Hi I am making a bolted assembly, normal bolts are fine, butthese countersunk ones are a pain. I made little countersunkinserts to sit in the holes to give a flat surface. Now the errormessage comes up saying 'Source surface not defined in SL1 file atbolt Conn. ID7'
I supressed bolt conn 7 and even deleted it remeshing each time,but no use. What is an SL1 file? any ideas of what might be wrong.
