I am one the users using Inventor 2021.
When I use inventor, I encountered very weird situation.
Every constraints are satisfied and there was no problem but in the screen some of display was not working correctly.
Can someone answer why this happened?

Hi Josh,

I am sorry that I cannot tell where the problem is by looking at the images. Please share the iam and ipt files.

Many thanks!
