Hey I am also getting the same problem as a new beginner I didn't understood the offset removing answer (communities.bentley.com/.../staad-rcdc---beam-bm-detailing-failure)
how do I remove offset I have already created mesh and now every beam got divided into small section of individual beams ... In run and analysis using staadpro it passes with zero error and zero warnings but when I import it to RCDC it fails out almost every beam group what should I do or how do apply above solution?
