Converting to and Editing a Variable Radius Round

To convert a constant-radius round to a variable-radius round, right-click and select the Edit as Variable Radius Round option.

  • Click the Pull arrow on an end of the round face and drag toward or away from the face to adjust the radius at the edge of the round.
  • Click the Pull arrow pointing toward the center of the face and drag it along the face (or enter a length or percent) to set another point where you can adjust the round's radius.
  • Hold Ctrl and drag to copy a control point.
  • Press Tab to switch among and edit the dimensions by typing a number.
  • Two rounds that intersect at a shared edge can be made variable together by selecting the shared sharp edge for modification. Both rounds become variable at that point. They can be made variable independently by selecting the sharp end edge that is not shared by the rounds.

    In the Pull tool, when you select an edge of a constant radius round, the Smooth option becomes enabled if the geometry allows it. When checked, the transition between radius at each end of the round will vary smoothly instead of linearly. Once set, the Smooth option remains set for subsequent rounds until you change it.


Example:
The image below shows a smooth variable radius round.
Editing a variable radius round. The variable radius round handles have a drag (ball) handle. The center Radius Handle cannot be dragged, all radii values are adjusted at once.
Click the ball and drag to add and place a new radius handle.
