Make 2D stuck at 99% in Rhino 8

I just got rhino again for my pc/desktop computer to work on my portfolio & downloaded rhino 8. After working on some models the past few days, i havent been able to successfully use the make 2D command anymore & im not sure what to do. It will stay loading for hours at 99% before i’ll eventually force quit it & a box will pop up with a server issues.

I’ve tried to join as many meshes/polylines as possible, increased the tolerance, & tried opening in a new file but not sure what else there would be to do to get it to finish. Any thoughts are welcome!


try and check the model.

Especially the scaling might help our
