5. Open the File:
   • Select the STEP file (with a .step or .stp extension) and click the "Open" button.
6. Inspect the Model:
   • Once the file loads, you can explore the model in FreeCAD's workspace.

Practical Tips

• Ensure that the STEP file is not corrupted before attempting to open it.
• Familiarize yourself with FreeCAD's navigation tools for better model inspection.

Step 2: Exporting a Model as a STEP File

1. Prepare Your Model:
