Please see screen shot. Can you see the shadows are not complete on some of the faces? There are no duplicate faces. I used ThomThom’s Cleanup3 and it fixed a bunch of things, but it still is behaving funny. The shadows acutally behave the worst in this Hidden Line style, whereas in other styles such as Shaded, there are no problems.
The model came from an imported dwg and I wouldn’t bother asking this if it weren’t for the fact that when I export the shadows as an image file it shows up quite pronounced.
Can anybody help?
