Usable solid modelling apps based on OCC?

Hello, OCC looks like an extremely capable API, but unfortunately my company needs a traditional solid modeler. (We currently use Pro/E.) Are there any OSS or commercial packages that are made with OCC that are polished and have enough features to be used in a production environment? In other words, feature-based parametric solid modelling w/ assemblies and associative 2D drawings? Thanks for the help!
