GEOMCONSTRAINT command

Applies geometric relationships between entities, on entities, and on valid constraint points.

Description

Constraints keep entities in a fixed position, such as perpendicularly or vertically.

Note: Geometric constraints can be applied to the following entities and their constraint points:


Entity Type	Valid Constraint Points
Lines	Endpoints, midpoint
Arcs, elliptical arcs	Endpoints, center point, midpoint
Circles, ellipses	Center point
Polyline segments	Endpoints, vertices, midpoints
Polyline arcs	Endpoints, vertices, midpoints, center points
Splines	Endpoints
Inserted entities: blocks, xrefs, text, mtext, attributes, tables	Insertion points

Horizontal: Constrains entities or pairs of points to lie parallel to the X-axis of the current coordinate system. See the GCHORIZONTAL command.

Vertical: Constrains entities or pairs of points to lie parallel to the Y-axis of the current coordinate system. See the GCVERTICAL command.

Perpendicular: Constrains two entities to lie perpendicularly to each other. See the GCPERPENDICULAR command.

PArallel: Forces two entities to be parallel to one other. See the GCPARALLEL command.

Tangent: Constrains two entities to maintain a point of tangency to each other or their extensions. See the GCTANGENT command.

SMooth: Forces a spline to maintain fluid geometric continuity with another spline, line, arc or polyline. See the GCSMOOTH command.

Coincident: Applies a coincident geometrical constraint to two points or constrains a point to an entity. See the GCCOINCIDENT command.

CONcentric: Constrains the center points of circles, arcs, ellipses or elliptical arcs to coincide. See the GCCONCENTRIC command.

Symmetric: Constrains two entities or points to lie symmetrically with respect to a selected line. See the GCSYMMETRIC command.

Equal: Constrains circular entities to the same radius, or linear entities to the same length. See the GCEQUAL command.

Fix: Constrains points and entities at a fixed position. See the GCFIX command.
