Description

This tool draws a circle by picking three points on the circle outline. When starting the tool, the mouse pointer changes to a white cross with a red circle icon. Besides are coordinates shown in real time.

Usage

• Pick points on an empty area of the 3D view, or on an existing object (auto constraints must be active in TaskView).
• Pressing Esc or clicking the right mouse button cancels the function.
