[FIXED] Vehicle Prototyping creates generic Chassis with 0mm length and width

[bschneider]

This happens in 2nd Gear, version 2.1.0.2 when designing an engine. Substituting one of your chassis works fine. If you substituted a chassis, then go back to generic, it will use the length and width of the chassis, and a weight of negative hundreds of millions of kg. Same happens when designing a gearbox.

Generic versions of engines and gearboxes seem to be generated correctly though.
