The [[Image:Sketcher_ConstrainDiameter.svg|24px]] [[Sketcher_ConstrainDiameter|Sketcher ConstrainDiameter]] tool fixes the diameter of circles and arcs. It cannot be used for [[Sketcher_CreateBSpline#Notes|B-spline weight circles]]. |
|||
This constraint constrains the value of the diameter of a circle or arc to have a specific value. If more than one circle or arc is selected before launching the command, a prompt will ask if all selected elements should share the same diameter. In the case of an affirmative response, one diameter constraint will be added, and [[Sketcher ConstrainEqual|equal length]] constraints will be added to all elements. In the negative, separate diameter constraints will be created for each circle/arc but with equal values to be edited separately after creation. |

Description
The Sketcher ConstrainDiameter tool fixes the diameter of circles and arcs. It cannot be used for B-spline weight circles.
Usage
See also: Drawing aids.
Continue mode
- Make sure there is no selection.
- There are several ways to invoke the tool:
- introduced in version 1.0: If the Dimensioning constraints preference is set to
Single tool
(default): press the down arrow to the right of the button and select the Constrain diameter option from the dropdown. - If this preference has a different value (and in version 0.21 and below): press the Constrain diameter button.
- Select the Sketch → Sketcher constraints → Constrain diameter option from the menu.
- introduced in version 1.0: Right-click in the 3D view and select the Dimension → Constrain diameter option from the context menu.
- Use the keyboard shortcut: K then O.
- introduced in version 1.0: If the Dimensioning constraints preference is set to
- The cursor changes to a cross with the tool icon.
- Select the edge of a circle or arc.
- If a driving dimensional constraint is created, depending on the preferences, a dialog opens to edit its value.
- A constraint is added.
- Optionally keep creating constraints.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
Run-once mode
- Select the edge of one or more circles or arcs.
- Invoke the tool as explained above.
- Optionally edit the constraint value.
- Depending on the selection one or more constraints are added, see Notes.
Notes
- If driving constraints are created and multiple elements that are not external geometry have been pre-selected, only the first of those receives a dimensional constraint, while between the first and the others Equal constrains are applied.
Scripting
Sketch.addConstraint(Sketcher.Constraint('Diameter', ArcOrCircle, App.Units.Quantity('123.0 mm')))
The Sketcher scripting page explains the values which can be used for ArcOrCircle
, and contains further examples on how to create constraints from Python scripts.
