Description

The Sketcher ConstrainRadius tool fixes the radius of circles, arcs and B-spline weight 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 0.22: 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 radius option from the dropdown.
    • If this preference has a different value (and in version 0.21 and below): 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.
  3. For further steps see Sketcher ConstrainRadiam.

Run-once mode

See Sketcher ConstrainRadiam.

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.
