A flat pattern is a 3D sheet metal model in a flattened state.

Create Flat Pattern calculates the material and layout required to flatten a 3D sheet metal model.

The part browser displays a Flat Pattern node, and the flattened state of the model displays when this node is active. After you create a flat pattern, you can switch between the folded part state and the flat pattern state.

When you edit the 3D model, the flat pattern updates automatically. If a model revision results in an invalid flat pattern, a dialog box indicates any error conditions that exist in the flat pattern. You can accept and continue working, although the error warnings persist until the error conditions are eliminated.

You cannot flatten features that require material deformation, such as louvers or dimples. If you place these features onto sheet metal faces using the Punch Tool command, they are represented as 3D features on the flat pattern. They can also be represented using a selected sketch or with a center mark. Sketched and placed features can have unpredictable results, so use Punch Tool to add these shapes to your sheet metal part.

If you cannot unfold a model, (for example, flange features that overlap in the flat pattern), a warning dialog box indicates intersecting features. You can Edit or Cancel the dialog box, or you can Accept the intersecting errors. If you accept, the flat pattern is developed with intersecting features. Subsequent feature creation in the folded model displays the dialog box until you edit the features that intersect in the flattened state.

Export of flat patterns

You can export a flat pattern to an SAT file, or an AutoCAD DWG or DXF file. Full layer support (color, line type, and line weight) is provided for flat patterns saved in DWG or DXF formats.
