I hear you. But as we all know it's been a ripe area for disruption since the 1970's. :) At the moment it's less to do with software as it is to do with the way we share the resultant information, of which there are emerging international standards. MCAD is not my speciality but I don't think I've seen a standard for handling parametrics. Unfortunately closed standards are hard enough to get governments and industry to adopt let along open ones. If you want a solid object modeller with parametrics that's open source and you can compile yourself, check out BRL-CAD.
