So after learning how to create annotations in NX, I took an old part that I created previously and added annotations to them. While the annotations were the newer subject, it was actually the easier part.
Creating the part itself was quite a bit of work. There were quite a few extrusions, sketches on the faces of the extrusions, some of the sketches needed to be converted to reference lines rather than actual lines, it goes on.
After all that was done, I used what I learned previously to add the dimensions to it. As a note, the circle with the line going through it means diameter, the arrow pointing down is the depth, and the units are all in millimeters.
