What is the largest stl an iges file solidworks can handle, every time I try an opening files it always says the files are to big? I have been using solidworks for a little over a year I am use to using UG. I have noticed this software can not handle HALF of what UG or Solid Edge Can. Is there any way to fix this or should we just look into buying other software that can handle the job we are trying to do. Sorry but after using this for a year I am ready to quit this job is only stressful because of the software I have never had even close to stress all because the software cant handle what I am Doing.
