Convert ASM to SLDASM

Understanding asm and sldasm file formats

ASM files are assembly files commonly associated with CAD software like PTC Creo (formerly Pro/ENGINEER). These files store information about how individual parts (usually in PRT format) are assembled together, including constraints and relationships.

SLDASM files are SolidWorks Assembly files. They serve a similar purpose in SolidWorks as ASM files do in Creo, containing references to part files (SLDPRT) and defining their spatial relationships and constraints within an assembly.

How to convert asm to sldasm

Direct conversion between ASM and SLDASM is not natively supported by most CAD software, as these formats are proprietary and tailored to their respective platforms. However, you can transfer assembly data between Creo and SolidWorks using intermediate formats and import tools.

Recommended conversion method

1. Open your ASM file in PTC Creo.
2. Export the assembly using File → Save As → Save a Copy and select a neutral format such as STEP (.step, .stp) or IGES (.igs, .iges).
3. Launch SolidWorks and use File → Open to import the exported STEP or IGES file.
4. Once imported, use File → Save As and choose SLDASM as the target format.

This process preserves the assembly structure and geometry, though some constraints or features may require manual adjustment after import.

Best software for asm to sldasm conversion

• PTC Creo – for exporting ASM files to neutral formats.
• SolidWorks – for importing neutral files and saving as SLDASM.
• Autodesk Inventor and Autodesk Fusion 360 – can also import/export neutral formats if needed.

There are no reliable online converters for direct ASM to SLDASM conversion due to the complexity and proprietary nature of these formats. Using the official CAD software ensures the best results.

Summary

To convert ASM to SLDASM, export your assembly from Creo as a STEP or IGES file, then import it into SolidWorks and save as SLDASM. This method maintains assembly structure and is supported by leading CAD software.
