I think the basic problem here is that a rendering / animation package is a HUGE project, and a modeler / CAD type app is another HUGE project. Either of these is quite a bit more complex than most other kinds of apps on the market.
Having one company do BOTH requires some pretty major resources (even doing one of them does). EIAS is what EITG does, and does well. They have a long history and quality they are building on. Doing a modeler really isn’t their speciality. EIM was cool in some ways (Ubers for example), but IMHO quite lacking in its tool-set and workflow. I think this is just a matter of resources and this not being their primary skill set.
I use Concepts Unlimited, and feel the same way about their rendering implementation. They are experts at modelers, but the 3D/rendering part just doesn’t have the feel of a dedicated rendering package like EI.
Sure, one can get good results out of CSi’s rendering app… and for industrial designers that just need a few conceptual renderings… they might really love the built-in ability. Same for EIM, some great stuff was done with it, and was nice to have it right in the EI package (though not really built in)… but it just doesn’t match the dedicated modelers.
So, I voted for building a few modeling tools into EIAS, but leave the job of a real modeler to a company focused on doing it at a high level. Otherwise, you just end up with a mediocre product, and the primary app suffers a slow-down because of resources.
