Model dubble-curvature beam

[georgetoneverland]

Hi! My first post here.

I want to model some beams like ones attached below, so curved in plan but also in elevation. 

Is it possible to model and rebar it in a clean way? 

Thanks!

You can do it in several ways , but I think the more appropriate one is to create a Sweep:

• first create a curved Wall that has the desired curvature in Horizontal Projection of the Beam
• then create a Roof by Extrusion that has the curvature of the Beam in Vertical Projection
• Attach the Wall ( Top) to the Roof
• Create then, a Component Model in Place>Structural Frame>Sweep . Pick the intersection line (Wall/Roof) to be the Path and choose the appropriate beam section Profile previously loaded.
• The Sweeped Beam will have a double curvature now.

The result:

...and the screencast that shows the steps:

note:in my screencast, as I had no appropriate Profiles loaded , I had to make a custom rectangle profile for the Sweep.
