When you use the Segment tool in lines, arcs,
circles, splines, parabolas, ellipses, partial ellipses, or conics, an equidistant relation
is applied to the sketch points.
The equidistant relation creates space between the sketch points on the line,
arc, or circle. If you drag or resize the line, arc, circle, splines, parabolas,
ellipses, partial ellipses, or conics, the sketch points automatically adjust to remain
equidistant along the segment.
Deleting any of the equidistant relations in a sketch point group deletes the
entire relations group. After deleting an equidistant relation, the sketch points remain
in their previous locations with a coincident relation to the entity onto which they
were placed.
