Answer:
No, this is not possible in RF‑CONCRETE Surfaces (in the current state of development).
If you have activated a basic reinforcement and/or the serviceability limit state design in RF‑CONCRETE Surfaces, there are several options available in the Results navigator for the graphical display of the "provided reinforcement".
However, no rendering of rebars or mesh reinforcement is generated in this case. It is rather a color representation of the result values in [cm²/m] for the longitudinal reinforcement or in [cm²/m²] for the shear reinforcement.
