Workarounds to use IDX for rigid flex assemblies with multiple thicknesses

Hi,

We're using Creo 10.0.6.0 and currently evaluating the ECAD-MCAD Collaboration (ECX) which allows using IDX files. On the ECAD side, we use Cadence. We ran into a snag because we have rigid flex assemblies that use multiple thicknesses, but Creo doesn't support that yet. Many references here:

We have workarounds to manage these files today using EMN/EMP transfers. I'm interested in learning if others have already found workarounds to manage multiple thicknesses with IDX files. 

Thanks,

Joe
