CAD for older computers

[RoboDesigners]

My first suggestion is to take the computer to BestBuy and ask them to put in more RAM if possible. (Or if you're the adventurous type, do it yourself.)

If you can get 512MB of RAM, you could try Google SketchUp. (sketchup.google.com/) It is totally different than AutoDesk Inventor (my only other CAD experience), but it is quite intuitive and great for quick prototyping...

Hope this helps!

It isn't just one computer, it is about 16 for a class. Also, I should mention Bestbuy is the absolute last place I'd take any computer. I'm trying to see if I can work with what I have before requesting upgrades. The machines are not in a setting where I have full control over upgrading them, but I am plenty capable if they were.

What type of CAD program are you looking for? Years ago there was something like Expert Cad or KeyCad or something that would run on really old computers (like the original Pentiums)

3d modeling software seems to be kind of expensive, and the folks who sell it don't sell old versions cheap or give them away, as far as I can tell.

http://brlcad.org/d/about BRLCad comes to mind. Sadly it has a pretty crazy learning curve on it.

That was my suggestion, too.

Why not just find some older versions of CAD software that will run on those machines. CAD is one of those things that learning the fundamentals even on old software will be better than nothing. Google sketchup, while it has it's interesting features is NOT an engineering CAD software with very few features that will translate over to a real system. I would rather run Inventor Version 5 than sketchup.


You might also want to check pro-e student edition, they did some things to lighten the software so it is capable of running on things other than $1000 work stations.

I agree. Sketchup is a great tool, but is not an engineering tool. It does lack many of the dimensioning, relation, and sketch and modeling tools of a real CAD program. I don't think it would be adequate for my purposes.

Inventor 5 is still a favorite of mine for simple and lightweight work. It'll run adequately on most computers from the last 7 years. The problem is, I don't think there's any way I'd legally be able to get licenses for Inventor 5.

Thanks for the tip on Pro/E. To be honest, I kind of forgot about Pro/E. It looks like they have a great school program. I'll definitely look into it, and it may be worth upgrading the computers if we can get better software at no cost.

I had been looking to see if there's anything that can get me by for a few months on these older machines, but I know, their time has past.
