A quotation moves fastest when the drawing and the intent behind it arrive together. Alongside 2D and 3D files, tell us the material, the quantity, the surfaces that matter and the target lead time. Where a tolerance is functional, flagging it helps us hold it without over-constraining the process.
If a feature is negotiable, say so. Knowing which dimensions are critical lets us choose the machining strategy and the inspection plan that protect the fit, rather than spending time on tolerances that do not affect performance.
