Dimensions in looping?

[gopher]

I have a part with 24 equally spaced slots around an outer diameter. I could have used a pattern for this example, but I have other situations where a pattern would not work.

While the loop works just fine, what I was hoping for was that the the loop would perform the allignment rotation and all my dimension would report the true nominals and not adjust like what happens when you use a pattern.

example: the 15.22 dim in my code below is just a radius taken on a 30.44 diameter which is done 24 times around the part. I would like the nominal to report 15.22 for each point and not change. Can this be done?

I hope I wasnt too confusing with what I was trying to say.

Version of PCDMIS being used?

[gopher]

its pcdmis 3.7 mr2

Anyone? No answers? Surely Im not the only one that this drives nuts.

1) for the radial point you could use a R instead of an X...

2) I think you have to incorporate a coordinate system rotation in the loop. I did this not to long ago and the angle in the loop is for changing the feature locations but not rotating the CS.

Try this

Mm=0

V6 =loop/start, Id = Yes, Number = 24, Start = 1, Skip = ,
Offset: Xaxis = 0, Yaxis = 0, Zaxis = 0, Angle = 0

A1 =alignment/start,recall:autoalign, List= Yes
Alignment/rotate_offset,(mm*15),about,zplus
