So im wanting to make correct threads. My example is 5/16-18 threads. what ive been doing I found information on inner and outer thread diameter for the bolt. I set the outer circle to 0.3113". my inner dia is 0.2454". for a small reference i do (0.3113-0.2452)/2=0.03305" This tells me how deep the thread is from the top. The spacing I just figured its 18 tpi so i made a line thats 1/18". for the helix i did 1/18 and rounded up to 0.056" because if i just did 1/18 it wouldnt work
