Traditionally, piping systems have been defined in Modelica, by connecting components in a model diagram. Additionally, the system engineer must enter values for parameters such as pipes diameter and length, volume of vessels, etc. Those values are often also defined in CAD piping 3D designs, for example in CATIA from Dassault Systèmes. More convenient definition of the piping system can be made, directly using the data from the CAD environment. A tool has been developed, to extract data from CATIA piping 3D designs. This information is used to generate corresponding Modelica representation. Methodology based on the use of Modelica extends (inheritance) is applied to add controllers and other features to the generated model for dynamic simulation. Simulation results can be visualized directly in the 3D view of the piping design. Specialized tools are developed, based on generated Modelica model, in order to enable quick calculations from the piping 3D design directly in the CAD environment.
