File: Product_Document_Scripts/Save_Child_Parts_To_STEP.py
Version: 1.2
Document Type: CATProduct

Exports all CATParts in an open CATProduct to individual STEP files. Files are saved to a subfolder named STEP_Export_ProductName alongside the product file. If the product has not been saved, files are exported to a subfolder in the user's Downloads folder.

Based on the pycatia user scripts example.

1. Open a CATProduct document containing CATParts
2. Run the script — no user input is required
3. All CATParts are exported to STEP files automatically

STEP files are saved to a folder alongside the product file:

ProductFolder\
 STEP_Export_MyProduct\
 Part1.stp
 Part2.stp
 Part3.stp

If the product has not been saved to disk yet, files go to:

C:\Users\YourName\Downloads\STEP_Export_MyProduct\

If STEP files with the same names already exist they will be overwritten.

• The product is put into Design Mode before export to ensure all parts are fully loaded
• All terminal nodes (leaf parts) in the product structure are activated before export
• Only files ending in .CATPart in the current CATIA document collection are exported
• The export folder is created automatically if it does not exist
