Hello, everyone.
I am the sblano ing.meccanica in polyba.
I am at the first steps in using catia v5r21 and I have a small problem that I hope you can explain to me.
My prof. provided us with a package in which there is a set of an electric vehicle.
my task is to design the missing parts and model them, only that everything is blocked and not editable. . Can you tell me how to do this?

from the image looks like an imported file (step?) and there is only one solid, so the various phases of construction are lacking
