Construction Aid Circle > On Circle (Construct Menu)

This command draws a Construction Aid circle on top of an existing circle or circle part.

This command is particularly useful if a circle or circle arc which currently only exists in the drawing is to be used as a Construction Aid circle.

If a Construction Aid circle is to be drawn while working in isometric or dimetric views, this must be done with the command Construction Aid Ellipse > Vector - Vector because the result on the page is not circular but elliptical.

Any circle which exists on its own or within an existing object can be identified as a reference object. This can be the arc of a circle segment or a circle arc within a surface.
