I have a reference part I want to show in my drawing file(asphantom lines) without hiding the underlying parts. ( I want toseethe underlying parts as if the reference part wasn'tshown). I thought I have done this before in SOlidworks, butcantremember or find how right now.  I know I have done itwithother software, but I really want to do this one in solidworksifpossibleSolidworksDrawings And Detailing
