State the frames, units, axes, and transforms a recipient needs to interpret position, orientation, and scale in a CAD or BIM handoff.
Turn a vague “send the model” request into a bounded source-to-destination handoff with a stated purpose, preservation requirements, and evidence needs.
A decision framework for defining the purpose, information layers, evidence, tolerances, and failure disposition that make a CAD transfer acceptable.
Use a repeatable route dossier to separate format capability, product support, preservation evidence, and task-specific acceptance.
Learn what compatibility evidence does—and does not—establish before relying on a CAD-data transfer for real work.
