Convert CATPRODUCT to CATPART

Understanding CATPRODUCT and CATPART file formats

CATPRODUCT and CATPART are proprietary file formats used by Dassault Systèmes' CATIA software, a leading CAD (Computer-Aided Design) application. CATPRODUCT files represent assembly files, which contain references to multiple parts and their relationships, while CATPART files are individual part files that store the geometry and features of a single component.

Why convert CATPRODUCT to CATPART?

Converting a CATPRODUCT (assembly) to a CATPART (single part) is often necessary when you want to simplify an assembly for downstream use, such as simulation, sharing, or manufacturing. This process is commonly referred to as creating a single solid part or shrinkwrap of the assembly.

How to convert CATPRODUCT to CATPART

The conversion is best performed within CATIA itself, as it natively supports both formats and provides robust tools for this operation. Here’s how you can do it:

1. Open your CATPRODUCT file in CATIA.
2. In the assembly tree, select the top-level product.
3. Go to Tools → Generate CATPart from Product.
4. Choose the desired options (such as merging all bodies or keeping them separate).
5. Save the resulting CATPART file.

This process creates a new CATPART file that contains the geometry of the entire assembly as a single part, which can be used for further operations.

Best software for CATPRODUCT to CATPART conversion

The most reliable and accurate way to convert CATPRODUCT to CATPART is by using CATIA itself. Third-party converters or viewers typically do not support this conversion due to the proprietary nature of the formats and the complexity of assembly data. If you do not have access to CATIA, you may consider contacting a service provider specializing in CAD conversions.

Key considerations

• Some assembly features, constraints, or references may be lost during conversion.
• The resulting CATPART is usually a single solid or a set of bodies, not an editable assembly.
• Always verify the geometry and integrity of the converted file before using it in production.
