How do you put together a ceiling and the corresponding RCP? Lights, hvac diffusers, fire protection, cameras, sprinklers, exit signs, etc. These objects need to show up as custom symbols, that we can change for each type. The ceiling grid also needs to be highly customizable. Like putting a 12’x2” light centered on one of the grid lines, and changing the grid lines at will. Also, ArchiCAD seems to not be able know what an RCP is. I have search throughout the forums and have found no good solutions.
