Hello,

I am having a funny problem.

Let me give two examples:

1) I draw a roof and export it as an OBJ file. I bring it in and place it on the house. In the 3D view the roof looks great but I see a gray block at the end. It is the size of the end view of the roof. I can not see through this block.

2) I draw a triangle window. Again, I export it as an OBJ file. I import it ( as furniture ) and place it into a wall. Although I see the window as a triangle, the "hole" for the block is a square. I see a chunk of wall missing.

I assume (maybe wrongly) that this is one in the same problem?

The window is annoying but not really a problem. The gray block at the end of the roof is a real problem. I can not get a good picture of the house with a large gray block at the end of each roof.

Thanks ..... Mike
