TolerancesAdd tolerances to the dimensions based on ISO standardsCheck material specification sheet as per notes for tolerancingDon't give basic dimensioning unless necessaryUse ISO system of Limits and Fits for hole diameterGive appropriate tolerances for cut profilesTolerance for radial dimension should be 3.0Tolerance for length dimensions of bend pipes/tubes must be 3.0DimensioningChange radius dimensioning styleMaintain 10mm gap between all dimensionsKeep angles as referenceKeep 2X, 3X, etc in weld tailLeave 1.5mm gap from dimension lineKeep centreline extension within 3mmFor symmetric parts and holes show centerlineRemove extension lines from intersectionsOtherOrient views horizontally as per base planeIntegerize weight above 5kgShow boundaries for Section ViewsUse symbols as per THCM Drawing Guidelines
