Model-based definition (MBD) allows geometric dimensioning and tolerancing (GD&T), materials, structures, BOMs, product manufacturing information (PMI), configurations, etc. to be specified in the 3D CAD model (3D master) and made available using so-called technical or digital data packages. Model-based engineering comprises not only MBD but also system modeling (see MBSE) and simulation (including CAE) in order to improve efficiency and quality in the development process and reduce the costs and time involved. Therefore the objective is to achieve integrated, end-to-end model-based development and avoid a document-based approach and file-based data exchange.
What we offer you
Does this sound familiar?
- The amount of time and effort involved in creating and managing 2D drawings is getting out of hand due to the fact that you have to map increasing numbers of product, production, language and customer variants.
- Downstream processes like the derivation of calculation and simulation models and the creation of test and assembly plans in the context of quality assurance and work preparation, for example, involve significant manual effort.
- You are aware of the benefits of MBD and MBE but you are still unsure as to whether you can comply with legal requirements and meet the requirements of your cooperation partners and how you can best introduce MBD or MBE.
What if …
… the necessary information was available to everyone involved in a process in digital and machine-readable form?
… you could eliminate a wide range of drawing types and variants by providing role and language-specific views of the 3D master?
… 3D masters could also be used for release, archiving and data exchange and thus replace 2D technical drawings entirely?
- Analysis of existing drawing content (current status) and identification of the data consumers, their downstream processes and their information requirements (target status).
- Specification of the 3D data format on the basis of the identified geometric, geometric-related and non-geometric information. Open and standardized 3D formats such as JT, for example, are preferred in this context.
- Development of processes and methods for establishing and validating MBD/MBE.
- Selection of a converter that supports the 3D process format and the additional information required in the downstream processes.
- Selection of a viewer that supports the functions used in the downstream processes.
- Introduction of MBD and MBE based on the 3D master and TDP/DDP, including training and support.
