Menu : CURVE

Command: Design:Arc

Shortcut : None

This command creates an arc in the target curve set. A parameter box appears requesting the start and end angles for the arc, the coordinates of the location of the center point, and the number of control points to be used for the arc.

Angular values in DeskArtes are measured anti-clockwise in degrees, with zero being located at 3 O’clock. The example below shows an arc starting at 0 degrees and ending at 90 degrees.

The number of control points chosen is important. Arcs with low numbers of points will have poor accuracy compared to a true circle. Given the same number of knot points, Bézier circles are more accurate than B-splines.

The curve type depends on SettingsÞREPS.
