Sharing information digitally between stakeholders is at the heart of a model-based definition, but the data out is only as good as the information that is captured. This presentation will explore differences of connecting Product and Manufacturing Information (PMI) to a variety of references in a model-based process in order to produce quality output with minimal or no consequences.

We know that connecting PMI to all relevant references is important, but does it matter how those references were defined? How do these references differ when looking through the lens of a Coordinate Measuring Machine (CMM) or a Computer Numerically Controlled (CNC) program? What changes if you are connecting PMI to a hole feature in a native CAD model vs. the surface of a cylindrical feature in a neutral format? But wait! Some CAD systems split cylindrical features into two surfaces. What does that do to the definition?

We will demonstrate that it isn’t hard to connect PMI to geometry, but what are the consequences if you don’t fully understand how the output will be used? This presentation will discuss common PMI data exchange scenarios, the potential for change in the way the data is communicated and how to identify such associated risk.
