Geometry Constraint

Geometry constraint can keep the certain relationship between the objects.

Geometry constraint includes parallel, perpendicular, horizontal, vertical, tangent, concentric, coincident, equal, collinear, symmetrical, fixed constraints and same size. The valid entities for geometry constraint includes line, circle (arc), point.
