Hm, I wasn't thinking about the implication of EVALUATE to mean whether the CSG recipe is evaluated, but merely to indicate what output formats to "evaluate" the input geometry to. You are correct, though, that it presently performs evaluated nmg and bot. You'd be adding unevaluated brep nurbs and Anurag will probably end up adding evaluated volumetric. > I'd like to keep the name "brep" instead of changing it to "nrb".

Deviating without changing all other instances would just introduce inconsistency and probably be confusing. Just a shame they aren't all 3-letters. :) So then the main question remaining is how to distinguish the different forms, particularly brep vs brep+csg but also as it'll apply to the other formats? Space separated using the names above would be: EVALUATE="bot nmg brep+csg" Cheers! Sean p.s.
