Need Help on print
 

I drew up a print for a fixture that will be used to hold a separate
inspection block at 3 different fixed angles.
The fixture is a single aluminum block with end-milled out channels to
the 3 respective angles.
I am unsure as to where to reference the 0 from for the 3 angles, can
someone help?
Drawing is here (pdf format, about 12KB): http://www.pinwerks.com/fixture.pdf
Thank you in advance.
Marcel

If you mean how to locate the slots in the x and y directions,
dimension to a corner with a note that says, "DIMENSIONS ARE TO
THEORETICAL INTERSECTION." Then place a circle tangent to the adjacent
surfaces that represents a gage pin. Dimension the diameter of the pin
and place reference dimensions to the OD of the pin that can be easily
checked by the machinist or inspector to be sure that the feature is
in the right location.

For example:
