Description
This tool draws an arc by picking three points: the start point, the end point and a point on the arc. When starting the tool, the mouse pointer changes to a white cross with a red 3 point arc icon: . The coordinates of the pointer are shown beside it in blue in real time.
Usage
- There are several ways to invoke the command:
- Press the End points and rim point button.
- Select the Sketcher → Sketcher geometries → Create arc by three points option from the menu.
- The keyboard shortcut: G then 3, A.
- Pick points in an empty area of the 3D view, or on an existing object (auto constraints must be active in the Task panel).
- Pressing Esc or clicking the right mouse button cancels the function.
