I go to window from the top menu, then shadow settings in the drop down menu, it opens a menu file, there is a checkbox for display shadows, we uncheck that box as instructed, under it is time and date sliders, under that is light and dark sliders, then we have written, display, under that check boxes for on faces, on ground , from edges. And nothing else, this is version 5 of sketchup, either Im on the wrong thing, or in my version the setting is some other place, or it is in version 6 only. mine is this [image: Shadow-settings.jpg] not this [image: dczk5s33_38f666cdcj.jpg] EDIT I found it, its in Display settings for versions of SU older than 6

.3ds file export has the option to weld vertices, but this will lose pretty much all smoothing groups and material placement. Or you can choose to keep material placement, but thill will make SU not weld any vertices. So its often not helpful. I think some people use .obj export maybe? Chris
