{incode|DWire}} and click the [[Arch_Wall|Arch Wall]] tool; the Wall is immediately created with a default width (thickness) of 0.2 m, and height of 3 m.
:{{Emphasis|Note:}} if the property {{PropertyData|Make Face}} of {{incode|DWire}} is {{TRUE}}, this step would create a solid block, instead of using only the contour of {{incode|DWire}}.


</translate>
:Note: when placing a windows or a door hover the element over the [[Arch Wall]], and wait for the element to rotate so that it is parallel to that wall. Use the [[Draft Near]] method from the [[Draft Snap]] toolbar to easily select a face of the wall; aim for the lower edge of the Wall, and use the still height to adjust the distance from the floor. Having many snapping options active may cause some issues with placing the element, so try with only one option at the time.

:Note 2: if the window or door was placed parallel to the [[Arch Wall]], but not exactly in the position that you want it, you can adjust the position of the underlying [[Sketcher Sketch]] from the Property view. For example, if you want to move the <code>Window001</code> a bit higher, select the underlying <code>Sketch004</code>, and change its position to <code>[3.1 m, 2.0 m, 1.8 m]</code>. The entire <code>Window001</code> should move up.

<!--T:18-->
10. Select <code>Sketch</code> underlying <code>Door</code>, and press {{KEY|SPACE}}, or change the property {{PropertyView|Visibility}} to {{TRUE}}.
8. Click the [[Arch_Window|Arch Window]] tool; as preset select {{incode|Simple door}}, and change the height to 2 m.
:8.1. Change the snapping to [[Draft_Snap_Midpoint|Draft Midpoint]], and try selecting the bottom edge of the frontal wall; rotate the [[Std_View_Menu|standard view]] as necessary to help you pick the edge and not the wall face; when the midpoint is active, click to place the door.
:8.2. Click the [[Arch_Window|Arch Window]] tool again, and place another door, but this time in the midpoint of the rear wall; rotate the [[Std_View_Menu|standard view]] as necessary.


</translate>
11. Double click <code>Door</code> in the tree view to start editing
[[Image:03_T01_wall_place_door_rear.png|600px|center]]
<translate>
<!--T:19-->
{{Caption|align=center|Snapping to the midpoint of the bottom edge of the wall to place the door}}


<!--T:20-->
:11.1. Inside the <code>Window elements</code> frame there are two panes, <code>Wires</code> and <code>Components</code>.
9. Click the [[Arch_Window|Arch Window]] tool; as preset select {{incode|Open 1-pane}}, and change the {{incode|Sill height}} to 1 m.
:9.1. Keep the snapping to [[Draft_Snap_Midpoint|Draft Midpoint]], and try selecting the lower edge of the left side wall; rotate the [[Std_View_Menu|standard view]] as necessary to help you pick the edge and not the wall face; when the midpoint is active, click to place the window.


<!--T:21-->
:Note: with a simple door preset there are two wires, <code>Wire0</code> and <code>Wire1</code>, and two components, <code>OuterFrame</code> and <code>Door</code>. With a custom designed [[Arch Door]], there may be more wires and components.
:{{Emphasis|Note:}} the {{incode|Sill height}} is the distance from the floor to the lower edge of the element. For doors the {{incode|Sill height}} is usually 0 m as doors are normally touching the floor; on the other hand, windows have a usual separation of 0.5 m to 1.5 m from the floor.


<!--T:22-->
:11.2. Click on <code>Door</code>, and click the '''{{KEY|Edit}}''' button. This shows the properties of the <code>Door</code> component like <code>Name</code>, <code>Type</code>, <code>Wires</code>, <code>Thickness</code>, <code>Offset</code>, <code>Hinge</code>, and <code>Opening mode</code>.
:9.2. Click the [[Arch_Window|Arch Window]] tool again, and place another window, but this time in the midpoint of the right wall; rotate the [[Std_View_Menu|standard view]] as necessary. This time make the window's width (length) 1.5 m, and again make the {{incode|Sill height}} 1 m.


</translate>
:11.3. In the 3D view, select only one vertical edge in the visible Sketch of the Door, then click the '''{{KEY|Get selected edge}}''' button. The button should change to an edge name, for example, '''{{KEY|Edge8}}'''.

{{Caption|align=center|Snapping to the midpoint of the bottom edge of the wall to place the window}}


<!--T:24-->
:11.4. Change the <code>Opening mode</code> to <code>Arc 90</code>, or any other option.
:{{Emphasis|Note:}} the {{incode|Sill height}} parameter can only be set when initially creating the window with a preset. Once the window is inserted, modify its placement by editing the {{PropertyData|Position}} vector {{incode|[x, y, z]}} of the underlying [[Sketcher_Workbench|Sketcher Sketch]].


<!--T:25-->
:11.5. Click the '''{{KEY|+Create/update component}}''' button, and then the '''{{KEY|Close}}''' button to finish editing the Door. The Sketch may become hidden again.
:9.3. Move the {{incode|Window001}} a bit higher. Select the underlying {{incode|Sketch003}}, and change its {{PropertyData|Position}} from {{incode|[3.1 m, 2.0 m, 1.0 m]}} to {{incode|[3.1 m, 2.0 m, 1.6 m]}}. The entire {{incode|Window001}} should move up. The wall may still show an opening in the previous position; if this happens, right click the {{incode|Wall}} element, select {{incode|Mark to recompute}}, and then press {{KEY|Ctrl}}+{{KEY|R}} to [[recompute]] the model.


</translate>
12. Select <code>Door</code>, and give the property {{PropertyData|Opening}} a value of 45. The solid panel of the door should open to the inside of the building.
[[Image:04.1_T01_wall_built.png|600px|center]]
<translate>
<!--T:26-->
{{Caption|align=center|Wall built with doors and windows}}


<!--T:27-->
13. Select <code>Door</code>, and change the property {{PropertyData|Symbol Elevation}} to {{TRUE}}; a wire starting from the door frame should indicate where the door opens, if the door is viewed from the front; change the property {{PropertyData|Symbol Plan}} to {{TRUE}}; a circular arc should indicate how the door opens, if the door is viewed from the top.
{{Emphasis|Note:}} when placing a window or a door with a preset, hover the element over the [[Arch_Wall|Arch Wall]], and wait for the element to rotate so that it is parallel to that wall. Aim for the bottom edge of the wall, and use the {{incode|Sill height}} to adjust the distance from the floor. If this is difficult, use the [[Draft_Snap_Near|Draft Near]] snapping mode of the [[Draft_Snap|Draft Snap]] toolbar to insert the element anywhere on the face of the wall, and then adjust its {{PropertyData|Position}} manually as described above. Having many [[Draft_Snap|Draft Snap]] modes active at the same time may cause issues with placing the element, so try with only one option at a time.


<!--T:28-->
14. Repeat the steps with <code>Door001</code> and the underlying <code>Sketch002</code> to make it open 75 degrees. Also show the elevation and plan symbols.
{{Emphasis|Note 2:}} occasionally the window may be placed outside the [[Arch_Wall|Arch Wall]]; as long as the element is parallel to that wall, you should be able to correct the position manually.


== Opening the windows ==
== Opening the doors == <!--T:29-->
15. Double click the <code>Window</code> in the tree view to start editing


<!--T:30-->
:15.1. Click on the <code>InnerFrame</code> component, and click the '''{{KEY|Edit}}''' button.
10. In the tree view select {{incode|Sketch}} underlying {{incode|Door}}, and press {{KEY|Space}}, or change the property {{PropertyView|Visibility}} to {{TRUE}}


<!--T:31-->
:15.2. In the 3D view, select only one vertical edge of the <code>InnerFrame<c/ode>. The <code>OuterFrame</code> and the <code>InnerFrame</code> are very close to each other, so zoom in as close as possible to the visible Sketch of the Window to select the appropriate wire; also try using [[Std View Menu|Wireframe mode]] to remove the solid Wall, and see only the wires. then click the '''{{KEY|Get selected edge}}''' button. The button should change to an edge name, for example, '''{{KEY|Edge12}}'''.
11. Double click {{incode|Door}} in the tree view to start editing it.


<!--T:32-->
:15.3. Change the <code>Opening mode</code> to <code>Arc 90 inv</code>, or any other option.
:11.1. Inside the {{incode|Window elements}} frame there are two panes, {{incode|Wires}} and {{incode|Components}}.
:{{Emphasis|Note:}} with a simple door preset there are two wires, {{incode|Wire0}} and {{incode|Wire1}}, and two components, {{incode|OuterFrame}} and {{incode|Door}}. A custom designed [[Arch_Door|Arch Door]] may have more wires and components.


<!--T:33-->
:15.4. Select <code>Window</code>, and give the property {{PropertyData|Opening}} a value of 45. The inner frame containing the transparent glass should open to the inside of the building.
:11.2. Click on {{incode|Door}}, and click the {{Button|Edit}} button. This shows the properties of the {{incode|Door}} component like {{incode|Name}}, {{incode|Type}}, {{incode|Wires}}, {{incode|Thickness}}, {{incode|Offset}}, {{incode|Hinge}}, and {{incode|Opening mode}}.
:11.3. In the 3D view, select only one vertical edge in the visible sketch of the door, then click the {{Button|Get selected edge}} button. The button should change to an edge name, for example, {{Button|Edge8}}.
:11.4. Change the {{incode|Opening mode}} to {{Button|Arc 90}}, or any other option.
:11.5. Click the {{Button|+Create/update component}} button, and then {{Button|Close}} to finish editing the door. The sketch may become hidden again.


<!--T:34-->
:15.5. Select <code>Window</code>, and change the property {{PropertyData|Symbol Elevation}} to {{TRUE}}; a wire starting from the window frame should indicate where the inner frame opens, if the window is viewed from the front; change the property {{PropertyData|Symbol Plan}} to {{TRUE}}; a circular arc should indicate how the inner frame opens, if the window is viewed from the top.
[[Image:05_T01_window_edit.png|center]]
{{Caption|align=center|Dialog to edit a window or a door}}


<!--T:35-->
16. Repeat the steps with <code>Window001</code> and the underlying <code>Sketch004</code> to make it open 75 degrees. Also show the elevation and plan symbols. In this case, don't pick a vertical wire of the <code>InnerFrame</code> but pick the top horizontal wire.

17. In the tree view, select all components, the [[Arch Wall]], the two [[Arch Window]]s, and the two [[Arch Door]]s, then use the [[Arch SectionPlane]] tool to create a <code>Section</code> element.
<translate>
<!--T:36-->
{{Caption|align=center|Vertical edge of sketch selected as hinge for a door}}


<!--T:37-->
18. Change to [[TechDraw Workbench]] and insert a new page with the [[TechDraw New Default]] tool; a new <code>Page</code> object is created, and the view switches to this page. The page inserted is a standard A4 sheet in landscape orientation, with a basic frame around it. Use the [[TechDraw New Pick]] tool if you need to create a new page using a particular SVG template.
12. Select {{incode|Door}}, and give the property {{PropertyData|Opening}} a value of 45. The solid panel of the door should open to the inside of the building.


<!--T:38-->
19. Select <code>Section</code>, and use the [[TechDraw NewArch]] tool to create an <code>ArchView</code> object in the page. Most probably the new object won't be visible in the page because it has a very large scale of 1, that is, 1:1.
13. Select {{incode|Door}}, and change the property {{PropertyData|Symbol Elevation}} to {{TRUE}}; the tip of the created wire indicates which side of the door opens; this is easier to see if the viewport changes to [[Std_ViewFront|front view]]. Change the property {{PropertyData|Symbol Plan}} to {{TRUE}}; a circular arc should indicate the extent of the door's swing; this is easier to see if the viewport changes to [[Std_ViewTop|top view]].


<!--T:39-->
20. Select this <code>ArchView</code> object, and change the property {{PropertyData|Scale}} to 0.02, which is equivalent to 1:50, a scale suitable for typical buildings. The object should appear in the center of the page, and can be moved to a better position on the page. The two doors should look like they are open, but only the left window looks open; the reason for this is that the [[Arch SectionPlane]] is not high enough to cut through the right window, as can be seen from the 3D view.
14. Repeat the steps with {{incode|Door001}} and the underlying {{incode|Sketch001}} to make the door open 75 degrees to the inside of the building. Also enable the elevation and plan symbols.


<!--T:40-->
21. Select the <code>Section</code> element, place it higher over the floor, by changing the property {{PropertyData|Position}} to <code>[1.5 m, 2.0 m, 1.9 m]</code>. Now it barely touches all elements. The updated view in the TechDraw page now shows all openings in the [[Arch Wall]] produced by the doors and windows.

</translate>
22. Go back to the [[Arch Workbench]]. In the tree view, select all components, the [[Arch Wall]], the two [[Arch Window]]s, and the two [[Arch Door]]s, then use the [[Arch SectionPlane]] tool to create a second <code>Section001</code> element.
[[Image:09_T01_window_symbol_plan.png|600px|center]]
<translate>
<!--T:42-->
{{Caption|align=center|Door with plan symbol, top view}}


== Opening the windows == <!--T:43-->
:22.1. Rotate the second <code>Section001</code>, so that it cuts vertically through the building. Change the properties {{PropertyData|Axis}} to <code>[1, 0, 0]</code>, and {{PropertyData|Angle}} to <code>90</code>.


<!--T:44-->
:22.2. Create one more plane <code>Section002</code>, and position it vertically in front of the building. Change the properties {{PropertyData|Axis}} to <code>[1, 0, 0]</code>, {{PropertyData|Angle}} to <code>90</code>, and {{PropertyData|Position}} to <code>[1.5, -1, 1.5]</code>.
15. In the tree view select {{incode|Sketch002}} underlying {{incode|Window}}, and press {{KEY|Space}}, or change the property {{PropertyView|Visibility}} to {{TRUE}}.


<!--T:45-->
:Note: you can adjust the arrow size of the planes {{PropertyView|Arrow Size}} to 200 mm, to quickly recognize to which side the planes are pointing.
16. Double click {{incode|Window}} in the tree view to start editing it.


<!--T:46-->
23. Go back to the [[TechDraw Workbench]], and the Page, and use the [[TechDraw NewArch]] tool on each of the <code>Section001</code> and <code>Section002</code> planes. Use the same scale of 1:50. Rotate each of the resulting ArchViews by -90 degrees, to correct the appearance of the projections.
:16.1. Click on the {{incode|InnerFrame}} component, and click the {{Button|Edit}} button.

<!--T:47-->
:16.2. In the 3D view, select only one vertical edge of {{incode|Sketch002}}. The wires representing {{incode|OuterFrame}} and the {{incode|InnerFrame}} are very close to each other, so [[Std_ViewZoomIn|zoom in]] as close as possible to the sketch to select the appropriate wire. Then click the {{Button|Get selected edge}} button. The button should change to an edge name, for example, {{Button|Edge12}}.
:{{Emphasis|Note:}} when there are many solids on the screen that it becomes difficult to select only one edge, switch to [[Std_DrawStyle#Wireframe|wireframe mode]] to remove the faces of those solid objects, and see only the wires, edges, and contours.

<!--T:48-->
:16.3. Change the {{incode|Opening mode}} to {{incode|Arc 90 inv}}, or any other option.

<!--T:49-->
17. Select {{incode|Window}}, and give the property {{PropertyData|Opening}} a value of 45. The inner frame containing the transparent glass should open to the inside of the building.

<!--T:50-->
18. Select {{incode|Window}}, and change the property {{PropertyData|Symbol Elevation}} to {{TRUE}}; the tip of the created wire indicates which side of the window opens; this is easier to see if the viewport changes to [[Std_ViewLeft|left side view]]. Change the property {{PropertyData|Symbol Plan}} to {{TRUE}}; a circular arc should indicate the extent of the window's swing; this is easier to see if the viewport changes to [[Std_ViewTop|top view]].

<!--T:51-->
19. Repeat the steps with {{incode|Window001}} and the underlying {{incode|Sketch003}} to make the window open 75 degrees. Also show the elevation and plan symbols. In this case, don't pick a vertical wire of the {{incode|InnerFrame}} as hinge, but pick the top horizontal wire. This means that this window will open differently from the other window. The elevation symbol will be better seen from a [[right side view]]. The plan symbol will be better seen from the [[Std_ViewFront|front view]]; however, since the wall is obstructing the view, you can change its {{PropertyView|Transparency}} to a value such as 85 to see through it; alternatively you can also change its {{PropertyView|Display Mode}} to {{incode|Wireframe}} to show only its edges.

20. Still in the [[Arch_Workbench|Arch Workbench]], select all components in the tree view, the [[Arch_Wall|Arch Wall]], the two [[Arch_Window|Arch Window]]s, and the two [[Arch_Door|Arch Door]]s, then use the [[Arch_SectionPlane|Arch SectionPlane]] tool to create a {{incode|Section}} element.

<!--T:57-->
{{Emphasis|Note:}} change the property {{PropertyData|Arrow size}} of the section plane to a larger value, for example, {{incode|200 mm}}, so that the direction of the section is clearly visible in the 3D viewport.

<!--T:59-->
21. Change to the [[TechDraw_Workbench|TechDraw Workbench]] and insert a new page with the [[TechDraw_PageDefault|TechDraw PageDefault]] tool; a new {{incode|Page}} object is created, and the view switches to this page. The page inserted is a standard A4 sheet in landscape orientation, with a basic frame around it. Use the [[TechDraw_PageTemplate|TechDraw PageTemplate]] tool if you need to create a new page using a particular [[SVG]] template.

<!--T:60-->
22. Select {{incode|Section}}, and use the [[TechDraw_ArchView|TechDraw ArchView]] tool to create an {{incode|ArchView}} object in the page. Most probably the new object won't be visible in the page because it has a very large scale of {{incode|1}}, that is, 1:1. This means that every meter in the 3D view is shown as a meter in the page view; since the page is only 0.297 m x 0.210 m in size, most features are too big to fit in this page at their natural scale.

<!--T:61-->
23. Select this {{incode|ArchView}} object, and change the property {{PropertyData|Scale}} to {{incode|0.02}}, which is equivalent to 1:50, a scale suitable for typical buildings. This means every meter in the 3D view will be shown as 20 mm in the page. The object should appear in the center of the page, and can be moved to a better position on the left side. The two doors should look like they are open, but only the left window should look open. The reason the right window doesn't appear in the projection is that the plane defined by {{incode|Section}} does not cut through this right window.

Introduction

This tutorial shows how to place Arch Windows and Doors in a building model, how to display them as open in the 3D view, and how to create a 2D drawing (plan and elevation projection) for the model. It uses the Draft Workbench, the Arch Workbench, and the TechDraw Workbench.

Common tools used are: Draft Grid, Draft Snap, Draft Wire, Arch Wall, Arch Window, Arch SectionPlane, and TechDraw ArchView.

See also the following page for some videos on how to work with windows and doors.

Setup

1. Open FreeCAD, create a new empty document, and switch to the Arch Workbench.

2. Make sure your units are set correctly in the menu Edit → Preferences → General → Units. For example, MKS (m/kg/s/degree) is good for dealing with distances in a typical building; moreover, set the number of decimals to 4, to consider even the smallest fractions of a meter.

3. Use the Draft ToggleGrid button to show a grid with enough resolution. You can change the grid appearance in the menu Edit → Preferences → Draft → Grid and snapping → Grid. Set lines at every 50 mm, with major lines every 20 lines (every meter), and 1000 lines in total (the grid covers an area of 50 m x 50 m).

4. Zoom out of the 3D view if you are too close to the grid.

Now we are ready to create a simple building with closed walls, two doors and two windows.

Placing a wall

5. Use the Draft Wire tool to create a closed wire. Go counterclockwise.

5.1. First point in (0, 0, 0); in the dialog enter 0 m Enter, 0 m Enter, 0 m Enter.
5.2. Second point in (3, 0, 0). Press X to constrain the movement to the X axis; enter the value 3 m Enter.
5.3. Third point in (3, 4, 0). Press Y to constrain the movement to the Y axis; enter the value 4 m Enter.
5.4. Fourth point in (0, 4, 0). Press X to constrain the movement to the X axis; enter the value - 3 m Enter.
5.5. Press O to close the Wire, and close the tool.
5.6. In the number pad press 0 to get an axonometric view of the model.
Note: the points can also be defined with the mouse pointer by choosing intersections on the grid, with the help of the Draft Snap toolbar and the Draft Grid method.

6. Select the DWire and change the property DataMake Face to false.

7. Select the DWire and click the Arch Wall tool; the Wall is immediately created with a default width (thickness) of 0.2 m, and height of 3 m.

Note: if the property DataMake Face of DWire is true, this step would create a solid block, instead of using only the contour of DWire.

Placing doors and windows

8. Click the Arch Window tool; as preset select Simple door, and change the height to 2 m.

8.1. Change the snapping to Draft Midpoint, and try selecting the bottom edge of the frontal wall; rotate the standard view as necessary to help you pick the edge and not the wall face; when the midpoint is active, click to place the door.
8.2. Click the Arch Window tool again, and place another door, but this time in the midpoint of the rear wall; rotate the standard view as necessary.

Snapping to the midpoint of the bottom edge of the wall to place the door

9. Click the Arch Window tool; as preset select Open 1-pane, and change the Sill height to 1 m.

9.1. Keep the snapping to Draft Midpoint, and try selecting the lower edge of the left side wall; rotate the standard view as necessary to help you pick the edge and not the wall face; when the midpoint is active, click to place the window.
Note: the Sill height is the distance from the floor to the lower edge of the element. For doors the Sill height is usually 0 m as doors are normally touching the floor; on the other hand, windows have a usual separation of 0.5 m to 1.5 m from the floor.
9.2. Click the Arch Window tool again, and place another window, but this time in the midpoint of the right wall; rotate the standard view as necessary. This time make the window's width (length) 1.5 m, and again make the Sill height 1 m.

Snapping to the midpoint of the bottom edge of the wall to place the window

Note: the Sill height parameter can only be set when initially creating the window with a preset. Once the window is inserted, modify its placement by editing the DataPosition vector [x, y, z] of the underlying Sketcher Sketch.
9.3. Move the Window001 a bit higher. Select the underlying Sketch003, and change its DataPosition from [3.1 m, 2.0 m, 1.0 m] to [3.1 m, 2.0 m, 1.6 m]. The entire Window001 should move up. The wall may still show an opening in the previous position; if this happens, right click the Wall element, select Mark to recompute, and then press Ctrl+R to recompute the model.

Wall built with doors and windows

Note: when placing a window or a door with a preset, hover the element over the Arch Wall, and wait for the element to rotate so that it is parallel to that wall. Aim for the bottom edge of the wall, and use the Sill height to adjust the distance from the floor. If this is difficult, use the Draft Near snapping mode of the Draft Snap toolbar to insert the element anywhere on the face of the wall, and then adjust its DataPosition manually as described above. Having many Draft Snap modes active at the same time may cause issues with placing the element, so try with only one option at a time.

Note 2: occasionally the window may be placed outside the Arch Wall; as long as the element is parallel to that wall, you should be able to correct the position manually.

Opening the doors

10. In the tree view select Sketch underlying Door, and press Space, or change the property ViewVisibility to true

11. Double click Door in the tree view to start editing it.

11.1. Inside the Window elements frame there are two panes, Wires and Components.
Note: with a simple door preset there are two wires, Wire0 and Wire1, and two components, OuterFrame and Door. A custom designed Arch Door may have more wires and components.
11.2. Click on Door, and click the Edit button. This shows the properties of the Door component like Name, Type, Wires, Thickness, Offset, Hinge, and Opening mode.
11.3. In the 3D view, select only one vertical edge in the visible sketch of the door, then click the Get selected edge button. The button should change to an edge name, for example, Edge8.
11.4. Change the Opening mode to Arc 90, or any other option.
11.5. Click the +Create/update component button, and then Close to finish editing the door. The sketch may become hidden again.

12. Select Door, and give the property DataOpening a value of 45. The solid panel of the door should open to the inside of the building.

13. Select Door, and change the property DataSymbol Elevation to true; the tip of the created wire indicates which side of the door opens; this is easier to see if the viewport changes to front view. Change the property DataSymbol Plan to true; a circular arc should indicate the extent of the door's swing; this is easier to see if the viewport changes to top view.

14. Repeat the steps with Door001 and the underlying Sketch001 to make the door open 75 degrees to the inside of the building. Also enable the elevation and plan symbols.

Opening the windows

15. In the tree view select Sketch002 underlying Window, and press Space, or change the property ViewVisibility to true.

16. Double click Window in the tree view to start editing it.

16.1. Click on the InnerFrame component, and click the Edit button.
16.2. In the 3D view, select only one vertical edge of Sketch002. The wires representing OuterFrame and the InnerFrame are very close to each other, so zoom in as close as possible to the sketch to select the appropriate wire. Then click the Get selected edge button. The button should change to an edge name, for example, Edge12.
Note: when there are many solids on the screen that it becomes difficult to select only one edge, switch to wireframe mode to remove the faces of those solid objects, and see only the wires, edges, and contours.
16.3. Change the Opening mode to Arc 90 inv, or any other option.

17. Select Window, and give the property DataOpening a value of 45. The inner frame containing the transparent glass should open to the inside of the building.

18. Select Window, and change the property DataSymbol Elevation to true; the tip of the created wire indicates which side of the window opens; this is easier to see if the viewport changes to left side view. Change the property DataSymbol Plan to true; a circular arc should indicate the extent of the window's swing; this is easier to see if the viewport changes to top view.

19. Repeat the steps with Window001 and the underlying Sketch003 to make the window open 75 degrees. Also show the elevation and plan symbols. In this case, don't pick a vertical wire of the InnerFrame as hinge, but pick the top horizontal wire. This means that this window will open differently from the other window. The elevation symbol will be better seen from a right side view. The plan symbol will be better seen from the front view; however, since the wall is obstructing the view, you can change its ViewTransparency to a value such as 85 to see through it; alternatively you can also change its ViewDisplay Mode to Wireframe to show only its edges.

20. Still in the Arch Workbench, select all components in the tree view, the Arch Wall, the two Arch Windows, and the two Arch Doors, then use the Arch SectionPlane tool to create a Section element.

Note: change the property DataArrow size of the section plane to a larger value, for example, 200 mm, so that the direction of the section is clearly visible in the 3D viewport.

21. Change to the TechDraw Workbench and insert a new page with the TechDraw PageDefault tool; a new Page object is created, and the view switches to this page. The page inserted is a standard A4 sheet in landscape orientation, with a basic frame around it. Use the TechDraw PageTemplate tool if you need to create a new page using a particular SVG template.

22. Select Section, and use the TechDraw ArchView tool to create an ArchView object in the page. Most probably the new object won't be visible in the page because it has a very large scale of 1, that is, 1:1. This means that every meter in the 3D view is shown as a meter in the page view; since the page is only 0.297 m x 0.210 m in size, most features are too big to fit in this page at their natural scale.

23. Select this ArchView object, and change the property DataScale to 0.02, which is equivalent to 1:50, a scale suitable for typical buildings. This means every meter in the 3D view will be shown as 20 mm in the page. The object should appear in the center of the page, and can be moved to a better position on the left side. The two doors should look like they are open, but only the left window should look open. The reason the right window doesn't appear in the projection is that the plane defined by Section does not cut through this right window.

24. Switch back to the Arch Workbench. In the tree view select all components again, and use the Arch SectionPlane tool to create a second Section001 element.

24.1. Select Section001 and change the property DataPosition to [1.5 m, 2.0 m, 1.8 m]. This second plane does cut through all Arch objects.
24.2. Switch back to the TechDraw Workbench. Select Section001, use the TechDraw ArchView tool to create ArchView001, and set DataScale to 0.02. The new view in the TechDraw page now shows all openings in the Arch Wall produced by doors and windows.

Note: set DataAll On to true for TechDraw ArchView objects so that all elements cut by the plane are visible in the page, regardless of their visibility state in the 3D viewport. The option DataShow Fill can also be set to true to draw a shade on the solids that were cut by the section plane.

25. Go back to the Arch Workbench. In the tree view, select all components, the Arch Wall, the two Arch Windows, and the two Arch Doors, then use the Arch SectionPlane tool to create a third Section002 element.

25.1. Rotate Section002, so that it cuts vertically through the building. Change the properties DataAxis to [1, 0, 0], and DataAngle to 90.
25.2. Change the DataPosition to [1.5 m, -1 m, 1.5 m], so that the plane is in front of the building.

26. Go back to the TechDraw Workbench, and use the TechDraw ArchView tool on Section002; remember to adjust the scale to 0.02 (1:50). Change DataRotation to -90 to correct the appearance of the projections. Arrange ArchView002 next to the other views in the page. This third projection looks at the building from the front.

Arch and TechDraw interaction

As of the time of writing of this document (FreeCAD 0.18, November 2018), the TechDraw Workbench can only display in its pages what the Arch Workbench exports as SVG. This means that the appearance of the elements included within the Arch SectionPlane tool, and displayed by the TechDraw ArchView tool, is controlled by the Arch Workbench.

The TechDraw Workbench only has minimal control over how it displays those Arch SectionPlane (ArchView) objects. Therefore, bug reports and feature requests related to displaying Arch elements should be filed with both workbenches.

A closer interaction between the workbenches is planed for future versions of FreeCAD. In those versions it is expected that long-standing issues be resolved, such as controlling the characteristics of lines and faces (line width, line color, face color, hatch patterns, and others).
