Smooth
Summary
This command is equivalent to the Smooth option in GEOMCONSTRAINT.
Following are the valid constraint objects and points:
- Spline, line
- Polyline segment
- Arc
- Polyline arc
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.
