Hey bullet, thanks for the advice. Sounds great to me. What i need in the end is a *stl file that contains my measurements etc.. I uploaded a few pictures. First one is the front. The grey object is the reference with the difference that I use the purple holes instead of the 4 that are already in. The rest is exact how it should be. Reference 2 shows the red line that I have to be able to edit in the end (crease it or whatever). Reference 4 is the mesh that i have currently come up with. My goal was to make a clean basic mesh in order to edit/sculpt details into it in zbrush. But when I try to insert edge loops to make the corners more crisp it all messes up. So thats my problem right now. The blue lines in 2 and 3 show where I have to detail the surface afterwards in zbrush. Thanks for the help Appreciate. Philcc
