Convert SLDASM to ASM

Understanding sldasm and asm file formats

SLDASM is the file extension for SolidWorks Assembly files, which are used to store 3D assembly data in Dassault Systèmes' SolidWorks CAD software. These files reference multiple part files (SLDPRT) and contain information about the assembly structure, constraints, and relationships between components.

ASM files are assembly files used by various CAD programs, most notably PTC Creo (formerly Pro/ENGINEER). The ASM format stores assembly data, including the arrangement and constraints of parts, but is not natively compatible with SolidWorks.

Why convert sldasm to asm?

Converting SLDASM to ASM is often necessary when collaborating between teams using SolidWorks and PTC Creo. This conversion allows assemblies created in SolidWorks to be opened, edited, and managed in Creo, facilitating cross-platform engineering workflows.

How to convert sldasm to asm

Direct conversion from SLDASM to ASM is not natively supported in most CAD software. However, you can use intermediate neutral formats such as STEP (.step, .stp) or IGES (.igs, .iges) to transfer assembly data between SolidWorks and Creo.

1. Open your assembly in SolidWorks.
2. Go to File → Save As.
3. In the Save as type dropdown, select STEP (*.step, *.stp) or IGES (*.igs, *.iges).
4. Click Options to adjust export settings if needed, then click Save.
5. Open PTC Creo.
6. Go to File → Open and select the exported STEP or IGES file.
7. Once imported, save the assembly as an ASM file using File → Save As.

Best software for sldasm to asm conversion

• SolidWorks – for exporting SLDASM to neutral formats like STEP or IGES.
• PTC Creo – for importing neutral files and saving as ASM.
• Autodesk Inventor and Autodesk Fusion 360 – can also be used as intermediaries for file conversion if needed.

For batch conversions or automation, consider using CAD Exchanger or TransMagic, which support a wide range of CAD formats and can streamline the process.

Important tips

• Always check assembly integrity after conversion, as some constraints or features may not transfer perfectly.
• Use the latest versions of both SolidWorks and Creo for best compatibility.
• Consider sharing both the assembly and all referenced part files to avoid missing components.
