Hello all. I have this assembly. As you can see there is a external thread on the bottom element. The internal thread is in the top element. I created both of these parts with the same views in mind starting the helix from the same plane, same side, same angle. How do I know they are aligned correctly so that the circle in the bottom part is inline with the hole on the top part? Is my technique that I mentioned enough to ensure this? I am about to 3D print a part and just didn't want to waste to much time trying to figure it out. I read the other forum post on something similar it was kind of strange for me to follow. Any help is greatly appreciated. Thanks in advance.
