Convert CATPART to SLDASM

Understanding CATPART and SLDASM file formats

CATPART is a proprietary 3D part file format used by CATIA, a leading CAD software developed by Dassault Systèmes. It stores detailed information about a single 3D part, including geometry, features, and parameters.

SLDASM is the assembly file format for SolidWorks, another popular CAD application. SLDASM files reference multiple part files (SLDPRT or imported formats) and define their spatial relationships, constraints, and assembly structure.

Why convert CATPART to SLDASM?

Converting a CATPART to SLDASM is necessary when you need to use a CATIA part within a SolidWorks assembly. Since SLDASM is an assembly file, the process typically involves importing the CATPART into SolidWorks and then saving or adding it as a component in a new or existing assembly.

How to convert CATPART to SLDASM

1. Open SolidWorks on your computer.
2. Go to File → Open and select your CATPART file. SolidWorks supports direct import of CATIA V5 files (CATPART) in most recent versions.
3. Once the part is open, create a new assembly by selecting File → New → Assembly.
4. Insert the imported part into the assembly using Insert Components.
5. Save the assembly by choosing File → Save As and selecting SLDASM as the file type.

Best software for CATPART to SLDASM conversion

The most reliable software for this conversion is SolidWorks itself, as it natively supports CATPART import and SLDASM creation. For batch conversions or more complex scenarios, consider using 3DEXPERIENCE or CATIA Composer in conjunction with SolidWorks, or third-party tools like TransMagic or Datakit CrossManager for advanced interoperability.

Important notes

• Direct conversion from CATPART to SLDASM is not possible without first importing the part into an assembly environment.
• Some features or parametric data may not transfer perfectly due to differences in how CATIA and SolidWorks handle geometry and features.
• Always verify the imported geometry and assembly structure after conversion.
