Understanding IGES and CATPRODUCT file formats
IGES (Initial Graphics Exchange Specification, .igs or .iges) is a neutral file format used for exchanging 2D and 3D CAD data between different CAD systems. It is widely supported and ideal for sharing geometry, but it does not retain assembly structure or parametric data.
CATPRODUCT is the native assembly file format used by CATIA, a leading CAD software developed by Dassault Systèmes. CATPRODUCT files store assembly structures, including references to individual part files (CATPART), constraints, and relationships between components.
Why convert IGES to CATPRODUCT?
Converting an IGES file to a CATPRODUCT format is essential when you need to import geometry from a neutral format into a CATIA assembly. This allows you to integrate external parts or assemblies into your CATIA projects, maintaining assembly structure and enabling further design work.
How to convert IGES to CATPRODUCT
Direct conversion from IGES to CATPRODUCT is not a one-step process, as IGES files typically contain only geometry, not assembly data. The process involves importing IGES files as parts and then assembling them in CATIA:
- Open CATIA.
- Go to File → Open and select your IGES (.igs) file. CATIA will import the geometry as a new part (CATPART).
- Save the imported part as a CATPART file.
- To create an assembly, go to File → New and choose Product to create a new CATPRODUCT file.
- In the assembly window, use Insert → Existing Component to add your saved CATPART files to the assembly.
- Arrange and constrain the parts as needed, then save the assembly as a CATPRODUCT file.
Best software for IGES to CATPRODUCT conversion
The most reliable software for this conversion is CATIA itself, as it natively supports both IGES import and CATPRODUCT assembly creation. Alternative CAD software like Autodesk Inventor or Siemens NX can import IGES files, but only CATIA can create true CATPRODUCT files.
Tips for a successful conversion
- Check the IGES file for errors or missing geometry before importing.
- After import, verify that all features and surfaces are intact in CATIA.
- Organize imported parts logically in the CATPRODUCT assembly for easier management.
