Add a Radius Constraint

General

  • A radius constraint can be added to a circle and arc.
  • A radius constraint can be added to several circles and arcs at once.

Add a radius constraint in plane sketch

  1. Select Sketch | Constraints Add radius constraint.
  2. Select a circle or an arc.
  3. Click the position of the dimension.
    • The program opens the dialog box Edit Constraint.
  4. Edit the data in the Edit Constraint dialog box.
    • Edit Constraint Dialog Box.
    • At least check the value of the dimension.
    • Add a formula, if you want to control the geometry with a dimension table.
  5. Select OK.
    • If the radius constraint is the first radius constraint in the sketch, and there are no distance or diameter constraints in the sketch yet, then the radius constraint scales all lines in the sketch to match the entered dimension.
  6. Repeat steps 2 to 5 to add new radius constraints
  7. Stop adding radius constraints
    • Select another function or
    • press the V key or
    • press the Esc key or
    • click the middle mouse button.

Add a radius constraint to multiple circles or arcs at the same time

  1. Select the circles and arcs that you want to set the radius constraint to.
    • Hold down the Ctrl key while clicking the elements.
  2. Select the following contextual function: Constraints > Radius.
  3. Continue as above steps 2...5.

Dimension the radii of an ellipse

Add a radius dimension to the axis of an ellipse by selecting a line either near the main axis of the ellipse or near the second axis, depending on to which axis you want to add the radius dimension.
