Drawing-based processes are established in the areas mentioned. We will show you how to use your 3D models and work model-based so that your data flows seamlessly through your company and can be exchanged uniformly with suppliers. This will help to avoid errors in the future and make collaboration more efficient.
NX® MBD
Have you ever thought about making your development, design, manufacturing and quality control paperless?
The basics to get you started.
PMI - Product Manufacturing Information
Non-geometric data describing the 3D model so that this CAD design information gets into CAM manufacturing. PMI alone does not enable faster manufacturing.
MBD - Model Based Definition
A complete digital description of a product in a 3D CAD model. The MBD concept is to be considered program-unspecific for the time being. As a source of truth, the 3D model replaces the drawing.
MBE - Model Based Enterprise
The process of reusing the model-based definition by downstream departments throughout the company and thus successively redesigning processes to become paperless.
TDP - Technical Data Package
A collection of multiple files to describe a product or product component. The technical data package can contain 3D data with PMI, 2D drawings, parts lists and other documents.
In summary, it can be said that PMI replaces the classic drawing. With MBD, based on PMI, the 3D model becomes fully digital, more automated and can be used by both design and manufacturing. The combination of PMI, MBD and a TDP concept can lead to a fully comprehensive MBE concept early and support the way to enterprise-wide automation and paperlessness.
Challenges.
- Shorter design times
- Drawings difficult to interpret
- Disruptions have a major impact
- Errors increase costs
- Lack of 2D/3D associativity leads to quality problems
Avoid media breaks with MBD.
Today's process.
NX® CAM & Calypso | PC DMIS pull a copy of the 3D model and drawing from NX® CAD in order to then adapt it for their own needs. No common basis, but always a copy for the respective departments.

Future Process.
All departments work with a 3D model, which provides all relevant data digitally. The 3D model replaces the drawing as the source of truth. Drawings are now only created in exceptional cases.
