Summary
When you apply a geometric constraint to a pair of objects, the order in which
the objects are selected and the point on which each object is selected can
affect how the objects are positioned relative to each other.
The following table outlines the valid constraint points for an object.
Valid Constraint PointsObjects

The following commands are equivalent to each GEOMCONSTRAINT option:
Horizontal (
GCHORIZONTAL (page 456))
Causes lines or pairs of points to lie parallel to the X axis of the current
coordinate system.
Vertical (
GCVERTICAL (page 463))
Causes lines or pairs of points to lie parallel to the Y axis of the current
coordinate system.
Perpendicular (
GCPERPENDICULAR (page 458))
Causes selected lines to lie 90 degrees to one another.
Parallel (GCPARALLEL (page 457))
