Microsoft Visio is easy and intuitive to use thanks to the Microsoft Office interface. Visio is widely used in many companies and is part of the standard. Our PlantEngineer software relies on Visio as a graphical platform, as Visio is particularly suitable for drawing schematic representations such as P&IDs. Visio and PlantEngineer can be learned quickly without prior knowledge. We extend Microsoft Visio with a complete development environment for designing intelligent and standard-compliant P&IDs according to ISO10628 and automated documentation. Standardized, open interfaces allow integration of any data source. With PlantEngineer you get out of the box capabilities that go far beyond a simple drawing tool. Close cooperation with the Microsoft Visio development team helps us to develop new innovative features for our customers.
