A unique feature of DDS-CAD is its ability to generate automatic system diagrams based on model data. Until version 15, DDS-CAD supported the generation of system diagrams for power supply, emergency lighting, data and fire detection systems. Thanks to the popularity of this feature, we have extended the number of available diagram types. With DDS-CAD 15 it is now possible to also generate automatic system diagrams for both security systems as well as nurse call systems. These two new diagram types ensure that productivity boosts are also gained within these two specific fields of expertise.
