Draping of imagery on a terrain model is now available in ProStructures. Bentley Descartes is no longer required to attach the Procedural Material "DCDRAPE.PAL," and any raster required for the draping. To allow images to drape under ProStructures, turn ON the "Draping" option from the Draping column of the Raster Manager dialog. Once turned ON, rasters will drape in ProStructures. A raster can also be displayed as "undraped." This is possible by turning OFF the Draping column option of the Raster Manager dialog.
