Walls with different shape surfaces

[moshira_hassan]

Hi

I've created an eight-sides polygon room .... I want to make the wall interior surface to be smooth circle while the exterior surface to be as polygon as it is ... is it possible???

Yes and No and maybe Yes.
It is possible to do it, it's just a matter of how you want to look at it.
If you are to look at it from a sketch design concept, you could do it as an in-place family, by creating a wall, using the extrusion tool. I've attached an image.
The other approach would be to look at it from a constructability point of view. What you are looking at is an External skin (Wall) and an internal skin (Wall). Using this method ensure you join geometry between the two wall leafs in order to allow opening to penetrate both walls.

thanks a lot ... both ways works for me but i think the second one about having two joined walls are better to be able to add different materials for each side of the wall ..
