Hi my friends , I wrote a macro to make a coincident mate between twi components in assembly.After that , I tried to  check interference  and I got the volume of interference. my question is how can I evaluate the acceptable volume of interference value ( Vacc) that can make the coincident mate possible  ? it means if the volume of interference is bigger that this Vacc then , we consider that there are an interference between componnets ! else  no ! ... Thank you very much
