I’m going through the entities for MEP looking for a specific parameter of which I do not know the name of (yet), and I’m hoping someone here can help me out.
When coordinating MEP I often find myself overwhelmed by the sheer amount of installations in our projects. To make sense of it all, we assign specific colours to a parameter which Revit calls ‘System Abbreviation’ for Mechanical and Plumbing, or Function Code for Electrical. Every system has its own code and their own colour. These, however, are Revit-specific System classification parameters.
Within Solibri Office we call upon these parameters and dedicate a classification to it, which we use to change the system’s modelcolours like this:
I’ve been going through the BuildingSmart documentation (IFC4.2) but I just can’t find a property in IFC that would store such information. Perhaps someone can point me in the right direction?
Systems in IFC are stored in IfcSystem entities. The code for the system should be stored in the Name attribute of each IfcSystem entity.
IFC does not store a colour to “categorise” things. These arbitrary colour schemes, based on a property, are a function of the IFC viewer. Solibri has this feature, as do others, such as Autodesk Assemble, and the free software BlenderBIM Add-on.
That said, if you wanted to, you could store the colour as a regular colour property of the object, see @ReD_CoDE’s link.
