cant copy paste jbeam parts

hello i cant copy paste jbeam parts. Not work

 

I want to put rally light and roll cage in a midsize

 

To do this you will need to add a slot for the rally lights and roll cage onto the midsize and then change the slot names of the parts to fit into the ones you created. Next you will have to add the mesh and materials files into a folder inside the midsize folder. that should be about it but you still need to manually adjust the positions of the jbeam and the mesh.

 

Thank

 

No problem buddy.
