3D-CAD

Intelligent digital twins (IDT), as the next evolutionary stage of digital twins, have the potential to accelerate and optimize processes within companies. The intelligent twin presented here independently analyzes 3D CAD data and automatically conducts a physical simulation of the assembly. Utilizing the IDT optimized assembly, reduces production costs and accelerates the production planning process. This specific use case illustrates the broader possibilities and advantages of IDTs, offering valuable insights for their transferability.

Today’s new products and services must be marketed in cycles which are rapidly becoming shorter and shorter. The pricing pressure and the progressing trend toward individualisation of products pose a tremendous challenge for major sectors of the industry. In the future, therefore, the implementation of digital methods will be necessary to a much greater extent than in the past, not only in product development, but also in process, production, and factory planning. For ensuring their own survival in a globalised world, small and medium-sized enterprises will also be faced with the inescapable necessity of introducing the digital factory. In this context, 3D-CAD factory planning can be regarded as a basic prerequisite for successful implementation of the digital factory. However, this prerequisite has not yet been satisfied in many companies. In the present publication, an overall method for implementing computer-aided 3D-CAD factory planning in conformance with the requirements is ...

For an innovative and efficient product development process the use of modern parametric 3D-CAD systems is of increa-sing importance. Basically in the internal digital data structure of a 3D-CAD model geometrical and topological data as well as the modelling history is being stored. Additionally, the feature technology enables the models to be developed with the help of defined zones of geometry with embedded se-mantics. By means of the integration of geometrical and non-geometrical information into the 3D-CAD models it is possible to embed product specific knowledge and design know-how into the models. The department of Computer Integrated Design (DIK) is investigating methods and tools for developing, managing and reusing knowledge-based 3D-CAD-models.
