First post here so call me out if I'm doing something wrong. I've searched for something relevant to what I'm working on but found nothing.
What I have is model of a hand. The original file is a multi surface .IGS. What I want to do extrude the hand into the background from the front plane. You would look at it from the front and look normal, but the back be a flat face. This sounds like an easy task, but nothing I've tried has worked for me. I thought maybe I could extrude lines I converted from the silhouette, but the curves were getting tricksy with me. Any advice on how to approach this would be much appreciated.
Let me know if you dont understand my explanation or something.
I've included my slightly modified (scaled) version as well as the original .igs file.
