# Sheet Metal

Sheet Metal components are widely adopted across industries (e.g., computer chassis, electrical enclosures) due to their light weight, high strength, and mass-production suitability. CrownCAD's Sheet Metal Module delivers end-to-end design capabilities covering:

  • Base creation

  • Bending operations

  • Forming features

  1. Creating Base Features:
  • "Base Flange": Sketch profile → Generate parametric sheet metal

  • "Convert to Sheet Metal": Transform existing solids into manufacturable sheet metal parts

  1. Bending Operations, Industry-standard tools with bend parameter control:
  • "Edge Flange": Create flanges along selected edges

  • "Sketched Bend": Define custom bend lines via sketches

  • "Hem": Form folded edge reinforcements

  • "Miter Flange": Generate angled corner connections

  • K-Factor / Bend Allowance

  • Bend deduction tables

  1. Forming Features:
  • "Punch": Create louvres, ribs, extruded holes

  • "Forming Tool": Apply standard dies (e.g., embosses, dimples)

  1. Flat Pattern Management
  • "Unfold": Flatten selected bends (full/partial)

  • "Refold": Restore 3D state from flat pattern

  • Reference plane selection determines unfolding axis
