Can I ask what it is that you are doing? Reason I'm asking is because I'm in school to be a mechanical engineer, and at work I draw up programs and occasionally design on AutoCAD but no 3D stuff yet just 2D.
Are you trying to mount a LS motor in something using existing holes in the front and back of the block? I'm thinking a E30 is a BMW?
I am indeed mounting an "ls" into a BMW. A 1986 325 to be exact. The factory engine mounts are on the front subframe and are notoriously weak. Using a solid front plate mount will do a couple things for me.
1. Avoid using the weak subframe
2. Avoid having to find a special header setup to fit around the mounts and steering linkage
3. Allow me to use the current steering setup, hopefully.
4. Mount will act as a brace and help stiffen the car.
I use Inventor Pro for all my drawings/modeling and I can do stress strain analysis if needed. The plate uses existing holes in the block and getting the dimensions correct is critical if you want it to fit without a ton of work. I picked the parts up Friday and they fit like a glove. I need to do a wee bit of grinding to clear gaskets and the driver side head. I'll try to snap some pictures soon of the finished plate on the engine but I do have one picture I took real quick.

Finished up the belt routing. I had to have spacers made to fit behind the alternator and the tensioner to line everything up. The final combo ended up being a Corvette water pump, F-body dampener, Corvette tensioner, and the trucks original alternator. I re-used the truck accessory bolts for the alternator and shortened two bolts to use on the tensioner.
I'll reinstall everything in the car and tack weld the mounts in place on the plate. Remove the plate and finish weld it followed by sand blasting and paint.
I also took the opportunity to pick up some 1.5" DOM for the next part of the project.
make sure to die grind the water jetted edges. the garnet cutting media gets embedded in the cut edge and will contaminate your weld making it porous and prone to cracking.
