GEOMCONSTRAINT Command — GstarCAD 2027
GEOMCONSTRAINT Command
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:
GCCOINCIDENT
Constrains two points to coincide or a point to lie on a curve (or the curve's extension).
GCCOLLINEAR
Aligns two or more line segments to be in the same straight line direction.
GCCONCENTRIC
Constrains two arcs, circles, or ellipses to share the same center point.
GCFIX
Locks a point or a curve in place, preventing it from moving.
GCPARALLEL
Makes selected lines parallel to each other.
GCPERPENDICULAR
Positions selected lines at right angles to each other.
GCHORIZONTAL
Aligns a line or a pair of points to be parallel to the X-axis of the current coordinate system.
GCVERTICAL
Aligns a line or a pair of points to be parallel to the Y-axis of the current coordinate system.
GCTANGENT
Constrains two curves to be tangent to each other or their extensions to be tangent.
GCSYMMETRIC
Applies symmetry constraint to selected objects relative to a selected line.
GCSMOOTH
Constrains a spline curve to be continuous and maintain G2 continuity with other spline curves, lines, arcs, or polylines.
GCEQUAL
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.
