Generate accurate flat patterns and manufacturing exports for sheet metal components in BricsCAD Mechanical.

This lesson explains the complete unfolding workflow using SMUNFOLD, showing how sheet metal parts are flattened into production-ready representations for fabrication and CAM systems.

You will learn how form features and lofted bends are handled during unfolding, how different unfolding modes affect the resulting geometry, and how bend calculations use K-Factor values and bend tables to account for material deformation.

The lesson also covers exporting unfolded parts with SMEXPORT2D and SMEXPORTOSM, generating DXF files for manufacturing, and using SMASSEMBLYEXPORT to process entire assemblies.

In addition, you will explore layer and color management for unfolded geometry, helping you create clean, organized outputs for CNC cutting, bending, and downstream manufacturing workflows.
