When searching in the VRC knowledge base, I found, that it needs a full install of Solid Edge (API) to read the properties into the SWX PDM. Does anyone know ad hoc, if this is still the case in 2018? If so: does anyone know, why this is so limitated? 3D Interconnect reads native Edge properties into the resulting SLDPRT. Independend, if maintain the xRef to native PAR or if breaking the link and create unreferenced SLDPRT ... it would be extremely helpful, if SWX MCAD + SWX PDM would have the same level of intelligence and if both would correspond to each other, so that MCAD + PDM can be used together in a meaningful way :-)
According to the 2018 PR1 documentation, the full version of SE must still be installed to manage SE files.
I like what you are thinking, if SW can read these values without SE, why does PDM need it?!
