thanks for your help, after much messing around, i finally got the shape i required by drawing completely new using nurbs. However, ive done one duct, but i need a further 3.... I tried repeating the process, but just when i get the path perfect in one view, when i switch to the other to edit it there, the whole thing gets distorted. Im having majorly trouble trying to control the nurbs shape, even when using the different constraints

I tried once again, with the path object not having any sharp turns, and the radius of circle being small, but still it tells me theres an invalid path or profile object. i cant add two objects, cause it wont let me create even part of the shape, and as it needs to twist in 3dimensions, it would be difficult to line it up. Whats the hvac tool?

i tried adjusting the path, but it keeps saying its invalid when i click exit group. I also tried creating the surface with nurbs, but once again, once i edit the path using the 3d edit tool, it says the path is invalid

I have to create a cylindrical duct, to form over the shape of a building. I used the extrude along path tool, which gave me the perfect shape in elevation, however in plan it is completely linear- I need to also have it weaving left and right in plan and elevation. Is there a way to create a double extrude path, or create it in elevation, then manipulate the shape in plan?
