For instance, can I import the CAD files (dfx) provided by the manufactures ?  Would it infringe their license or forbid later redistribution ?

You would need the manufacturer's permission, most ' free/ symbols/block etc. have a free licence state, something like Creative Commons.
For info see here:

If you have any 'Free' blocks you can always post them here in this forum:
