Hi Psygorn,

re:

No there isn't a concept like that currently. But you may want to try the node editor to define your object as a series of steps which could be applied to different surfaces, that might fit with what you describe.

Just in general models that have a lot of repetitive structures in them are good candidates for building with a procedural mechanism like the node editor rather than a regular "drawing with the mouse" type mechanism like regular MoI operation is focused on.

You also might want to check out Grasshopper or Houdini which are focused on that type of thing.
