Whenever I perform a specific projection to a surface, when I save, the next time I open the file I get an error that says "object reference not set to an instance of an object"

Hello Jamie Levinson

Does this issue happen with any one specific file ? Can you please share that file if possible?

Can you please use the "Check geometry" feature to see if there are any geometry issues with the projection? If there are, please try to rectify them and try again.

So, it only happens when I do one specific projection. Other projections seems to work fine. So, I did use the "Check Geometry" feature. I get some split edges and repair those however, I have done that every time and the problem still occurs. Here are the files before and after the projection. I project "Group 1" through the entire outer part. I project through the entire solid. When I open the file after saving it after the projection, no matter what happens, any action results in an error.

 

P.S. Sorry it took so long to respond. Work kept me busy.

So, I figured out a way to fix it was to detach the surfaces that I thought were causing the problem, and then recombining them. For holes that were causing them, I detached the surfaces and then used those surfaces to extrude(cut) the holes again.
