Importing OBJ files into ArtCAM is a straightforward process that allows you to use 3D models in your designs for CNC machining. To begin, open ArtCAM and navigate to the File menu. Select 'Import' and choose the OBJ file that you want to import. Once selected, you can adjust the import settings to customize the scale and positioning of the model within your design. After finalizing the settings, click 'OK' to import the OBJ file into your ArtCAM project. You can then use the imported 3D model as part of your design and prepare it for CNC machining. By following these simple steps, you can seamlessly integrate OBJ files into your ArtCAM projects and enhance your 3D modeling and CNC machining capabilities.
