Use your newly created drape attribute with default offset for colour zone types. eg Black or near black offset -1 foot. Earth tones incl blue 0 feet offset. Grey +1 foot. White + 35 foot. Perhaps + level textures would have to be converted to objects or pseudo objects to somehow generate vertical fill. By psudo object I mean a texture that behaves like an object with a predefined height. An oxymoron I suppose (textures with object like behaviour, but efficient). Perhaps that is the challege. /Gavin newby
