1. OpenGL is open, direct X is not.

That's obvious. How does that matter?
Yup, a proprietary graphics standard will allow a monopoly to dictate
what platform CAD runs on. Right now there is a choice.

2. OpenGL works on any OS

Does Solidworks? Neither does any other CAD program.
Several OS support serious CAD.
Unix - CATIA, UG, Pro/E, and perhaps some lesser known
Windows XP - The above plus mid range modelers and AutoCAD
Windows NT and 2k - Ditto XP but only older versions.
MaxOS - SolidWorks, and others (don't know if they use OGL or
something else)
Linux - Pro/E and others.

3. There is a lot invested in the hardware

Which will all be obsolete three years after purchase (in other words
"invested in hardware" is not a compelling reason).

I invest in high end graphics cards with a much longer time horizon
since at least as far as SW is concerned it only takes a CPU and
motherboard upgrade to keep up at minimum cost.


4. Work and devlopment doesn't always translate into performance and
stability.

True but then when you have more people working the problem you're
likely to get it right sooner.

If it ain't broke, why fix it? What in the world is wrong with OpenGL
as far as CAD is concerned? I have yet to see a post on the NG
complaining about graphics issues other than driver problems.

If it is MicroSoft throwing people and money on the problem don't bank
on it. They haven't gotten the OS right yet and it has been 14 or 15
years since New Technology (NT) was going to save the world from Unix
and MAC.

SW got it right when there were very few people working on the
problem. The bigger they grow the more problems there are. Getting it
right doesn't always scale with the number of people working on it.

5. There is no perceived need. Can directX make drawings faster? Can
it shorten rebuild times in drawings and large assemblies?

Neither Direct X or Open GL are going to do anything to speed up
rebuild times.

If it ain't broke don't fix it. SW is moving away from letting the
graphics card do all the work anyway.
