How does Creo (using Creo Parametric 3) handle accuracy. It confuses me that there is a relative accuracy and an absolute accuracy. And that relative accuracy seems to be the default.
Also having some issues with imported parts. Our workflow is this:
- Part designed in Catia (Catia global tolerance set to 0.001mm) and saved as CATpart.
- Part imported into Creo for mould/jig design but Creo states that accuracy is now 0.05mm. Setting the accuracy finer (back to 0.001mm) results in part being converted from a solid to a surface due to (usually very many) naked edges. File needs to be extensively repaired to continue work in Creo or work is continued at 0.05mm accuracy.
Why is a part accuracy changed. How does the change in accuracy impact the design as a whole?
Thanks
