Tolerance Analysis

[Enginerd9]

Hey guys,

I'm diving into Tolerance Analysis and was wondering if there's any good tutorials or resources for some key tricks, etc. I've read the attached pdf, and want more since I don't have access to the tutorial files.

Thanks!

This is driving me crazy... for something tauted as "easy to use" it's sure got a lot of catching up to do.

Everything I've found so far is "weee! Look, ain't it purdy?!" I'm looking for "Hey, start here. Define your model/assembly like this. Then, define the study like so and click here, etc."

For example, I have a tube which is holding a pin. The pin has a notch in it. Now, the length of the tube, notch location, and pin location all have variations based on my defined tolerance bands. So, I want to "study" where the end of my pin and my notch location ends up with respect to the end of the tube. Seems pretty basic, really easy. But, of course, like learning anything else with ProE... I've equal parts dissapointed in the marketing of the module, and frustrated with the click efficiency.

Does anyone have solid information to help get this rolling? I've spent the better part of my day looking all over this site and others to no avail.

Thanks!

Have you looked on the Sigmetrix website?
I had the 1 week training class in it about 7 years ago, but haven't used it in at least 6 years. (Change in companies and them not having the module.)
The few engineers that started to use it had the opinion that it was hard to set up and they could do stack-up analysis by hand faster. While this may be true the first time, as with most things in CAD, it is the subsequent changes that get you the benefit.

Yeah, I could do the training if it was all that important to the company. As it stands, I'm looking at whatever I can find for free.

The one thing ProE doesn't do well is explain how to prepare your models or assemblies BEFORE going into their special modules. I'm discovering that there's a lot of pre-work required to make the models present the information in a way which the modules can understand and use. It would help a great deal if in their help files or tutotrials, they stopped assuming you already knew that and had everything set up and ready. It's almost a handicap, because I don't have the free-form design control I had before with SolidWorks... I basically have to know the final form of my part or assembly before I even get started so I create the features as necessary for the modules to all work properly, etc. It's quite frustrating and completely inneficient.

Anyway, so no training is possible. I guess I'm back to plodding through it until it works and makes sense.
