Proper composite callout for this?
Proper composite callout for this?
(OP)
Is this the correct way to GD&T this?
The dowel hole must have a tight positional tolerance to the center locating ring, and that it is in this orientation to the indicating edge (-
of the fixture. The indicating edge has to be orientated tightly horizontally to the pattern, but can have a larger positional tolerance in the Y axis.
Thanks

The perpendicularity callout is missing a diameter symbol, or a reference to datum B if it is orientation sensitive.
Is the XY indicator at the lower left supposed to be related to the view calling out the locating ring?

Ignor the cad interface axis. It is part of the cad system, not part of the drawing.
Any suggestions on my actual question?
RE: Proper composite callout for this?
The indicating edge needs to be controlled because the machine operator uses a dial indicator to square up the fixture on the cnc machine.
The critical part of this fixture is the center locating ring and the dowel hole location, and that the indicating edge is orientated to that pattern as shown.
So I want to control the "orientation" of the indicating edge to the pattern, but have a large freedom of location of that edge in the y axis.

How can I tolerance the orientation of the edge to the dowel hole and datum c without having to use a note like this?
Hope this helps
