I am trying to project a square profile on a freeform surface using UF_MODL_create_proj_curves.
I am getting the projection correctly but when I try to extrude it, its giving me a sheet instead of a solid (See image)
Following is the extrusion:
The same procedure works fine when I extrude the profile on to a flat surface:
Is there any way I can fix this problem and get a solid extrusion even in case of a freeform surface?
In general, extruding non-planar curves will result in a sheet body. Instead of extruding non-planar curves, extrude the planar curves and trim the result to the desired face.
If you want to get a "boss" type feature where the top of the boss mimics the freeform surface, one way to do it is:
