Function Description:
Applies geometric relationships between objects or between points on objects, or maintains these relationships permanently.
When applying geometric constraints to a pair of objects, the order in which you select the objects and the points on each object can affect how the objects are positioned relative to each other.

Command Prompts:
Enter constraint type [Horizontal (H) / Vertical (V) / Perpendicular (P) / Parallel (PA) / Tangent (T) / Smooth (SM) / Coincident (C) / Concentric (CON) / Collinear (COL) / Symmetric (S) / Equal (E) / Fixed (F)] \<Horizontal>: Each branch option of this command is equivalent to each of the separate commands 1-12.
The following commands are equivalent to each GEOMCONSTRAINT option:
Constrains two points to coincide or a point to lie on a curve (or the curve's extension).
Aligns two or more line segments to be in the same straight line direction.
Constrains two arcs, circles, or ellipses to share the same center point.
Locks a point or a curve in place, preventing it from moving.
Makes selected lines parallel to each other.
Positions selected lines at right angles to each other.
Aligns a line or a pair of points to be parallel to the X-axis of the current coordinate system.
Aligns a line or a pair of points to be parallel to the Y-axis of the current coordinate system.
Constrains two curves to be tangent to each other or their extensions to be tangent.
Applies symmetry constraint to selected objects relative to a selected line.
Constrains a spline curve to be continuous and maintain G2 continuity with other spline curves, lines, arcs, or polylines.
Adjusts the size of selected arcs and circles to have the same radius, or adjusts the size of selected lines to have the same length.
