Pre-Creo 3.0, our convention had been to change the appearance of the surfaces of ECAD features to a color that was 75% transparent. That way we were able to quickly distinguish between "known solid" geometry like the PCB & the volumes containing "possible geometry" like the ECAD features. But now we're unable to make the ECAD features transparent in the new releases.
The request is that you offer the option to make ECAD features transparent. Thanks for considering.
