I used the "Smart fasteners" feature to get all fasteners in place and saving much time.

I started a simulation analysis but an error message appeared saying that i have so many components interferences.

The interference detection results saying that all my bolts and nuts made automatically with the "Smart fasteners" feature are interferenced..

The picture below will explain more about the interference problem :

i tried to mate the bolt with the nut using the mechanical mate "Screw" but it doesn't give me the possibility to select the thread schematic of the bolt.

I'm really confused !

Any help please?
