The building model is a core element of the DDS-CAD philosophy and the basis for most integrated calculations. This chapter describes the internal structures and strategies for the development, processing and use of the building model.
Like a real building, also the DDS-CAD building model exists of multiple structural units. This chapter describes the content, meaning and classification of the overall concept.
The building model is created either by importing a suitable IFC model or by manual construction in DDS‑CAD. This chapter describes two strategies for manual construction. The choice of strategy depends on the format of the floor plan provided
Many situations can force a change to the building model. In this chapter we describe the various functions using different examples.
You can assign multiple rooms to a higher-level structure, regardless of their storey or area affiliation, and thus differentiate them from other rooms.
There are two functions with different emphases in DDS-CAD.
You can merge all storeys of the building in a common model or show individual models of other disciplines and storeys (ghosting). The main applications of the function are varied.
