Convert IFC to NC1

Understanding IFC and NC1 file formats

IFC (Industry Foundation Classes) is an open, neutral file format widely used in Building Information Modeling (BIM) to facilitate interoperability between different software applications in the architecture, engineering, and construction (AEC) industries. IFC files store detailed 3D building and infrastructure data, including geometry, properties, and relationships.

NC1 (Numerical Control 1) is a file format used primarily in the steel fabrication industry. It contains machine-readable instructions for CNC (Computer Numerical Control) machines, such as drilling, cutting, and punching operations on steel profiles. NC1 files are essential for automating the manufacturing process of steel components.

Why convert IFC to NC1?

Converting IFC to NC1 is crucial for streamlining the workflow from BIM design to steel fabrication. By transforming 3D building models into machine instructions, fabricators can automate production, reduce errors, and improve efficiency.

How to convert IFC to NC1

The conversion process involves extracting relevant steel component data from the IFC model and generating NC1 files compatible with CNC machinery. This typically requires specialized software capable of interpreting BIM data and translating it into fabrication instructions.

Best software for IFC to NC1 conversion

• Tekla Structures: A leading BIM software for structural engineering, Tekla Structures offers direct export of NC1 files from IFC models. To convert, open your IFC file, select the steel components, and use File → Export → NC Files.
• Advance Steel: Autodesk Advance Steel supports importing IFC files and exporting NC1 files for fabrication. Use Output → NC & DXF → Create NC Files after importing your IFC model.
• IDEA StatiCa: While primarily for connection design, IDEA StatiCa can also process IFC files and export NC1 files for certain workflows.
• Online converters: Some online platforms, such as Steel Projects PLM and StruMIS, offer IFC to NC1 conversion as part of their cloud-based fabrication management solutions.

Tips for successful conversion

• Ensure your IFC model contains detailed and accurate steel component data.
• Check software compatibility with your CNC machinery's NC1 requirements.
• Review and validate the generated NC1 files before production to avoid fabrication errors.

Conclusion

Converting IFC to NC1 bridges the gap between BIM design and automated steel fabrication. Using specialized software like Tekla Structures or Advance Steel ensures accurate and efficient translation of building models into machine-ready instructions, optimizing the construction workflow.
