How does SPI SheetMetalWorks manage the unfolding of transitions?
When calculating the unfolding of transitions like “rectangle-circle”, “cone”, “y-transition”, SPI SheetMetalWorks interprets the model as a bended sheet metal part. The number of bendings is defined by the designer. The calculated unfolding of a cone is based on the real manufactured part . The 3D Model and the drawing remain clearly, because facets are not represented. You can visualize the borders of the bending zones beneath the bending lines. Free form surfaces as well as conical or cylindrical surfaces with large radii can be treated with a sequence of ready-to-manufacture bending lines for successive bending. The amount of facets for a freeform surface depends on the settings of the parameters or of the possibly attached facet attribute. At the middle of each facet line (bend line) the inclusive angle is displayed. To simplify the identification of bending lines on the blank you can let calculate bending marks. Thus the worker at the bending machine has a better orientation and
