Which is the direction, I thought you and ABX were heading.

Last time I looked, ( this is from memory; accuracy not guaranteed) about 49 EU
or 75 USD

No it isn't scriptable, so the utility would just be a way to get a good start.
I find modeling utilities convenient to start with, and fine tune things later
with the text interface. Particularly for meshes, pathces, and splines. Oddly
enough, I don't use them for scene layout though, just specific objects.

Kind of like the idea I'm about to post. Maybe some will find it useful.
