Sheet Metal tools in the application offer a comprehensive set of features for designing and editing sheet metal parts with precision and control. These tools allow users to create intricate geometries, such as tabs, bends, flanges, and hems, while preserving material integrity and adhering to key sheet metal design parameters like bend radius and k-factor. Whether designing structural components, mechanical enclosures, or decorative parts, the Sheet Metal tools simplify the entire workflow from initial design to flat pattern generation. The Sheet Metal toolset is located in the Tools menu. There are six primary Sheet Metal tools available: Tab, Bend, Contour Flange, Flange, Single Hem and Unbend.
Sheet Metal Part Example
The Tab feature creates a flat, protruding extension from a sheet metal part with precision and control. A tab is typically a planar section that remains in the same plane as the base sheet or flange it extends from. It can take various shapes: rectangular, trapezoidal, or custom profiles depending on the design requirements. Tabs often serve as the foundation for additional sheet metal features, providing a starting point for operations such as bends, flanges, or cuts. This tool is essential for building the initial geometry of a sheet metal component.
Open the Sheet Metal Tools palette from the Tools menu and select the Tab tool.

Unbend
The Unbend tool is used to return a bent or curved section of a sheet metal part to a flat, planar state without changing its design. It reverses the deformation by selectively flattening bends or regions while maintaining material properties and adhering to established sheet metal parameters such as bend allowance.
The K-factor is a value that represents the position of the neutral axis, the line within the sheet metal that remains unstretched and uncompressed during bending, relative to the material thickness. It is a dimensionless number, typically ranging from 0.3 to 0.5 for most materials and bend conditions, though it can vary between 0 and 1 depending on factors like material type, thickness, and bend radius. The K-factor is essential for calculating the bend allowance, which helps determine the accurate flat pattern length before bending. In practice, it ensures precise fabrication by accounting for how the material behaves during the bending process.
Open the Sheet Metal Tools palette from the Tools menu and select the Unbend tool.

One of the most powerful, yet least known tools in professional versions of TurboCAD is the Drafting Palette. The Drafting Palette is used for the creation of 2D construction and manufacturing documents from 3D designs, including ACIS® solids and 3D surfaces. It can be used in conjunction with both 3D Architectural and Mechanical designs. 3D Designs created or imported into TurboCAD’s Model Space are fully associative with the 2D views and construction drawings that the Drafting Palette creates in TurboCAD’s Layouts, even when working on an XRef. Dimensions are also fully associative. For Mechanical designs, both individual parts and assemblies can have any of 10 different standard views, 9 different preconfigured sectional views, as well as custom, detailed views chosen by a line or other closed arc or polyline. Recent versions of TurboCAD have also added the ability to add Layer Sets containing both visible and non-visible layers, and no scaling of Drafting Objects can be controlled by the Local (right click) menu. The Drafting Palette gives you great artistic control over how your views will work. Each drafting object placed on your Layout may be hatched, colored, or have its line weight and style adjusted as needed, with separate controls for visible and hidden line. In addition to standard cross-sectional views, fragmental views can be created and Drafting Breaks added.

The Drafting Palette works with over a dozen file formats and helps make TurboCAD Platinum, Professional and LTE Professional an excellent collaboration tool with other CAD applications. This includes Architectural formats such as .SKP (SketchUp) and .DGN (MicroStation/Intergraph) so the Drafting Palette can be used to create elevations, floorplans, sections, even detailed views, all of which are associative to changes in the model!
