Mirror Options (Mirror, Reuse and Exclude) All Grayed Out

[xapex93586]

Mirroring a part in an assembly but all the mirror options are grayed out. Part is modeled, not imported, and saved to the desktop. Inventor 2020.

How do I enable these mirror options? Thank you.

Hi! The only possibility is that the assembly was saved in 2021 or later. And, you are opening it in 2020. Please share the files here. The forum experts can help take a look.

Many thanks!
