Hello,

I have a question about saving a .SLDPRT-file as a .STL-file so I can send it to my 3D printer. I have done this loads of times and it never gave any problems. I am now trying to save a part with a lot of holes and chamfers in it. The part looks fine when I open it as a SLDPRT- file but when I open it as a STL-file there are some weird surfaces added (see pictures). I have no idea how these got there. Can anybody tell me what I can do to fix this? I already tried closing and reopening SolidWorks and I saved it as a STL-file several times.

Thanks in advance!

Thomas
