An unusual arc property, used only in circular geometry, is curvature. Although most arcs cannot handle curvature, those in the Artwork and Round CMOS ("rcmos") technologies can.

Figure 5.11
The Curve through Cursor command (in menu Edit / Arc) requests that the currently highlighted arc curve in such a way that it passes through the location of the cursor. The Curve about Cursor command requests that the currently highlighted arc curve between its endpoints such that the center of curvature is at the location of the cursor. After issuing these commands, click and drag to see how the arc will curve.

The Remove Curvature command makes the arc straight.
