DDS-CAD Viewer
The DDS-CAD Viewer allows you to open IFC files(as well as DDS-CAD file, DWG and DXF) to view the model in 2D or 3D on screen. You can also navigate through the IFC model by
object, space and system, and view the detailed parameters of any object, including its associated property sets. It is also possible to switch off the display of objects or change
their transparency, to allow you to view the details of the model more clearly.
