An arc is a sector of a circle.
There are two types of arc: full (circle) and partial. A full arc has a span of 360°, with start and end points that coincide, and a single key point at its centre. A partial arc has three key points: the start, end, and centre positions.
To create an arc:
- Click Wireframe tab > Create panel > Arc, and choose from:
- Full — to create a full arc (circle).
- Fitted — to create an arc through three points or items.
- Swept — to create an arc through a centre, radius, and span.
