I'm new to SW. So maybe my question is stupid.
Now I meet a problems. I've made an assem as the attached image (bar.PNG ). I established some coincident mates in all the circular bar connections. The model I made is foldable.
But when I established a new assem and inserted the model I made as mentioned, I cannot drag and expand the model. The model was not fixed. So, I don't know how can I expand the model after insert it into a new assem.
Thank you for your help. I'm looking forward to your reply.
