Summary
You can also add an additional curve over the closed loop to constrain and
guide the patch surface.
When you create a patch surface, you can specify surface continuity and bulge
magnitude. If the
SURFACEASSOCIATIVITY on page 1507 system variable is set
to 1, associativity is maintained between the patch surface and the originating
edges or curves.
List of Prompts
The following prompts are displayed.
Select Surface Edges or Curves
Select one or more closed surface edges (not the surface itself) or one or more
curves. You cannot choose both edges and curves at the same time.
Continuity
Measures how smoothly surfaces flow into each other. The default is G0. See
Understand Surface Continuity and Bulge Magnitude. Select a value or use
the grip to change the continuity.
Bulge Magnitude
For best results, enter a value between 0 and 1 to set the roundness of the
patch surface edge where it meets the originating surface. The default is 0.5.
