Profile tolerance for an array of slots 3

[kkeenn]

I have an array of slots that are defined by basic dimensions (Radius, length) and a profile tolerance. I would like to dimension and tolerance the pattern but am not sure how.

If it was a hole pattern I could write 300X .25+-.004 with the attached positional tolerances and basic dimensions identifying the pattern. How do I add a profile tolerance to multiple features?

Ah, my apologies flash3780, I thought it was fsincox who posted the reply with link to Tec-Ease's tip. Or maybe you are Frank too?

Haha, no I'm Chris, but you can call me Frank if you want to.

I believe that the method that I referenced from Tec-ease gives you a lot of flexibility in the application. If your slot is interfacing with a bolt or a pin, a MMC modifier can be added to the positional tolerance. If your slot is a vent hole, you can allow the position of the holes to vary significantly, but control the profile/flow area more tightly. As was mentioned previously, the best implementation depends on the application.

Gordy,
It cannot be repeated enough, the functional requirements are the key!
