According to wikipedia, PMI is defined as:
Product and manufacturing information, also abbreviated PMI, conveys non-geometric attributes in 3D computer-aided design (CAD) and Collaborative Product Development systems necessary for manufacturing product components or subsystems. PMI may include geometric dimensions and tolerances, 3D annotation (text) and dimensions, surface finish, and material specifications. CAD application literature may also refer to PMI synonymously with Geometric Dimensions and Tolerances (GD&T) or Functional Tolerancing and Annotation (FT&A).
To anyone that has been in manufacturing, it sounds like a great way to hand off data from engineering to manufacturing.So why aren’t more companies taking advantage of PMI?
