Thank you Okh. Your instructions were great and it worked. The only problem I have now is that while I see the 3d model in Sweet Home 3d, in the view plan I don't see it set right, just a point. I am working on it.

I have created a 3D model for a piece I need in the Art of Illusions. The Sweet Home 3D document mentions that one could import the models made in the Art of Illusions. But I don't know how to do it and I wonder if I get get help with instructions on how to import a model made in the Art of ...

I just realized I put semicircular where as I meant quart of a circle. How could I access quarter round walls and quarter round staircase? I see that one can do half circle wall in Sweet Home 3D.

thanks for help.
