Hi andras, that's an interesting idea!

Kind of similar in some ways to SketchUp's "components" mechanism.

But the system that you show there with all kinds of "vars" would probably be kind of restricted to a smaller number of predefined objects that had been basically programmed/scripted to work off those number inputs.

Systems like that become really easy to work with those predefined objects, but then what happens when you want to make your own custom object?

MoI is kind of overall more focused on being able to more freely create shapes rather than being kind of "locked in" to only working with assembling a small set of predefined shapes.

So that's why what you show there is kind of not quite aligned with the overall structure of MoI, at least not currently.

I do want to extend history in the future though, which may help to give some similar functionality to what you are showing there. But I'd like to do it in a more generic way where the "wall" for example does not have to come from a specifically coded script but instead just remembers a sequence of modeling commands that you used to build it. That would make it easier for people to make custom shapes without being dependent on a script programmer to create such things for them...
