Hi JacobMag, I'm not 100% sure I understand the question.

Are you talking about clicking on the live view when programming your feature (which is then measured with Automatic Target (auto edge detection))? You can click anywhere on the circle when defining it, although the more spaced out the "hits" are, the more accurate our estimation of the circle will be. You can also double click on the circle in the live view, and it will define a target for the part of the circle in the Field Of View. You can then edit the start and end angles in the auto feature dialog to turn it from an arc section into a full circle.

Or are you talking about measuring a circle in Manual Target (crosshair) mode? If so, when you program the feature, you can drag the position of the targets around the feature to be where you want them to be measured at.

Or, are you saying that at execution time, it takes too long to go around the big circle taking lots of hits automatically? If that's the case you can try a few things :-

Measure the feature at a lower magnification
Ensure your target bands are only as wide around the feature as neccessary to ensure you find the correct edge. If they're bigger, it will take more processing time.
Use Specified Edge detection method if the edge is not noisy (it's quicker than Matching Edge).
Split the donut target into sections (right click on it and say Insert Target). Then, right click on the target and set it to Point Density "None". Do this as many times as you need to section off different bits of the circle you're not interested in. In a future version, we plan to make it easier to do this.

If I've missed the point of the question, please give more information.

Thanks for your input!
