SigmaUNFOLD

Industry-Leading Unfold Technology for Flat Pattern Creation

SigmaUNFOLD recognises sheet metal bend features in a 3D model and flattens them using accurate K-factor calculations. It supports assemblies and part collections, giving you a realistic flat pattern representation to support your sheet metal fabrication workflows.

What Is SigmaUNFOLD?

SigmaUNFOLD is an unfolding solution that interprets three-dimensional sheet metal parts, recognises bend features and generates accurate flat patterns using rule-based K-factor calculations. It processes individual parts or entire assemblies, enabling complete control over the unfolding workflow.

Unfolded parts can be manipulated directly within the SigmaUNFOLD interface for cutting and bending without the need to export and re-import files, which helps streamline programming and reduce manual effort. The software applies rule-based settings for K-factor, bend allowance and bend deduction values to support consistent flat pattern creation.

Frequently asked questions about SigmaUNFOLD

SigmaUNFOLD is a sheet metal unfolding solution that recognises bend features within three-dimensional sheet metal parts and converts them into accurate flat patterns. It is used to interpret 3D geometry and apply rule-based calculations to produce realistic flat layouts suitable for downstream manufacturing processes. The software can process individual parts or entire assemblies, making it suitable for environments where multiple sheet metal components must be flattened consistently and accurately.

SigmaUNFOLD generates flat patterns by recognising 3D bend features and applying rule-based K-factor, bend allowance and bend deduction calculations. These values determine how material stretches or compresses during bending, which directly affects the final flat shape. By applying configurable rules during the unfolding process, the software ensures that the generated flat pattern reflects realistic fabrication conditions rather than a simple geometric flattening.

Yes. SigmaUNFOLD is capable of processing individual parts, assemblies or even complete workspaces of sheet metal geometry. When assemblies are processed, the system recognises bend features across multiple components and unfolds them according to defined rule sets. This enables consistent flattening across grouped parts without requiring each component to be processed manually one at a time.

No. SigmaUNFOLD allows unfolded parts to remain within the same interface used for cutting and bending operations. This eliminates the need to export and re-import flat pattern files between different systems. By keeping the workflow within a single environment, users can manipulate and prepare flat parts directly without additional file conversion steps.

Yes. SigmaUNFOLD recognises complex 3D bend features, including multiple bends and closed shapes. The software is designed to interpret detailed sheet metal geometry rather than relying on simplified shapes. This ensures that flat patterns reflect the actual bend structure present in the original 3D model.

Yes. SigmaUNFOLD supports both interactive and non-interactive workflows, including batch unfolding commands. This allows multiple parts to be processed autonomously without requiring manual input for each individual component. Batch processing is particularly useful when large volumes of sheet metal parts need to be flattened efficiently.
