Product and manufacturing information
Product and manufacturing information, also abbreviated PMI, conveys non-geometric attributes in 3D computer-aided design (
Uses and visualization
[edit]The PMI annotation is created on the 3D
PMI items are often organized within annotation views. Annotation views typically view including camera/view position, selected and also the particular state of the assembly (visibility, rendering mode, sometime even position of each element of the assembly).
For anyone to be able to display any kind of PMI View, Adobe Systems has unified their format and added their description to the PDF format (version 1.7).
Communication deliverables
[edit]In an effort to unify the visualization of PMI across the different existing solutions, Adobe Systems has released a version of the Myriad
The ISO 10303 STEP standards also handle a wide range of PMI information. ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information. It is an ASCII-based format.[1]: 59 Its official title is: Automation systems and integration — Product data representation and exchange. It is known informally as "STEP", which stands for "Standard for the Exchange of Product model data". ISO 10303 can represent 3D objects in Computer-aided design (
Standards
[edit]Industry standards for defining PMI include ASME Y14.41-XXXX Digital Product Data Definition Practices and ISO 1101:2004 Geometrical Product Specifications (GPS) -- Geometrical tolerancing—Tolerances of form, orientation, location and run-out.[1]
