The designware we used, called SolidWorks, simulates in 3d, thus you can
make an entire machine function in a virtual world, before it's built and
tested in the real world. Yes, not all designs are virtually fool proof.
But it's a lot closer to working than designing on paper and then
building, only to find out that your design has an error big enough to
make it inoperable.

I've been on a tour of Edelbrock Inc (remember Vic Edelbrock?) and have
seen designs of intake manifolds, heads, headers, etc., in the virtual
world of the software they use. In the case of heads, there are many
things that have to be controlled, such as the placement of intake/exhaust
runners to get the performance they want in any product. Once designed and
actually made, they're tested in the dyno rooms in the real world.

Old School, these days. Of course, it helps that the person doing the
virtual designing has a few years of design engineering background.
