Tolerances in Sketch, is it worth it?
Tolerances in Sketch, is it worth it?
(OP)
Just looking for some opinions on a Design Intent idea. I have never included tolerances in sketch dimensions, but I thought maybe it would be nice in capturing design intent and furthermore it would be cool if it automatically showed while annotating...
Just an idea, do you think it would be worth it?

I did and the tolerance from the sketch does not inherit onto the drawing. I see no advantage to adding the tolerance onto the sketch. I would change the dimension style on the drawing and add the tolerance there.

I think this is worth an enhancement request (and once again, perhaps it is already there...tell me how if so!), anyone else think it is not?
Thanks for your time,

You add the design critera to the model, not the sketch. Otherwise it will get you the same result.
Drop a view into a drawing, inherit PMI and voila... Drawing is detailed, tolerances and all.
I'm not sure what version PMI appeared in, but I use NX6 and it works there.

And if that wasn't cool enough, once you leave the Sketch task and you see that 'PMI Dimension' in your model, if you double-click on that Dimension, you'll be able to edit it (and the model will update) as if it were still a Sketch dimension (which in reality it actually is).

RE: Tolerances in Sketch, is it worth it?
Just a quick though on this. I have played around with "sketch to drawing" tolerances and dimensions before on another CAD system, and the problem I had was that you have to think ahead very well. Whatever dimensions you use on the sketch are the dimensions that you have to use in your drawing. So you have to be very aware of good dimensioning practices (ie. only dimension something ONCE and in its normal perp. view). IF you chose to use different dimensions in the drawing than you used in the sketch you have to be very careful with bonus tolerancing and on top of that you have to pay a lot of attention to you primary and secondary datums, at least more so than if you did all the tolerancing in the drawing. We are switching to NX6 soon ( I hope) and now I am rather jealous that we are not going to NX7.5 cause Johns comment was rather exciting (as far as an engineer can get excited...) but anyway, hoped this gave you some things to think about.
Thanks,
Rick
