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

Options

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.
COLlinear
Forces entities to be collinear. See the GCCOLLINEAR 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.
