There are several methods to model shear wall/slab/mat in staad CE, broadly by physical modeller and analytical modeller, as far as the analytical method is considered, slab/mat/shear wall can be modelled through various techniques, like plate element/parametric model/surface cursor etc. Each methods have some advantages and limitations, for example, if we model a lift core wall through parametric modelling option, the salient feature of parametric modelling option is better connectivity to the other slab/beam/adjacent structural members but the limitation is that RCDC doesn't support the "lift core wall with openings", RCDC only support the lift core wall without opening in it, so we demand that we haven't any need to have various options for plate modelling with limitations, we need to have one options that has no major limitation like RCDC doesn't support the shear wall with openings etc..
Thank you for posting this idea. It seems that the request is for the RCDC application to support definitions of shear walls with openings. I have thus changed the title and moved this to the portal for the RCDC project team.
