Construction Aid Endless Line > Mid-Perpendicular (Construct Menu)

This command draws a Construction Aid endless line which runs along the mid-perpendicular of another line. The Construction Aid line is constructed so that the right angle is given in normal view. If working with a distorted view (e.g. when using dimetric view) the visible angle is not 90 degrees.

Any line in an existing object can be identified as the reference line. This can also be a side of a rectangle or a part of a circle segment. Construction Aid endless lines cannot be used because they have no "middle".
