Description
The Sketcher ConstrainRadius tool fixes the radius of circles, arcs or B-spline weight circles.
If driving constraints are being applied and multiple elements that are not external geometry have been pre-selected, a driving Radial constraint will only be applied to the first of those, and between the first and the others Equal constrains will be applied.
Usage
See also: Drawing aids.
Continue mode
- Make sure there is no selection.
- There are several ways to invoke the tool:
- Press the Constrain radius button.
- Select the Sketch → Sketcher constraints → Constrain radius option from the menu.
- introduced in version 0.22: Right-click in the 3D view and select the Dimension → Constrain radius option from the context menu.
- Use the keyboard shortcut: K then R.
- Do one of the following:
- Select the edge of a circle or arc.
- Select the edge of a B-spline weight circle.
- If a driving constraint is created, and the Ask for value after creating a dimensional constraint option is selected (default) in the Sketcher Preferences:
- A pop up dialog opens to edit the constraint value.
- Press the OK button to confirm.
- A constraint is added.
- Optionally keep creating constraints.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool
Once-only mode
- Do one of the following:
- Select the edge of one or more circles or arcs.
- Select the edge of one or more B-spline weight circles.
- Invoke the tool as explained above.
- Edit and/or confirm the constraint value as explained above.
- Depending on the selection one or more constraints are added.
Scripting
Sketch.addConstraint(Sketcher.Constraint('Radius', 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.
