Recall Feature Points from a Single Circle Path of a Cylinder, High Volume (Loop or Pattern)

Very strange. I'm doing the same exact thing and it works just fine. 

I have tried it with 6.8.2002 and 6.8.24.

What service pack are you using?

I'm running 7.8.12, and I can access the formula option in the Recall Feature Points. @Henrik Lindahl, I think your idea is great and I'm verifying it now. Unfortunately, I encountered an issue where my cylinder list starts at "106" instead of "1". I'm not too familiar with the PCM coding, so does anyone have any recommendations on how to have the loop start at 106? I tried variable functions/combinations within the list formula, but I could not get the loop to start at "106" properly. Any tips? Should be fairly easy.

Also, what coding language does PCM most closely follow? C++, Java, Python?

Python is not using brackets like here, but also is using indentation to separate levels ( like for loops )
C++ and Java are using brackets, but you have to write full definitions if, then, else.

PCM looks for me more like a VBScript from Microsoft.

Do you have any gaps in your names or does it run uninterrupted from 106 to 2000+?

If you have an uninterrupted series it should work if you change "Cylinder" +LOOP1 to "Cylinder" +(LOOP1+105)

The brackets at important in 6.8 and I think it is the same in later versions. I'm not at my computer right now so I can't verify this but I think it will work.

Thanks, Henrik! That worked perfectly. I originally tried adding that "105" index outside the loop, so it makes sense why my combinations did not work 🤦🏼‍♂️. But I have my cylinder interrupted in quarters—cylinder 106 to 696, 3065 to 6025, etc. While 2000+ already seems like a lot of cylinders, the actual part has about 9000 total cylinders. We are only completing a 25% sample coverage 😆 super fun stuff! 

Due to these interruptions and my limited knowledge in PCM. I planned to have 4 different "CylinderX's" so that I could capture each segment. But happy to hear if you have any recommendations to account for the interrupted series in the loop, I'd be interested. 

I'm currently implementing your suggestion into my program. I will update you guys shortly! Great thinking on the formulas in each nominal for the CylinderX feature. I mistakenly thought these were highlighted in yellow since the recall feature points were a formula. Nice touch! 

Thanks again for the help so far!

Do you have PCM?

Is there any other cylinders in the program that you do not want to recall?

What the hell is this part containing almost 10k holes? How long does it take to measure? I thought my parts could be crazy with 1000-2000 holes but this is insane.
