This partial list of new sheet metal functions in BricsCAD V17 is provided by Bricsys. The new commands are in alphabetical order, followed by improved functions. For the full list, look at https://www.bricsys.com/common/releasenotes.jsp?i=4471
BricsCAD V17 adds parametric form features to the sheet metal module. “Form features” mimic the process when a forming tool deforms a piece of sheet metal. After the form is applied (using the new Form Features tab of the Tool Palettes panel), you can edit it directly and parametrically through the Properties bar.
The library contains most commonly used form features, such as bridge, louver, and emboss. You can import form features from other systems, and define your own custom forms. When you import geometry from other CAD systems, you can search for similar form features, and then replaced them with ones from your libraries.
The smFlangeBend command lets you bend an existing flange along a line, obeying the k-factor for given bend radius. The “k-factor” determines how much of the material’s thickness compresses and how much stretches during the bending process. When you import geometry, BricsCAD recognizes incorrectly-made bends and automatically repairs them.
IMPROVED: LOFTED BENDS
Lofted bends gain a feature validation function, which lets you ensure that the bend will work correctly.
