The tool can measure edges or lines directly attached to solid bodies; if the body changes, the dimension updates itself. The tool can also measure a diameter or radius of curvature such as those produced by a [[Draft Arc]], or by the [[Part Fillet]], [[Sketcher CreateFillet]], and [[PartDesign Fillet]] operations.

The resulting dimension is placed in the 3D view, and is considered a Draft object. This object can be displayed on a [[TechDraw Workbench]] Page, using the [[TechDraw NewDraft]] or [[TechDraw NewArch]] tools. Alternatively, TechDraw has its own tools to display dimensions, such as [[TechDraw Dimension Length]] and [[TechDraw Dimension Radius]]; however, these tools are meant for preparing technical drawings, so they create the dimensions only in the drawing page, and not in the 3D view.

The dimension can be edited by double clicking on the element in the tree view, or by pressing the {{Button|[[Image:Draft Edit.svg|16px]] [[Draft Edit]]}} button. Then you can move the points to a new position.
==Available dimension types==

* '''Linear dimensions''': by picking any 2 points or any straight edge with {{KEY|ALT}} pressed.
The measuring points can be changed after creation by changing the start and end properties.
* '''Horizontal/vertical dimensions''': by pressing {{KEY|SHIFT}} while the second point is selected.

* '''Diameter dimensions''': by picking a curved edge with {{KEY|ALT}} pressed.
The position of the measurement line can also be changed after creation by changing its direction property.
* '''Radius dimensions''': by picking a curved edge with {{KEY|ALT}} pressed, then pressing {{KEY|SHIFT}}.

* '''Angular dimensions''': by picking 2 straight edges with {{KEY|ALT}} pressed.
===Available dimension types===
Release the modifier ({{KEY|Alt}} or {{KEY|Shift}}) after picking a point or an edge.

* Linear dimensions: hold the {{KEY|Alt}} key, or click on the {{Button|[[Image:view-select.svg|16px]] select edge}} button, and pick a straight edge, then pick a second point to draw the dimension line parallel to that edge.
:{{emphasis|Note:}} you can also pre-select the edge before calling the tool.
* Horizontal and vertical dimensions: pick one point, then pick a second point, then hold the {{KEY|Shift}} key and move the pointer horizontally or vertically, then pick a third point to draw the dimension line parallel to either the X axis or the Y axis.
:{{emphasis|Note 1:}} click and hold {{KEY|Shift}} and move the pointer in different directions many times until the dimension line aligns to the desired axis. Clicking {{KEY|Shift}} while the pointer is far from the first point will usually align the dimension to the X axis; if the pointer is close to the first point it will usually align the dimension to the Y axis.
:{{emphasis|Note 2:}} instead of picking two points, pick an edge while holding {{KEY|Alt}}.
* Diameter dimensions: hold the {{KEY|Alt}} key and pick a curved edge, then pick a second point to draw the dimension line.
** Radius dimensions: hold the {{KEY|Alt}} key and pick a curved edge, then hold the {{KEY|Shift}} key and pick a second point to draw the dimension line.
* Angular dimensions: hold the {{KEY|Alt}} key and then pick two straight edges, then pick a point between the two edges to show the acute or obtuse angle, or elsewhere to show a supplementary or explementary angle.
:{{Emphasis|Note:}} the displayed angle largely depends on the original position of the selected edges. If you would like to display a particular angle, you may have to add auxiliary [[Draft Line]]s that extend from the original edges, and measure these extensions.

{{Emphasis|Note:}} by pre-selecting an edge, or by picking it with {{KEY|Alt}} or {{Button|[[Image:view-select.svg|16px]] select edge}}, the dimension will become {{emphasis|parametric}}, that is, it will remember which edge it is bound to. If the endpoints of that edge move later on, the dimension will follow them, and adjust the displayed measurement.

* Press {{KEY|T}} or click the checkbox to toggle ''continue'' mode. If continue mode is on, the Dimension tool will restart after you give the final point, allowing you to draw another dimension without pressing the tool button again; the following dimensions will start from the final point of the previous dimension, and will share the same baseline.
* Pressing {{KEY|SHIFT}} will [[Draft_Constrain|constrain]] the dimension horizontally or vertically, or, when working on a circular edge, switches between diameter and radius modes.
* Hold {{KEY|Ctrl}} while drawing to force [[Draft_Snap|snapping]] your point to the nearest snap location, independently of the distance.
* Press {{KEY|R}} or click the checkbox to check/uncheck the {{KEY|'''Relative'''}} button. If relative mode is on, the coordinates of the next point are relative to the last one. If not, they are absolute, taken from the (0,0,0) origin point.
* Hold {{KEY|Shift}} while drawing to [[Draft_Constrain|constrain]] your next point horizontally or vertically in relation to the previous one, and to switch between diameter and radius modes.
* Press {{KEY|T}} or click the checkbox to check/uncheck the {{KEY|'''Continue'''}} button. If continue mode is on, you will be able to draw continued dimensions, one after the other, that share the same baseline.
* Press {{KEY|ESC}} or the {{KEY|'''Cancel'''}} button to abort the current Line command.
* Press {{KEY|Esc}} or the {{Button|Close}} button to abort the current command, and finish ''continued'' dimensions; dimensions already placed will remain.
* By picking an existing edge with {{KEY|ALT}}, instead of entering measurement points, the dimension will become '''parametric''' and remember which edge it is bound to. If the endpoints of that edge move later on, the dimension will follow them.
* If an edge is selected before starting the Dimension command, the created dimension will also be '''parametric'''.
* The direction of the dimension can be changed afterwards, by modifying its "Direction" property

Beskrivning

Detta verktyg ber användaren om två punkter för att definiera det segment som ska måttsättas, sedan en tredje punkt för att placera dimensionslinjen.

The tool can measure edges or lines directly attached to solid bodies; if the body changes, the dimension updates itself. The tool can also measure a diameter or radius of curvature such as those produced by a Draft Arc, or by the Part Fillet, Sketcher CreateFillet, and PartDesign Fillet operations.

The resulting dimension is placed in the 3D view, and is considered a Draft object. This object can be displayed on a TechDraw Workbench Page, using the TechDraw NewDraft or TechDraw NewArch tools. Alternatively, TechDraw has its own tools to display dimensions, such as TechDraw Dimension Length and TechDraw Dimension Radius; however, these tools are meant for preparing technical drawings, so they create the dimensions only in the drawing page, and not in the 3D view.

Dimension defined by three points

Bruk

  • Markera 3 punkter i ett tomt område i 3d vyn, eller på ett existerande objekt.
  • Nedtryckning av CTRL kommer att snäppa din punkt till tillgängliga snäpp-punkter.
  • Nedtryckning av SHIFT kommer att begränsa dimensioneringen horisontellt eller vertikalt.
  • Skriv in siffror för att manuellt mata in en koordinat.
  • Om du trycker på ESC så avbryts funktionen.

The dimension can be edited by double clicking on the element in the tree view, or by pressing the Draft Edit button. Then you can move the points to a new position.

The measuring points can be changed after creation by changing the start and end properties.

The position of the measurement line can also be changed after creation by changing its direction property.

Available dimension types

Release the modifier (Alt or Shift) after picking a point or an edge.

  • Linear dimensions: hold the Alt key, or click on the select edge button, and pick a straight edge, then pick a second point to draw the dimension line parallel to that edge.
Note: you can also pre-select the edge before calling the tool.
  • Horizontal and vertical dimensions: pick one point, then pick a second point, then hold the Shift key and move the pointer horizontally or vertically, then pick a third point to draw the dimension line parallel to either the X axis or the Y axis.
Note 1: click and hold Shift and move the pointer in different directions many times until the dimension line aligns to the desired axis. Clicking Shift while the pointer is far from the first point will usually align the dimension to the X axis; if the pointer is close to the first point it will usually align the dimension to the Y axis.
Note 2: instead of picking two points, pick an edge while holding Alt.
  • Diameter dimensions: hold the Alt key and pick a curved edge, then pick a second point to draw the dimension line.
    • Radius dimensions: hold the Alt key and pick a curved edge, then hold the Shift key and pick a second point to draw the dimension line.
  • Angular dimensions: hold the Alt key and then pick two straight edges, then pick a point between the two edges to show the acute or obtuse angle, or elsewhere to show a supplementary or explementary angle.
Note: the displayed angle largely depends on the original position of the selected edges. If you would like to display a particular angle, you may have to add auxiliary Draft Lines that extend from the original edges, and measure these extensions.

Note: by pre-selecting an edge, or by picking it with Alt or select edge, the dimension will become parametric, that is, it will remember which edge it is bound to. If the endpoints of that edge move later on, the dimension will follow them, and adjust the displayed measurement.

Options

  • Press X, Y or Z after a point to constrain the next point on the given axis.
  • To enter coordinates manually, simply enter the numbers, then press Enter between each X, Y and Z component. You can press the add point button when you have the desired values to insert the point.
  • Press R or click the checkbox to toggle relative mode. If relative mode is on, the coordinates of the next point are relative to the previous one; if not, they are absolute, taken from the origin (0,0,0).
  • Press T or click the checkbox to toggle continue mode. If continue mode is on, the Dimension tool will restart after you give the final point, allowing you to draw another dimension without pressing the tool button again; the following dimensions will start from the final point of the previous dimension, and will share the same baseline.
  • Hold Ctrl while drawing to force snapping your point to the nearest snap location, independently of the distance.
  • Hold Shift while drawing to constrain your next point horizontally or vertically in relation to the previous one, and to switch between diameter and radius modes.
  • Press Esc or the Close button to abort the current command, and finish continued dimensions; dimensions already placed will remain.

  • DataEnd: specified the end point of the distance to measure.
  • DataDimline: specifies a point through which the dimension line must pass.
  • DataDistance: (read-only) indicates the measured length.

It can be a font name, such as "Arial", a default style such as "sans", "serif" or "mono", a family such as "Arial,Helvetica,sans" or a name with a style such as "Arial:Bold". If the given font is not found on the system, a generic one is used instead.
  • VyFont Size: specifies the size of the letters. If the dimension object is created in the tree view but no text is visible, increase the size of the text until it is visible.
  • VyFlip Text: specifies whether to flip the orientation of the text indicating the measurement.
  • VyText Position: specifies the position of the text in absolute coordinates, referred to the origin (0,0,0); leave this property at its default value (0,0,0) to display the text next to the dimension line.
  • VyText Spacing: specifies the space between the text and the dimension line.
  • VyOverride: specifies a custom text to display instead of the actual measurement. Use the string $dim inside the text to display the measurement value.
  • VyDecimals: specifies the number of decimal places to display on the measurement.

  • VyUnit Override: specifies a unit in which to express the measurement, for example, "km", "m", "cm", "mm", "mi", "ft", "in"; leave this property blank to use the default units. introduced in version 0.17

Scripting

See also: Draft API and FreeCAD Scripting Basics.

The Dimension tool can be used in macros and from the Python console by using the following function:

Dimension = makeDimension(p1, p2, p3=None, p4=None)

There are various ways to invoke this function, depending on the arguments passed to it:

Dimension = makeDimension(p1, p2, p3=None)
Dimension = makeDimension(object, i1, i2, p4=None)
Dimension = makeDimension(object, i1, mode, p4=None)
  • Creates a linear Dimension by measuring the distance between points p1 and p2.
  • Creates a linear Dimension linked to object, measuring the distance between its vertices indexed i1 and i2.
  • Creates a circular Dimension linked to object, with i1 being the index of the curved edge to measure, and mode being either "radius" or "diameter" to specify the type of dimension.
    • p3 in the first call, and p4 in the other two, specify an optional point through which the dimension line should go.
    • All points are defined by their FreeCAD.Vector.

To create an angular dimension use the following function:

Dimension = makeAngularDimension(center, angles, p3, normal=None)
Dimension = makeAngularDimension(center, [angle1, angle2], p3, normal=None)
  • Creates an angular Dimension from the given center point, the angles list with two elements, and the point p3 through which the arc should go.
    • If angle1 > angle2, the displayed angle is the difference angle1 - angle2; otherwise, the explementary angle is displayed, 360 - (angle2 - angle1).
    • The angles should be given in radians; the math.radians() function can be used to convert angles given in degrees.

The view properties of Dimension can be changed by overwriting its attributes; for example, overwrite ViewObject.FontSize with the new size in millimeters.

Example:

import math, FreeCAD, Draft

p1 = FreeCAD.Vector(0, 0, 0)
p2 = FreeCAD.Vector(1000, 1000, 0)
p3 = FreeCAD.Vector(-2500, 0, 0)
Dimension1 = Draft.makeDimension(p1, p2, p3)
Dimension1.ViewObject.FontSize = 200

Polygon = Draft.makePolygon(3, radius=1000)
p4 = FreeCAD.Vector(-2000, 1500, 0)
Dimension2 = Draft.makeDimension(Polygon, 1, 2, p4)
Dimension2.ViewObject.FontSize = 200

center = FreeCAD.Vector(2000, 0, 0)
p5 = FreeCAD.Vector(3000, 1000, 0)
angle1 = math.radians(45)
angle2 = math.radians(10)
Dimension3 = Draft.makeAngularDimension(center, [angle1, angle2], p5)
Dimension3.ViewObject.FontSize = 200

Dimension4 = Draft.makeAngularDimension(center, [angle2, angle1], p5*1.2)
Dimension4.ViewObject.FontSize = 200
