GCSMOOTH (Command)

Constrains a spline to be contiguous and maintain G2 continuity with another spline, line, arc, or polyline.


This command is equivalent to the Smooth option in GEOMCONSTRAINT.

Following are the valid constraint objects and points:

The splines are updated to be contiguous with one another.

Note: Endpoints of the curves to which you apply the smooth constraints are made coincident.

The following prompts are displayed.


Selects an endpoint of a curve.

First Spline Curve

Selects the first spline curve to be constrained.

Second Curve

Selects the second curve to be made continuous with the first spline curve.
