Abstract: An industrial CAD system is supplemented with features that allow a developer to easily convert a mechanical CAD model of an automation system to a dynamic digital twin capable of simulation within a simulation platform. The features allow the user to label selected elements of a mechanical CAD drawing with “aspects” within the CAD environment. These aspect markups label the selected mechanical elements as being specific types of industrial assets or control elements. Based on these markups, the CAD platform associates mechatronic metadata with the selected elements based on the type of aspect with which each element is labeled. This mechatronic metadata defines the behavior (e.g., movements, speeds, forces, etc.) of the selected element within the context of a virtual simulation, transforming the mechanical CAD model into a dynamic digital twin that can be exported to a simulation and testing platform.
