TruTops Unfold 5.3

TruTops Unfold is a specialized sheet-metal engineering tool designed to convert 3D sheet-metal parts into precise flat patterns. It calculates bend allowances and deductions based on material, thickness, bending radius, and tooling parameters, helping you produce production-ready blanks that minimize rework and scrap.

Key capabilities:

• Accurate unfolding of complex geometries, including flanges, hems, and reliefs
• Material- and thickness-aware compensation using configurable bend tables or K-factors
• Automatic generation of corner reliefs and clean transitions to improve manufacturability
• Import of common CAD formats and export of flat blanks (e.g., DXF) for nesting and CAM
• Consistent, repeatable results that streamline quoting, programming, and fabrication

Built for design and manufacturing teams in sheet-metal fabrication, TruTops Unfold shortens the path from 3D model to shop-floor-ready flat patterns while improving accuracy and process reliability.
