What is interesting is that I saved out a parasolids of this part and opened it on my laptop which is running 2015, sp5. The section works fine there.
I have 2016 on my (older) workstation and that is where this is failing. It still functions, but is a little slow. I am trying to figure out if I have a hardware problem or if there is something in 2016 that is causing this to fail. I am used to looking for tangent conditions and checking to see if surfaces are causing a problem and see none of those issues. Plus, when I simply section the 3d model, it cuts fine. It's in the drawing that it fails. If I get replies that it sections file when others of you open it, then I will know I'll have to take the time to set myself up for only using my laptop.
