Model-Based Definition

This course covers the dimensioning and tolerancing of a 3D CAD model for downstream use. Using a 3D CAD model eliminates the need for a 2D drawing.

Recognize these issues?

What does this dimension actually mean? Team members are interpreting dimensions on drawings differently.

We have difficulty reading 2D drawings correctly and unambiguously across the organization.

How we can help

We visualize the structures of dimensioning a 3D model. This approach has numerous benefits for a variety of business processes.

Course objectives

The goal of the course is to become familiar with the Model-Based Definition (MBD) process. It also covers the annotation mode – the tools for annotating a 3D CAD in PTC Creo, optionally with the Creo GDT-Advisor module.

You will learn to transfer 2D information into a 3D model so that all Product Manufacturing Information (PMI) is present so that the 3D model becomes machine readable. Ultimately, one no longer speaks of a 2D drawing, but a Technical Data Package or a Product Definition Data set.

At the end of the course, participants will be able to:

  • have a better understanding of the MBD process and of how MBD models are created and PMI is required.
  • be able to use a 3D CAD model as a tool to communicate better and more unambiguously across the organization.

This training can be expanded with topics from the GD&T course.
