How to iterate a secondary alignment?

[[Jo...]]

Hello,

I have a part with datums ABC, which I want to represent as an alignment (call it Alignment1). A is a plane with several circular target areas, and the target areas are positioned relative to B and C. Can someone explain to me how to loop the alignment so that the target areas are measured in the correct locations relative to the B and C actuals?

I know how to do this for the Base Alignment, but I can't figure out how to do it in a secondary alignment.

Thank you.

Right click on the alignment and choose loop. Right click in Break Condition
and choose formula, enter it in the space directly under Boolean expression.
Then click insert and enter (in the space named "END") the number of times
you want to loop it.

differenceSystem().valueA<0.0005.

Hi, thanks for the response. I have a further question:

Using this method, the measuring strategies for Datum A will still be referenced to the Base Alignment, correct? For example, if I use a Circular Path, the coordinates of the path will be relative to the Base Alignment instead of to Alignment 1.

When looping the Base Alignment I understand this is not a problem, since the features used to create the Base Alignment are also assigned to the Base Alignment.

But for features used to create Alignment1, I cannot make the assignment also "Alignment1" (I assume to prevent a circular reference).

Do you know what I mean?

Use formulas it will override the base alignments.

I am also interested in a solution for this problem.

I stopped using looped secondary alignments for the same reasons Josh Gratz described. They don't behave the same as a looped Base alignment. I'm forced to "manually loop" by building out features and alignments for each iteration of the setup.

Danny H is right. You can use a formula for X and Y on each circle path.

Ian, I'm not sure what you mean.Can you give me an example?

I guess I don't understand how a looped secondary alignment can be useful if it's not recursive for lack of a better word.

I wasn't commenting on the looped base alignment, just that you can ensure that you're hitting the datum targets relative to datum B and C (as opposed to the base alignment) using formulas.

You can do that for each circle path. Just offset by the basic dimension.
