==Beschreibung== |

Der Befehl [[Image:Draft_Shape2DView.svg|24px]] '''Draft Form2DAnsicht''' erstellt 2D-Projektionen von ausgewählten Objekten, in der Regel 3D-Festkörper oder [[Arch_SectionPlane/de|Arch Schnittebenen]]. Die Projektionen werden in der [[3D_view/de|3D-Ansicht]] dargestellt. |
|||
The {{Button|[[Image:Draft Shape2DView.svg|16px]] [[Draft Shape2DView|Draft Shape2DView]]}} tool produces a 2D projection from a selected 3D solid object such as those created with the {{KEY|[[Image:Workbench_Part.svg|16px]] [[Part Workbench|Part]]}}, {{KEY|[[Image:Workbench_PartDesign.svg|16px]][[PartDesign Workbench|PartDesign]]}}, and {{KEY|[[Image:Workbench_Arch.svg|16px]] [[Arch Workbench|Arch]]}} Workbenches. |
|||
Draft Shape2DView projections can be displayed on a [[TechDraw_Workbench|TechDraw Workbench]] page using the [[TechDraw_DraftView|TechDraw DraftView]] command. Alternatively the [[TechDraw_Workbench|TechDraw Workbench]] offer its own projection commands. But these create projections that are only displayed on the drawing page and not in the [[3D_view|3D view]]. |

||
==Anwendung== |
|||
# |
# Optionally rotate the [[3D_view|3D view]]. The camera direction in the [[3D_view|3D view]] determines the projection vector. For example, a [[Std_ViewTop|top view]] will project onto the XY plane. The projection vector is ignored for projections created from [[Arch_SectionPlane|Arch SectionPlanes]]. |
||
# Optionally select one or more objects. |
|||
# Select a 3D object. |
|||
# There are several ways to invoke the command: |
|||
# Press the {{Button|[[Image:Draft Shape2DView.svg|16px]] [[Draft Shape2DView|Draft Shape2DView]]}} button. If no object is selected, you will be invited to select one. |
|||
#* Press the {{Button|[[Image:Draft_Shape2DView.svg|16px]] [[Draft_Shape2DView|Shape 2D view]]}} button. |
|||
#* Select the {{MenuCommand|Modification → [[Image:Draft_Shape2DView.svg|16px]] Shape 2D view}} option from the menu. |
|||
# If you have not yet selected an object: select an object in the [[3D_view|3D view]]. |
|||
# The projected objects are created on the XY plane. |
|||
==How to produce plans and sections with different linewidths== |
|||
The projected object will be created below the selected object, lying on the XY plane. It's position can be changed by changing its properties. The projection direction can also be changed after creation with the [[property editor]]. |
|||
[[Image:Draft_shape2dview_example_plan.png|700px]] |
|||
'''Note:''' If the selected object is an {{Button|[[Image:Arch SectionPlane.svg|16px]] [[Arch SectionPlane|Arch SectionPlane]]}}, the projection will use the contents and direction of that Section plane; in this case, the "Projection" property will be ignored. |
|||
Drawings with different linewidths for viewed and cut lines can easily be produced by using two shape2Dview objects from a same [[Arch_SectionPlane|Arch SectionPlane]]. One of the shape2Dview objects has its projection mode set to '''Solid''', which renders the viewed lines, and another set to '''Cut lines''' or '''Cut faces''' to render the cut lines. The two shape2Dviews are then placed at the same location, one on top of the other. |
|||
==Options== |
|||
<span id="Properties"></span> |

There are no options for this tool. Either it works with the selected object or not. |

==Properties== |
|||
Ein Draft Shape2DView-Objekt wird von einem [[Part_Part2DObject/de|Part Part2DObject]] abgeleitet und erbt alle seine Eigenschaften. Außerdem hat es die folgenden zusätzlichen Eigenschaften: |
|||
* {{PropertyData|Projection}}: specifies the direction of the projection as a vector. For example, (0,0,1) is a projection looking through the Z axis, which would be projected on the XY plane; (1,0,0) is a projection looking through the X axis, which would be projected on the YZ plane; (0,1,0) is a projection looking through the Y axis, which would be projected on the XZ plane. The values can also be negative, in which case the direction of projection is inverted. |
|||
* {{PropertyData|Projection Mode}}: it can be "Solid", "Individual Faces", "Cutlines", and "Cutfaces". |
|||
** The default projection is "Solid", which projects the entire selected shape. |
|||
** If only some faces of the base object are selected, the "Individual Faces" mode will project only those faces. |
|||
** If the selected object is an [[Arch SectionPlane]], the "Cutlines" mode will project only the edges being cut by the section plane. |
|||
** If the selected object is an [[Arch SectionPlane]], the "Cutfaces" mode will display the cut areas of solids as faces. |
|||
* {{PropertyData|In Place}}: if it is {{TRUE}}, together with "Cutlines" or "Cutfaces" modes, the resulting projection will appear co-planar with the [[Arch SectionPlane]]. {{Version|0.17}} |
|||
* {{PropertyData|HiddenLines}}: if it is {{TRUE}} it will show the hidden lines of the projection. |
|||
* {{PropertyData|Tessellation}}: if it is {{TRUE}} it will perform tessellation of ellipses and splines, that is, it will represent curves with very fine line segments. |
|||
:{{Emphasis|Note:}} this may be computationally intensive if {{PropertyData|Segment Length}} is very small. |
|||
* {{PropertyData|Segment Length}}: specifies the size in millimeters of linear segments if {{PropertyData|Tessellation}} is {{TRUE}}. |
|||
:{{Emphasis|Note:}} set a larger value first, and then change it to a smaller value to get better resolution. |
|||
* {{PropertyData|Visible Only}}: if it is {{TRUE}} the projection will be recomputed only if it is visible. |

|||
{{TitleProperty|Draft}} |
|||
The Draft Shape2DView tool can be used in [[macros]] and from the [[Python]] console by using the following function: |
|||
* {{PropertyData|Auto Update|Bool}}: specifies if the projection should be automatically recomputed if the {{PropertyData|Base}} object changes. Selecting {{False}} can be useful if there are many Draft Shape2DViews in a document or if they are complex. If set to {{False}} the [[Std_Refresh|Std Refresh]] command must be used to update the projection. {{Version|0.20}} |
|||
* {{PropertyData|Base|Link}}: specifies the object to be projected. |
|||
* {{PropertyData|Face Numbers|IntegerList}}: specifies the indices of the faces to be projected. Only works if {{PropertyData|Projection Mode}} is {{Value|Individual Faces}}. |
|||
* {{PropertyData|Fuse Arch|Bool}}: specifies if [[Arch Workbench|Arch objects]] of the same type and material are fused or not. |
|||
* {{PropertyData|Hidden Lines|Bool}}: specifies if hidden lines are shown or not. |
|||
* {{PropertyData|In Place|Bool}}: only works if the selected object is an [[Arch_SectionPlane|Arch SectionPlane]], and {{PropertyData|Projection Mode}} is {{Value|Cutlines}} or {{Value|Cutfaces}}, specifies if the projection will appear co-planar with the section plane. |
|||
* {{PropertyData|Projection|Vector}}: specifies the direction of the projection. Ignored if {{PropertyData|Base}} is an [[Arch_SectionPlane|Arch SectionPlane]]. |
|||
* {{PropertyData|Projection Mode|Enumeration}}: specifies the projection mode. The following modes are available: |
|||
** {{Value|Solid}}: projects the entire selected object. |
|||
** {{Value|Individual Faces}}: only projects the faces in the {{PropertyData|Face Numbers}} list. |
|||
** {{Value|Cutlines}}: only works if the selected object is an [[Arch_SectionPlane|Arch SectionPlane]], projects only the edges cut by the section plane. |
|||
** {{Value|Cutfaces}}: only works if the selected object is an [[Arch_SectionPlane|Arch SectionPlane]], projects the areas cut through solids by the section plane as faces. |
|||
** {{Value|Solid faces}}: projects the entire selected object by cutting faces one by one. Can be used if the {{Value|Solid}} mode gives wrong results. {{Version|0.20}} |
|||
* {{PropertyData|Segment Length|Float}}: specifies the size in millimeters of linear segments if {{PropertyData|Tessellation}} is {{TRUE}}. |
|||
* {{PropertyData|Tessellation|Bool}}: specifies if tessellation should be performed. Tessellation means that curves are replaced by sequences of line segments. This can be computationally intensive if the {{PropertyData|Segment Length}} is too short. |
|||
* {{PropertyData|Visible Only|Bool}}: specifies if the projection should only be recomputed if it is visible. |
|||
* {{PropertyData|Exclusion Points|Vector list}}: A list of exclusion points. Any edge passing through any of those points will not be drawn. {{Version|0.20}} |
|||
* {{PropertyData|Exclusion Names|String list}}: A list of object names. Any viewed or cut child object with a name in that list will not be drawn. {{Version|0.21}} |

Beschreibung
Der Befehl Draft Form2DAnsicht erstellt 2D-Projektionen von ausgewählten Objekten, in der Regel 3D-Festkörper oder Arch Schnittebenen. Die Projektionen werden in der 3D-Ansicht dargestellt.
Draft Shape2DView projections can be displayed on a TechDraw Workbench page using the TechDraw DraftView command. Alternatively the TechDraw Workbench offer its own projection commands. But these create projections that are only displayed on the drawing page and not in the 3D view.
Projection of solid shapes onto the XY plane
Anwendung
- Optionally rotate the 3D view. The camera direction in the 3D view determines the projection vector. For example, a top view will project onto the XY plane. The projection vector is ignored for projections created from Arch SectionPlanes.
- Optionally select one or more objects.
- There are several ways to invoke the command:
- Press the Shape 2D view button.
- Select the Modification → Shape 2D view option from the menu.
- If you have not yet selected an object: select an object in the 3D view.
- The projected objects are created on the XY plane.
How to produce plans and sections with different linewidths
Drawings with different linewidths for viewed and cut lines can easily be produced by using two shape2Dview objects from a same Arch SectionPlane. One of the shape2Dview objects has its projection mode set to Solid, which renders the viewed lines, and another set to Cut lines or Cut faces to render the cut lines. The two shape2Dviews are then placed at the same location, one on top of the other.

To create a 2D projection use the make_shape2dview
method (introduced in version 0.19) of the Draft module. This method replaces the deprecated makeShape2DView
method.
shape2dview = make_shape2dview(baseobj, projectionVector=None, facenumbers=[])
baseobj
is the object to be projected.projectionVector
is the projection vector. If not supplied the Z axis is used.facenumbers
is a list of face numbers (0-based). If supplied only these faces are considered.shape2dview
is returned with the created 2D projection.
Change the ProjectionMode
property of the created object if required. It can be: "Solid"
, "Individual Faces"
, "Cutlines"
, "Cutfaces"
or "Solid faces"
.
