Radial dimension on circular contours

[Ross.GroatG9LKA]

Hello

I'm having an issue with automated dimension style not picking up circular contours on CHS or tubular sections.

Using the exact same drawing style on an I-section, Box section or Channel the radius of the circular contour is displayed, however when I use the same drawing style on a CHS or tubular section the circular contour is ignored by the dimension request.

I've attached a screenshot showing an example. On the left the radial dim is shown on a box section, on the right the radial dim is ignored on a CHS even though the same drawing style was used.

Is there something I'm missing or is it not possible to get an automated dimension for the radius of a circular contour on this type of section? I'm aware I can add this manually with a parametric dimension if required but would like this dimension to be automated by the drawing style if possible.

Thanks

Ross

could you upload an example model?

is it both a contour or is one maybe a hole?

Hi Sebastian

Thanks for your reply. I've attached a copy of the model showing the example I used and a copy of the detail drawing.

Both sections have circular contours added to them, not holes.

I have tried using both my custom drawing style and the default Advance Steel Single Part drawing style and get the same result for both. The radius isn't recognised on the tubular sections (Could it be because it doesn't have a flat face/Flange/Web and so the dimension is being ignored?)

this seems to be a problem because of the circle approximation. If we create a round contour it will be projected to the outer surface of the beam. If you have a parallel surface to the contour, the dimension will work.

But if the contour is projected to a bended surface, the "circle" will be approaximated. And I think this is the problem for the radial dimension, because it will not recognize a regular radius
