as your mentioned for the problem regarding Auto CAD can't running by your computer becuase it can't support this software and this work.
I reccommend you should have a powerful computer for working with this software.
Please talk to your Mgr to prepare the budget plan in next year for order 1 CAD PC to support this problem.
If all people are accept. I'll contact to purhasing and send you the specification and the price.
Thank you,
