Many thanks to all .. the answers you have provided are the answers I had been wanting to hear. Two software companies that I have dealt with in the past 4 or so years have all but driven me mad; so hearing how responsive Eovia is, well it makes my purchasing decision much easier. The workflow and UI feel very good to me and makes sense to my feeble mind. When Eovia updates their 'promotion' page and I see what the next offer is, I will be buying CS4 Pro. Hexagon was mentioned as a modeler, will this replace the modeler in CS4P? thanks to all, Louis
