Arc

Draw a circular arc using a start point, end point, and a third point that sets curvature.

Purpose

Draw a circular arc using a start point, end point, and a third point that sets curvature.

Start or edit a sketch, open Draw, and choose Arc.

The third point controls radius and which side of the start-to-end chord the arc follows.

Creates a reference arc that does not form a profile boundary.

The three accepted points create an editable circular arc.

Move endpoints or the arc point and apply Coincident, Tangent, Equal, or dimensional constraints.

The arc bends the wrong way or becomes nearly straight.

Place the third point on the other side of the chord or farther from the start-to-end line.
