Hi Ali,
I cannot seem to reproduce the behavior. Are you using 3D Connexion device?
Many thanks!
Can you post the file?
Thanks,
Scott
Hi Ali,
I suspect some of the issues you are encountering might be related to 3D Connexion. Based on the following thread, a user contacted the vendor and found out Inventor 2018 is not yet fully supported. I cannot say it for sure that all your issues are related to this but the fact that we cannot reproduce it in house seems to indicate the case. I will work with project team to understand the issue better and also we will try to contact 3D Connexion to confirm it.
Many thanks!
