I think Itoo's macro's are going to be fine for what I want to produce. I want to produce mostly screens/facades, mid-rise/high-rise architecture, paving patterns, custom furniture, etc... I'd like to learn how to create simple objects/elements and then tweak them with the built-in Itoo arithmetic macros to create customized paneling/patterns. Most likely I phrased my inexperienced question incorrectly.
Thanks for the assistance!
