Simple flat pattern generator for truncated cones

grabcad

For years, I've employed a method to create truncated cone patterns by utilizing sheet metal cutting. Although most 3D modeling software offers lofting, this approach can be performed using only calculator-based 2D CAD, which is faster. Additionally, the resulting patterns consist of arcs instead of short line segments, unlike some lofts. This method is particularly beneficial when working with plasma cutting machines that handle thin sheets rapidly, as it avoids the challenges posed by frequent starts and stops in shorter line segments. To adapt this technique, simply modify the function and variable table to suit your specific needs.
