Reference model dimension for "PCD" in drawing callout?
Reference model dimension for "PCD" in drawing callout?
(OP)
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

RE: Reference model dimension for "PCD" in drawing callout?
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 21 in ASME Y14.5M-1994, or page 22 in ASME Y14.5-2009.
This easier to do in SolidWorks. Note everyone understands acronyms like PCD and BCD.
