If the flange surface is created from input curves projected onto a
surface, you can extrapolate the edges of the created surface to the edges of the support
surface.
Note:
The created surface can only be extrapolated if the rails can
reach the support surface edges.
Before you begin: Open a 3DShape containing a surface and a curve projected onto
it.
Create a flange surface from the curve
projection.
By default, the flange surface is created with the
Extrapolation option Off.
Select Both to extrapolate the flange surface to both ends
of the support surface.
