Building model – Structure

You are here: Modeling and design > Create a building model > Structure

The building model is a virtual, three-dimensional, graphically constructed structure. It is the basis for three-dimensional representation and for most integrated calculations. The information levels of the building model correspond to the structure of a real building:

Building

Uppermost structural unit of the building model and the project. A DDS-CAD project can contain exactly one building up to 100 storeys. The dialog Building manages building related settings and components under several tabs.

 

Storey

All building elements of which the floor is on the same level belong to a storey. Each storey corresponds to a model in the DDS-CAD project. Please consider the note regarding structural design of a project. The dialog Storey manages storey related settings and system components under several tabs.

 

 

Area

External setting for several rooms with common characteristics within the same storey. Areas are needed for:

  • the construction of the roof
  • The recognition of DWG/DXF objects
  • The separation of building sections with different floor/ceiling heights

The settings of n area are managed in the dialog Room.

Room

The most important structural unit in the building model with great influence on the project work. The ceiling height controls the mounting height of objects to the ceiling (lights, air terminals), the room type defines important parameters for heating and ventilation systems. The dialog Room manages room settings and system components under several tabs.

Building component

Collective term for the encapsulating surfaces of a room (walls, floors, ceilings) and therein included openings (doors, windows). The properties of the component affect mainly the result of the heat load.

 

Type

Structural unit for additional structures of the building.

You can include multiple rooms independent from their storey or area into a zone. Typical applications are:

  • Usage units for the controlled ventilation systems in apartment buildings
  • Usage units for the potable water calculation (calculation of the peak flow rates)
  • Sorting the parts list (by zone)
