Why does my model not the normal grey shade?

[yaabro]

Don't know why my model is a see-thru orange and not the usual grey solid model color?

Any help?  Thanks.

Because it's not a solid model.  You revolved it as a surface model (possibly by accident).

In Inventor 2022, see the surface option you may have left on:

Toggle it off to extrude a solid.
