I'm having trouble understanding 2 parts of this 3 view drawing. We're supposed to draw it on pro e.

1. For the top view drawing, the dimension on the right that says "2x45° x .25" What does the .25 mean? I calculated the depth of that part to be 1.32-1.075=.245.

2. For the dimension in the top view drawing that states "4x diameter .164-32 UNC depth .535." How do we know the depth of the hole? I can't find where it specifies the depth of the hole anywhere on the drawing?

If someone can help me out, I'd appreciate it. Thanks.
