ASME Y14.41 Standard on Digital Product Definition Data Practices is the dimensioning standard for applying dimensions and tolerances to 3D models. It is based on ASME Y14.5 but is updated to accommodate the rise of 3D CAD models and the inevitable progress to paperless CAD-based 3D design and manufacturing. It points the exact direction that Fusion 360 should be heading. In fact, I'm shocked Fusion does not already follow this standard.
