Description:
|
This API projects
in_curve onto
in_surface, returning the result in
is_surface. in_range is the parameter range of
in_curve.
|
|
|
The input curve and surface should both be in world coordinates. They might not be if their owning body contains a transformation, and may need to be converted. See the Scheme command,
edge:project-to-face, for an example of how to do this.
|
|
|
Only that part of the curve for which a perpendicular projection onto the surface exists will be projected. Parts which can only be projected to the boundaries of the surface will be excluded.
|
|
|
Errors:
|
Curve or surface not in world coordinates.
|
|
|
Limitations:
|
If the curve has a perpendicular projection onto the surface over more than one distinct interval, the function will fail, as it can only return a single output curve.
