Radial Profile

[Wingman]

I am running PC DMIS 3.7 MR 2.
I have need to report Radial Profiles in a big way (most every part I do needs this). Unfortunately, I have not found a way to force PC DMIS to report in Polar Coordinates. That leaves me with only three options I can think of.
1) Report normal Profile and calculate the radial displacement for the points. 2) Meaure the points as Individual Vector Points.
3) Measure one point and Loop 35 times

Neither of these are completely acceptable as I typically need to report every 10 degrees. Without a model that requires me to rotate my alignment 35 times and takes 25 individual points etc etc. Loops suck because I cannot find the points OR the alignment after the loop has completed.

Does Anybody know of a better way to do this?

Thanks,
Bill

have you tried paste with pattern with angular increments. then report your edge/vector points in T for the profile of each point.

[Wingman]

No. Paste with pattern is foreign to me. I have SEEN it done once or twice but have no idea where or how it is used.

For paste w/ pattern, go to edit, pattern, enter your angle increment(sounds like 10 degrees in your case) and the number of times you want to repeat it. Then highlight and select the feature that you are wanting to repeat, right click it and select copy, put the cursor after the feature, go to edit and select paste with pattern, then it will put all the points in for you at the 10 degree increments. TADA!

F1 will tell you how to use it.

Yes, paste with pattern works rather well in alot of cases, as Mark stated that is really almost all you need to do to make it work. However, you must keep in mind that when you enter an angular increment, that it will translate about the origin, so if your feature has a center point that is not part of the alignment, make sue to set an origin there or you could have points in alot of places you don't want them.

You can always do a linear open/closed scan to acheive what you are looking for as well. Simply calculate the max increment in inch/mm units that would equate to 10 degrees on that radius (i.e. 1 inch radius = max increment - .1745" = 10 degrees) and then generate the scan to points. Then you could just use T deviations for everything or even use the polar radius function and just set your +\- tols as bilateral profile tolerance.
