Problem optimizing structure

hello all,
I am working on the first stage of a parametric model. the goal is to roughly estimate material use for an efficient framing structure (Concrete, Steel and wood). my model, however, do not show any deflection and I think there is something wrong that I can not figure out.
How can I fix my simple model?

Hi @mst.torabi, you have not assigned the cross sections properly and you have not run any analysis.
Please see the attached definition.

Also please refer to our examples on our website on how to set up a model.
