Going for a CAD upgrade

If you’re an experienced 3d modeler in any profession, you rely on certain tools. Being such an open source nerd, as well as just cheap, I depend on plenty of free tools.

Professional 3d modelers spend their careers keeping up with the tools that are in demand at movie or television studios which makes most of them scoff at free tools because of their simplicity or feature set.

But a key component lacking in entertainment work is dimensional and engineering accuracy. You can animate the universe in Maya and make it pretty, but good luck getting an accurate engineering visualization out of it.

And that’s something I looked for in other 3D CAD tools lately – sure the Hollywood boys an girls get all the glory on screen. But I’ve said this before since getting into 3d printing – NONE of the models usually made for the screen translate seamlessly to the printer. The demands on either are are very different.

There’s is some shared space between them in the concepts of creating profiles, polygons, extrusions and the like. But the meat an potatoes of creating something that actually works when manufactured? New ball of wax.

Dimensional accuracy, tolerances, the Shore scale of material usage, material density to weight ratios, etc. There’s so much more to worry about when turning a 3d design meant for actual use in the real world than there ever was in merely making something pretty onscreen. I take it back, but only a little – we’ve all worked for THAT director at some point. The one that things the weight of the world depends on THAT ONE PIXEL.

If only they knew.
