It's a real nice post rendering touch-up tool. My understanding is that Studio Viz and MicroStation already output to this format and FormZ currently does not. I would like to hear from anyone who has used Piranesi. Still interested I've posted a thread about Piranesi, making the exact same request as Maurice, and the answer for the Webmaster was somehow wishi-washi, so I guest that the more people ask about it, the more reasons they'll have to oblige us. I recommend anyone joining this thread let the powers that be know how many seats are behind thier request too.
Every seat counts.
As developers of Piranesi I hope we're not offending anyone by offering a reply. This information is generated as a by product by 3D renderers, but usually discarded. We also a supply a free renderer called Vedute that will import a DXF or 3DS file, and allow you to setup a view amd render it to Epix format. Converting through DXF or 3DS may blemish the model 3.
