I *love* PlantStudio! Prior to the current version, I exported solely in DXF, then applied materials in Vue. Now I export in 3DS or OBJ, depending on the model. Still need to apply materials, although the colors transfer. Visit my Digital Greenhouse (at the URL) for some PlantStudio goodies, plus a tutorial for applying materials in Vue to PlantStudio objects. :)
