[LDCad] Idea for an LDCad script

[Owen Dive]

Better still, calculate the two lowest points—such as two wheels that are not quite in the same plane—and rotate the whole model so that they both rest at Y=0?

You could even do that for three points!
But depending on the geometry of the model it's possible that after such rotation, none of those three points will be the lowest, which might not be what you want.
