Unfortunately drafting jobs have moved to China and India along with the manufacturing plants. Pray for Trump to win in November because he is the only one who has talked about re-negotiating foreign trade in a substantial manner, with America first in mind.
Best luck to you!
Engineering, design and drawings are mostly done in the U.S. if the company is a U.S. based outfit. All military contractors and companies making what could be dual use items (military or commercial) do all the engineering and manufacturing in the U.S.
No U.S. company wants China to get their grubby mits on the intellectual property that easily.
