How to line up shapes?

[akent31]

Hello Guys! I am relatively new to Auto CAD and this is my first time using it for 3D Printing. I want to line up these two shapes so that I don't have to make two separate files to 3d print and can instead print these together at the same time. How would I go about this?

go into top plan view and align one on top of the other.

If you do that do they stick together?
