I'm trying to find a way to model a curved roof which would consist of several bended I-section beams. I would try Object Bending option however I cannot see such an option in the Edit menu (please see the attachment) eventhough the Solid Modeler is enabled.
I guess I can use the option Extrude Along Polyline however I don't prefer to bother with solids when there is a chance to use I-sections and analyse in Steel Design. I also have doubts when creating the curved beam by drawing an arc with "create bars" option because the bars would be too short that would cause the bending strength of the whole beam would be overestimated.
Can someone please tell me why the Solid Modeller options below Face offsetting as in the following link are missing for my version (I'm using RSA2013)? Also any ideas about how to model a curved roof under these circumstances are welcome.
P.S.: I tried both with Volumetric Structure Design and Shell Design Modules, no results.
