A practical framework for marking critical dimensions while keeping non-critical features manufacturable.
A practical framework for marking critical dimensions while keeping non-critical features manufacturable.
Only the dimensions that drive fit, alignment, sealing, bearing location, or moving interfaces need tight callouts. Everything else can often follow a general tolerance class.
Surface finish and tolerance are different cost drivers. A visible face may need a finish note while hidden geometry can use a standard machined surface.
Upload a 2D drawing when datums, thread depth, flatness, perpendicularity, or inspection method matter to the final part.
