Help needed with strange thing after opening part

[liam41999]

When I opened a part I made yesterday, this strange thing (see attachment) came on the part and I can't get it away by disabeling in the object visibility command. It also appears in an assambly.

I'm also using Inventor 2020.

Hi try this (for part and assembly both):

1. Open affected assembly
2. Use command "Rebuild All"
3. Use command "Update Mass"
4. Save assembly and all references
5. Close assembly and all open files
6. Re-Open assembly

Can you Attach the file here?

That is the center of gravity icon.

With that part open go to the "View" tab in Inventor and in the Visibility section see if the "Center of Gravity" button is selected? If so unselect it.

Inventor has had a bug in recent years in which the center of gravity icon turns on unexpectedly and in some cases cannot be turned off.

The steps that @admaiora  posted have sometimes helped to fix the issue so if your center of gravity is on and can't be turned off then try those.
