STAAD Pro Model

Hello,

My team and I have been working on a concrete frame for an undergraduate senior design project. We are relatively new to the software, and have modeled everything in the analytical modeler section. In order to design i believe the structure needs consist of "physical" members which are only obtained in the physical model space. Is there any way to convert my current model from analytical modeler to physical modeler?

Hopefully my inquiry makes sense.

Thank you
