How to Measure Dimensions from Scanned Arc?

[[Se...]]

Hello, everyone!

As you can see in the image, there is a short arc section, about 38 degrees.

I want to know the dimensions of this arc.
Right now, I’m managing it with a profile curve, but I still need the exact dimensions.

Is there a good way to measure this accurately from the scan?

Also, I want to find the highest radius (R value) in the scanned area.
The scan was done along a curve path.

Any advice would be appreciated.

Thank you.

If you don't need profile or detailed view, then don't use curve.

Problem is that on this small angle you can not have exact measurement. Because of small angle you have a big uncertainty.

Do a few measurements and look how much it differs on a same part and same spot. For controlling dimensions it's more practical to use points.
Depending on size it can be from 5 to 7 points.

You can use Max characteristic to show maximum value from selected circles or you can use other Max something which will give you highest point from curve for given axis.

If you need better tip, then please share your tolerances, size and angle coverage. Perhaps more describe what you meant by "Also, I want to find the highest radius (R value) in the scanned area."

Thank you always for your support.

Please find the attached photo.
The tolerance is ±0.015, and the angle range is 38 degrees.

The arc serves as a master.
From the scanned section, I need to determine the point with the largest radius (R value) relative to the center.

Thank you again for your continued support.
