Reference model dimension for "PCD" in drawing callout?

[arlenn]

I have done a great deal of googling for this, with no luck.

How might one reference a dimension used in model construction geometry for use in a circular hole callout.

eg:

<NUM_INST>X <MOD-DIAM> <hw-tapdrldia> <HOLE-DEPTH> <hw-tapdrldepth>
<hw-threaddesc> <hw-threadclass> <HOLE-DEPTH> <hw-threaddepth>
ON <MOD-DIAM> $$1.000$$ PCD

with $$ $$ represending a reference to a dimension in parent model
resulting in the hole callout displaying "... on 1.000 PDC"


This is SW2011 SP4.

Thanks for help in advance

arlenn,

As per ASME Y14.5, use the centremark feature in circular mode to draw your pitch circle. Apply a dimension to this. Convert the dimension to a diameter. Apply a dimension to the angle between the holes, and show the quantity of holes.

For examples, see page[&nbsp;]21 in ASME Y14.5M-1994, or page[&nbsp;]22 in ASME Y14.5-2009.

This easier to do in SolidWorks. Note everyone understands acronyms like PCD and BCD.
