While there are several thumb rules and guidelines for dimensioning the drawings for sheet metal fabrication, we have enlisted a few important and frequently used aspects. Drawings should not have broken geometry when depicting sheet metal parts; Show grain direction in parts made of stainless steel Drawings will need to be converted to a flat pattern for fabrication, however, and 2D drawings are far more useable in sheet metal manufacturing. Where 3D drawings are used, they should be made with a sheet metal module, and good design practices should be followed so that the 3D dimensions match the 2D design.

First, check out ordinate dimensioning, it can really clean up sheet metal drawings where you need to show hole locations but don't have space for dozens of stacked dimension lines. With ordinate dimensions, I would be surprised if you need more than two front views for a single part. It still might be crowded though!

When cuts are made into the flat pattern of a rolled sheet metal cylinder (or semi-cylinder), it is not always easy to extract model dimension data in a SOLIDWORKS drawing. Without proper design intent, detailing the flat pattern positions may not work. To draw sheet metal bend lines, first determine the sheet metal bend allowance. The bend line position is determined based on the bend allowance.In the illustration below, the bend allowance is calculated using the formula: inner dimension + inner dimension + compensation factor.. Related reading: Bend Allowance Formula The sheet metal thickness is .
