Construction Aid Circle Arc > Circumcircle (Construct Menu)

This command draws a Construction Aid circle arc which ends at two given points and runs through a third.

If a Construction Aid circle arc is to be drawn while working in isometric or dimetric view, then the command Construction Aid Ellipse Arc > Vector - Vector must be used, because the result on the page is elliptical not circular.

The start point can be entered by clicking at any point in the drawing.

The end point can be entered by clicking at any point in the drawing.

The third point through which the Construction Aid circle arc should run, can be entered with the mouse by clicking anywhere in the drawing.

The resulting arc is not dependent on the current arc direction, as the arc direction is determined implicitly by the position of the third point.

The arc direction settings of existing arcs are not affected by changes to the current arc direction. To change the arc direction of an existing arc, use the command Transform Object to > Invert.
