Dimensioning a drilled hole on a curved surface

[BodyBagger]

Hello all,
What is the best way to dimension a drilled hole on a curved surface? When I try to dimension it on the drawing it does not pick it up because it does not see it as round (because of the curve). I hate to put an annotation with an arrow because there will be no auto updating if the size changes.

Thanks,
BB

I have to assume you are trying to dimension it in a view that is not on a plane perpendicular to the axis of the hole and not using autodimension because there should be no issue selecting the diameter in a view that is normal to the axis of the hole (or parallel if it was a revolve cut).

Depending on circumstance and necessary clarity I create a hole callout from a view normal to the hole axis using a depth indication (which should update with the hole if you use the hole wizard instead of an cut-extrude) or create a cross section thru the hole and dimension it from the cross-section view.

If that doesn't address your problem, can you show a picture of how you are trying to dimension the hole?

BB Put in an axis line on c-line of dia of hole in part. the ends of the axis can be dimesioned also at part level. That should cover most linear dims.

I am sorry, I should have mentioned that I am trying to dimension the diameter and not the position.

Thanks

BB,

A couple of questions:
1. Did you use the Hole Wizard to make the hole or did you make it with a standard extrude cut?
2. Do you have a view in your drawing that is the same normal view of when you made the hole? This is important to get the Hole Wizard callout to display and it is important to show a dimension from an extruded cut.

See Attached: I created a sphere with 4 holes in it (created in different ways) and have multiple views showing the diameter dimension. What are you doing differently?

Unfortunately, most people here still use "Extrude-Cut" to make holes and they refuse to change their ways. With that being said the hole was created with extrude-cut. I may just go and change it to a hole wizard feature to make life easier but I have been told to stop changing things if they are not broke. Attached is a pic of the part and feature.

Please post the part and drawing file. You'll get the fastest answer that way.
