How can I have a bolt hole circle call out on a drawing?

Re: Bolt hole circle on drawing
Do you want to dimension a pitch circle diameter on a drawing?

If you have placed the holes radially, perhaps as a pattern, then you
can just show dimensions to see this. You can't create a dimension on
the radial centreline through these holes, if you want to use created
dimensions you'll have to make a daum curve / sketch throught the hole
axes and dimension to this.

You may wish to restate your question more clearly if this is not an
answer for the question you thought you asked.

I have problem with this as well, so let me add my question, maybe this
is what Brooke wanted to ask: How to make a pitch circle on a drawing,
maybe for having possibility to put a dimension on it, or just to show
that items are spaced on equal pitch?

Well, I agree with John Wade. The trick is to have a bolt circle hole =
pattern to call out. I also agree that there are more way to do it =
incorrectly than correctly and that you must start with a radially or =
diametrally placed hole which means you need something to measure the =
center of the radius/diameter from (an axis) and something to measure =
the angle from (a plane or planar surface). With a radial/diametral =
hole, you can pattern it by the angle. I think that's about all to =
achieve the bolt circle in the model.

To be able to call it out or 'show' it in the drawing, the detail file =
(.dtl) needs to have the bolt circle option enabled. Set=20
radial_pattern_axis_circle = yes which means it will show the radial =
axis and show the radial/diametral dimension on the axis circle. Also, =
with Show/Erase, you should get the initial angle and pattern angle and =
all the other hole properties. Nothing else will give you all this =
information with Show/Erase, although there are ways to fake in a radial =
pattern of holes.

For the most part I've just expanded on what John Wade said. But I'll =
