Has anyone used j-link to analyze dimensional tolerances for an assembly?
We're currently evaluating several assemblies and the tolerance values of several components in each. Basically, I was hoping someone has already developed a tool (we use Creo2.0) that can open an assembly and perform a Monte Carlo type analysis of the assembly using all of the dimensional tolerances. I know there is a tolerance analysis tool built into Creo, but to my understanding it is only a one dimensional loop, I would like something that had the ability to evaluate the full six degree of freedom nature of the rigid-body parts.

A company called Variation Systems Analysis, Inc, did this a couple decades ago, but they are now owned by Siemens. They used to directly embed their analysis setup into the Pro/E model.
Unlike most analyzers, VSA allowed form variations to be accounted for. Some just regenerate the model to produce the sensitivities. VSA created their own mesh and used first principals analysis to generate a Monte Carlo simulation along with the same sort of measurements made in inspection. Since the analysis was externalized, one could hook any geometry related calculations, such as compression ratio, into other analyses, such as combustion calcs.
VSA was pretty sweet, but not as sales-demo friendly as TI-TOL/CE-TOL/BYU via Adcats/Kenneth Chase.
