offset line?

[[Ma...]]

Howdy, complete newbie here. Just got our Contura with the Vast XTR probe. I have zero experience in calypso, I have this part with 6 "ears" (highlighted in red) all have the same ID diameter, I want to measure the diameter of the 6 ears in relation to a bore. How would i go about creating a strategy for measuring the ears? I've attached some photos.
Thanks!

If it's applicable, then use circle if you want to report just radius/diameter or simple position.

Then i am not sure, but you probably can do cirlular path for one ear, then pattern that path. If path ( strategy ) cannot be patterned, then paterrn whole feature.

Or if you have a time, then make all circular paths in one feature by looking at model and calculator to get right angle for start and end.

Never ever measure this as a cylinder because of the diameter/length ratio. The simplest method is a circle with six single points.

I would agree with David that this shouldn't be a cylinder.

Perhaps I am interpreting this differently, but do you want this measured as 1 big circle, or as 6 smaller circles? If it is the former, then what David said about the 6 points makes sense, though you can still do it as 6 circle segments (you'll just have to play with the start angle and angle range in the strategy).

If the latter, you will definitely want to scan them, and run it pretty slowly. Also, you may need to constrain the position of those circles (in the evaluation button inside the feature) because you are unlikely to get a repeatable diameter/radius with just a small circle segment.

I'm trying to measure it as one diameter. The way I've gotten it to run so far is "Extract features, select one of the ears, then circle path with tangential turned off and adjust angle range."
I'm not sure if this is a crude way of doing it or not. but id assume there's a better way of doing it.
When I go to add XY constraints in the evaluation tab I get error "combination of the restrictions for the feature calculations not allowed"
Filler/outlier, normal vector, radius, gauge correction is unchecked.

From what I see on your screenshot, you are checking this as a cylinder. Try checking each "ear" as a circle. I believe (and I could be wrong) the reason you got the error is you are checking it as a cylinder and a full 360 degrees. If you check each "ear" as a single circle, you will have much better luck with the constraints.

Because you are checking it as a single diameter, you should not need to use constraints.
Be sure to use filters and outliers, and verify that the form of your feature looks good to ensure that you do not need to adjust your scan paths.
As others suggested, you may want to evaluate as a circle, instead of as a cylinder.
You can simply pull down a circle feature, and recall feature points and select the appropriate paths.

Can't really add too much more than anyone else has said I think. Looks good, except that it is a cylinder. I would definitely measure it as a cylinder. It might work fine for diameter/radius, but if you want location (and certainly orientation), it's not going to work too well as a cylinder.

got everything figured out, changing from a cylinder to a circle drastically reduced my radial runout. much better. Thanks for the help everyone its much appreciated.
