Could you upload your file.
...maybe try, Fill Surface?
The file is too large and unable to create a compressed folder still trying to find a solution
Try Fill Surface as Paul Salvador said or use Google Drive to upload large file.
(export only surfaces used/selected).. that is, select only the surfaces involved with that edge and saveas Parasolid x_t (native kernel)
Could you extrude a surface and use it with a trim to get the target face you're after? It looks fairly straight or normal to your bottom boundary profile selection on that plane.
I have been unable to extrude a surface because I can't find a bottom edge. Is there a way to make it a edge? It keep saying mirror and split line feature rather than a edge. I attached a Parasolid file and was unable to get fill surface to work either. Also anyone has a solution to placing a face on the top of the model.
I extended the surface and used a boundary surface. Now, I am working on making a plane on the top to produce some detail on the top.
There is a gap here when working take this account.
Okay, I extended it a little then used the boundary patch still working on this project.
