I'm trying to run an old Solidworks CAD program on my Win 10 Pro PC.
It installs ok and starts up ok .
I can open a new part drawing and place the 'line work' but as soon as I try to extrude the line work the program goes non-responsive, crashes and closes completely.
I've tried running as administrator, tried all sorts of compatibility modes from XP SP2,SP3 onward through W7.
I have an old Windows 7 machine that it will run on OK.
I've had a look for any graphics related settings in the program without success. Same with googling for a solution.
Any gurus have some suggestions as to what I might try before I give up?

Thanks
