Piranesi Plugin for Sketchup
Sketchup modelers can export straightforwardly to EPix files. To set up the plugin, download the zip archive file and copy epix.rb to your SketchUp plugins folder. After restarting SketchUp, there will be a new menu item File > Write Piranesi Epix. The users should have installed Piranesi previously.
Piranesi plugin is compatible with SketchUp 6, 7 and 8. For sketchup 8 , Piranesi 6 Pro is necessary. The users can export SketchUp Pro direct to EPix files.

If EPix export is not supported then the users can avail the free Vedute program which can transfer from DXF®, 3DS, SKP, FBX® and MicroGDS® MAN files to an EPix file. Vedute is incorporated with Piranesi.
