OpenSCAD feels awesome to start with, but is ultimately a disappointing experience because it lacks parametric solver capacity; data flow is one way, from the script, to shape generation, to CSG operations, and you cannot do quite reasonable things like extracting dimensions from a CSG-constructed shape and feeding them back into the script. A better system would enable true constraint-based parametric design, but I think doing so would involve an order of magnitude more complexity in the implementation, and quite probably infeasable compute times.
