## Descriere

**Create an arc** is an icon button in the Sketcher geometries toolbar that groups tools to create an arc by picking three points. Click on the down arrow to its right to expand the icons below it and select a tool.

## Types of arcs

- Arc by Center and end points: Draws an arc by picking three points: the center, the start angle along the radius, and the end angle.
- Arc by end points and rim point: Draws an arc by picking three points: the start point, the end point and a point on the arc.
