What does PMI stand for in drafting?

PMI stands for Product Manufacturing Information. In the context of drafting and design, PMI refers to the information included in a 3D model that provides critical data for manufacturing processes. This can include dimensions, tolerances, surface finish specifications, and other annotations that are essential for the manufacturing operations to understand how to build the part or assembly accurately.

Including PMI directly in 3D models is a part of a broader initiative to improve communication and reduce errors in manufacturing. Instead of relying solely on 2D drawings, which can often be misinterpreted, PMI allows designers and engineers to embed this essential information within the model itself, facilitating better collaboration across teams and a more efficient workflow.

Therefore, recognizing PMI as Product Manufacturing Information is crucial in understanding modern drafting practices and ensuring that all necessary manufacturing details are conveyed clearly and effectively within the design files.
