I am exporting a part as .3mf or .stl and it messes up the original model when I import it into my 3d printing program.

Any idea why this is happening?

The original model I have in the second picture did not add on weird features to my .3mf file.

I tried to export the part as .xb (parasolid) and then save it as .stl or .3mf and I still get the same error.

I tried to hide sketches thinking maybe that is the issue and still no luck.
