Convert SLDASM to NC1

Understanding sldasm and nc1 file formats

SLDASM is the file extension for SolidWorks Assembly files, which are used to store 3D assembly models created in SolidWorks, a popular CAD (Computer-Aided Design) software. These files contain references to multiple part files (SLDPRT) and define how these parts fit and move together.

NC1 files are used in the steel fabrication industry and contain machine-readable instructions for CNC (Computer Numerical Control) machines, specifically for beam drilling, punching, and cutting. The NC1 format is based on the DSTV standard and is widely used for structural steel detailing and manufacturing.

How to convert sldasm to nc1

Direct conversion from SLDASM to NC1 is not straightforward, as SLDASM files are assemblies and NC1 files are manufacturing instructions for individual steel parts. The typical workflow involves exporting individual parts from the assembly and then generating NC1 files for those parts.

1. Open your assembly in SolidWorks.
2. Export the required part(s) as STEP or IGES files:
   • Go to File → Save As and choose STEP (*.step, *.stp) or IGES (*.igs, *.iges).
3. Import the exported part file into a steel detailing software that supports NC1 export, such as Tekla Structures or Advance Steel.
4. In the detailing software, assign material and profile information as needed.
5. Export the part as an NC1 file:
   • For Tekla Structures: File → Export → CNC and select DSTV (NC1) as the format.
   • For Advance Steel: Output → NC & DXF and choose NC1 as the output format.

Best software for sldasm to nc1 conversion

• Tekla Structures: Industry-leading BIM software for steel detailing, supports direct NC1 export.
• Autodesk Advance Steel: Powerful steel detailing tool with robust NC1 export capabilities.
• SolidWorks (with add-ins): Some add-ins or partner solutions may allow direct export to NC1, but typically an intermediate step through detailing software is required.

Summary

To convert SLDASM to NC1, export the assembly's parts to a neutral CAD format, import them into steel detailing software, and then export as NC1. Tekla Structures and Advance Steel are the best tools for this workflow.
