Re: I CANNOT GET THE DOME EXPANSION Hello, You need to arrange the dome supports according to the solution conditions independent of the structure and perform dome analysis. (In this version, modeling is not done according to the solution conditions with the structure.) Then, you can enter the reinforcement diameter and spacing to meet the required reinforcement area in the Reinforced Concrete Design/Dome dialog and get a drawing. Notes: If the project is not an existing structure, check the defined concrete characteristic compressive strength, bending reinforcement and yield strength values of stirrup reinforcement. Fix errors in geometry control. Good work
