I'm trying to open a large .stp file (.65 GB), and SolidWorks 2018 seems to hit a wall trying to open it. I have task manager open and it shows the RAM leveling off around 10 GB (out of 32), and the CPU keeps churning at about 90% but the part loads indefinitely. It's been working for over 30 minutes. I've rebooted the computer, changed the sldimport.exe process to high priority, and tried B-Rep mapping but it's still hitting a wall. Is there any way to handle such a large file?
