Created a SE part from a STEP file.
Trying to insert this part into an assembly - part does not appear on the screen.
Tried activating and showing hthis part - NG
Nothing appears on the screen
Go to Solution.
you imported part is most likely a construction body (surfaces)
in assembly RMB the part then show/hide constructions - check on surfaces.
In part toggle from construction to design body or attach the construction thus making it design...
