Predominantly used in NPR or 'non-photorealistic' rendering, Piranesi also works well adding effects and interest to photorealistic images as here, in a beautifully detailed image by Jacek Mielewski, an architect at MAAG in Warsaw, Poland.

Follow these steps to create a Piranesi EPix file from a model created in Autodesk® Revit Architecture® 2009 or 2010.

Piranesi 5.1, Piranesi 2010 Lite, or Piranesi 2010 Pro is required to use FBX files as described below. For earlier versions, Revit users should export to DXF and then use Vedute to import the DXF file, define a viewpoint, and export an EPix file.

We are aware of problems with materials when using FBX files from Revit 2011. We are working with Autodesk to fix this issue. In the meantime, we have a test version of Vedute which handles Revit 2011 materials better. Please contact us for details.

To export your Revit model to an image file:
  1. Start Revit and open your model.
  2. From the Project Browser, select the 3D view you wish to use.
  3. On the Design bar, click Rendering and then select Rendering Dialog.
  4. On the Rendering dialog box, click Render.
    Make a note of the pixel Width and Height values as you will use them later.
    If you want a better resolution than 'Screen', select the 'Printer' option under Output Settings and select the required DPI from the list.
  5. When the rendering has finished, click Export.
  6. On the Save Image dialog box, select png from the file type list, specify a name for the file and click Save.
  7. Close the Rendering dialog box.
  8. From the Revit File menu, select Export and then select 3ds Max (FBX).
  9. On the Export 3ds Max (FBX) dialog box, specify a name for the file and click Save.

To create the EPix file:

  1. Start Vedute and select Open Model from the File menu.
  2. In the Open Model dialog box, select the FBX file that you previously saved and click Open.
  3. From the Window menu, select Named Views.
  4. From the list of views, select the saved view and click Apply.
  5. If you wish to add a ground plane, on the Edit menu, click Add Ground Plane and specify the size and height for the ground plane in the dialog box and click OK.
  6. From the Edit menu, select Image Size and change the pixel sizes to match the sizes you noted earlier if necessary:

To overlay the image file on the EPix file:

  1. Start Piranesi and select Open from the File menu.
  2. In the Open dialog box, select the EPix file that you previously saved and click Open.
  3. From the File menu, select Import.
  4. On the Import dialog box, select the png file that you previously saved and click Open.
  5. On the File menu, click Re-Render to write the current RGB channel to the Restore RGB channel.
  6. Save the EPix file.
