We do have some code for booleans/CSG in Poser using the same plug-in technology that we used for Drops and the commercial product, but we haven't integrated it at this stage as we were focused on squeezing as much out of the Drops technology as we could. Nevertheless, our plans are to add it in future products, likely within a few months for Poser and DS when the SDK becomes available. In the meantime the (very soon to be released) commercial product will allow some "boolean-like" functionality. Bill
