Hi Brian,

re:

Yes, that's true.

Geometry factories are just one part of the whole system, like you wrote above a geometry factory is something set up to assist making commands. They are set up so that you can basically connect a UI control with a factory input ("binding") and then when the UI control is modified the factory will update and recalculate the result and deal with a bunch of things like deleting any previous results and restoring the original objects if the command is canceled and stuff like that.

That's quite a bit of stuff that many command scripts would need to do so it's helpful if that can be packaged up so that each command script doesn't have to those things themselves.
