Description

The Sketcher ConstrainRadiam tool fixes the radius of arcs and B-spline weight circles, and the diameter of circles.

Usage

See also: Drawing aids.

Continue mode

1. Make sure there is no selection.
2. 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 auto radius/diameter option from the dropdown.
   • If this preference has a different value (and in version 0.21 and below): press the Constrain auto radius/diameter button.
   • Select the Sketch → Sketcher constraints → Constrain auto radius/diameter option from the menu.
   • introduced in version 1.0: Right-click in the 3D view and select the Dimension → Constrain auto radius/diameter option from the context menu.
   • Use the keyboard shortcut: K then S.
3. The cursor changes to a cross with the tool icon.
4. Do one of the following:
   • Select the edge of a circle or arc.
   • Select the edge of a B-spline weight circle.
5. If a driving dimensional constraint is created, depending on the preferences, a dialog opens to edit its value.
6. A constraint is added.
7. Optionally keep creating constraints.
8. To finish, right-click or press Esc, or start another geometry or constraint creation tool.

Modo de execução única

1. 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.
2. Invoke the tool as explained above.
3. Optionally edit the constraint value.
4. 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('Radius', ArcOrCircle, App.Units.Quantity('123.0 mm')))
Sketch.addConstraint(Sketcher.Constraint('Diameter', ArcOrCircle, App.Units.Quantity('246.0 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.
