Drawing Checklist

The document provides a checklist for ensuring drawings contain all necessary details. It lists over 30 items to include in drawings such as different views, dimensions, tolerances, notes, and ensuring all needed information is provided for part fabrication. The checklist aims to make drawings clear, unambiguous representations that specify everything required to make or assemble the designed part.

Drawing Checklist

Use this to ensure completeness of your drawings. Remember that your drawing should be easy to understand
and specify everything one needs to make or assemble the design. If you think something may be ambiguous,
add additional details and/or notes for clarity.

 Views are arranged in the correct (first/third-angle) orientation


 Hidden lines are shown except where they obscure the view
 Tangent lines are omitted unless needed for clarity
 All features of the part are shown in true size in at least one view
 Location and size given for all features
 Features are fully-defined but not over-defined
 Critical dimensions are toleranced
 Non-critical features provided with looser tolerances
 Dimension and tolerance precisions match
 Precision of non-toleranced (i.e. using title block tolerance) dimensions are chosen appropriately
 A tolerance stack has been performed to ensure that all tolerances selected are appropriate
 Dimensioning to hidden lines is avoided
 Center lines/marks added for revolved and symmetrical features
 No dimension lines are crossing
 Dimensions are placed outside the view
 Quantity (i.e. 6X) noted for patterns of features
 Use of TYP is unambiguous
 Reference dimensions provided where needed or requested (i.e. overall dimensions)
 Diameter symbols added to cylindrical bosses, holes, and arcs greater than 180 degrees
 Radius symbol added to fillets, rounds, and arcs less than 180 degrees
 Material (alloy, heat treat, and specification) noted on drawing or referenced in BOM
 Coatings noted on drawing or referenced in BOM
 Location for coating masking (if any) noted
 Critical finishes noted
 Notes indicating non-obvious critical/sealing surfaces that must be free of scratches
 Basic edge break requirements are conveyed with a note instead of dimensions on the face of the drawing.
 Marking instructions and location provided if required
 Geometric dimensioning and tolerancing applied where needed
 Basic dimensions are used where needed

 Have I given the machinist everything they need to make this part?
 Is this drawing clear?
