Profile of Circle

[[Mi...]]

So I am tasked with finding Surface profile of a circle. We have a new Eng and he loves profiles lol. I have a bore that has a Diam Of 22mm and Depth of 7mm. He has added a surface profile call out of 0.1 to this ID. Never had to do it this way. Need guidance lol.

Do I go in, kick off some circles that I can flood with points then recall those points into a profile of a surface somehow? He wants the profile results from circles inside the Diam. Kinda scratching my head.

Is there a Datum feature called out?
I think a "Surface Profile" would need to apply to a Cylinder of multiple circle paths... I think a single Circle would need to be recalled in a Curve, for a Line profile(?).

You can make loop with circle or scan cylinder and recall just each path into one circle.

I'd section the model (assuming you have one) several places down into the cylinder and
extract curves, recalling them into a FFS. You can't do surface profile on a 2d feature (circle).

If you can not report profile on circle you can use another one callout - shape or what it is - it's under profile - looks like roughness

Form.

With that and resticting ( locking ) coordinates and radius you can achieve same thing and profile - but i think it will be without doubling value.

With Result Element.

getActual("Form1").actual*2

If you use the new GD&T Line Profile you can do 2d features like Line and Circle. 🙂

Simple if you have a cad model and free form.
open a free form element, go to "Recall Feature Points" and select the circle or several circles on that diameter.
now use that as you profile feature.

You can use this method to gather any number of Circles, lines, planes and points as needed

If the size is perfect, the roundness (minimum error fit) of a circle is equal to the profile, because the plus and minus radial deviations are equal and summed for the result. If the size is not exact, the min or max radial deviation farthest from the nominal radius is doubled to determine the profile.

Thanks all. Now that I am back in the lab I can look at all the suggestions yahoooo.

I do have FF and Curve as well as the Cad for the part.

Unless you want to use the new GD&T package, I'd just use Curve if it is a Profile of a Line.
