Insert Circle Numerically

A circle can be defined either by a center and a radius, or by three different points. Circles can be entered either graphically using the cursor (most common) or using the New Line dialog window (below).

The list of points defining the circle must be entered in the General Tab, while coordinates of points defining the circle, its center and radius are entered in the Circle Tab.

Adjustable Point: When a radius or the center of an arc is modified, it is usually also necessary to modify the location of one of the arc definition points. An adjustable point enables one to choose a point whose coordinates are to be changed.

The Circle can be edited using the same dialog window.
