I cannot select any feature other than planes to add constraints
Whenever I am bringing in a part to assemble, I cannot select any feature other than planes to add constraints. I can select and features form the parts already there in the assembly but not the part the just bought. The part is acting like a whole body
Check the Reference control settings for part which is not working, File > Prepare > Model Properties > Change Reference and backup > Check permission for reference creation or reference for placement.
