Exporting shadows in vector format
-
Does anyone know of a method of exporting shadows on a building facade in vector form. I often have to produce elevations in dwg/dxf format so the rendered output with textures in raster format fron SU is of no use to the client. They only want something that they can use in AutoCAD. I have tried to export the elevation in Hidden Line format to a jpg file with shadows turned on. In Photoshop I delete everything except the shadows and bring this file into Adobe Illustrator and then convert this to a vector file. I then export this file as a dxf file and bring this into AutoCAD where I overlay it on my normal 2D dwg file, but I can never get the scale correct. I suppose I could include a scale bar in the initial jpg and use this to rescale the vector file in AutoCAD. I just feel the shadows give the otherwise bland AutoCAD file a bit of depth but can't get them from SU into AutoCAD in a convient way.

This http://sketchucation.com/forums/viewtopic.php?f=323&t=41885 might be what you need, but read the post associated with it carefully.
Also there's Chronolux (which I keep meaning to try out) http://sketchucation.com/forums/viewtopic.php?f=323&t=40569&p=374650&hilit=chronolux#p374650

Thanks, I've looked at Shadow Projector briefly but I don' think it creates a polygon of the shadow area. I need to select this to fill it with an AutoCAD hatch or solid fill with grey. When I export from Adobe Illustrator as a dxf I can easily select this in AutoCAD and hatch it. It's just a rather cumbersome process and I don't have Adobe Illustrator on my home PC.
