How to Add 3D Model to Footprint in Altium

Altium Designer, a powerful Electronic Design Automation (EDA) software, is favored by many engineers for its robust features and user-friendly interface. When designing printed circuit boards (PCBs), incorporating 3D models allows engineers to perform visual inspections, ensuring design accuracy and feasibility. This article provides a detailed guide on how to add 3D models to footprints in Altium Designer, helping you enhance your PCB design process.

　　I. Preparation

　　Before you begin, gather the following tools and resources:

　　1. Altium Designer: Ensure you have the latest version installed.

　　2. 3D Model Files: Typically in STEP format (.step or .stp).

　　3. 3D Modeling Software (e.g., Blender): Used to create or edit 3D model files.

　　II. Creating or Downloading 3D Models

　　Start with obtaining a 3D model file. For high-quality textures and HDRI, or to download 3D models, Relebook offers a resource for importing textures and 3D models directly into the model.

　　III. Adding 3D Models to Footprints in Altium

　　1. Open Altium Designer:

　　Launch Altium Designer and open your PCB project.

　　2. Create a New Footprint (or Edit Existing):

　　- In the "PCB Library" panel, select the "File" menu and click "New Component" to create a new footprint, or right-click on an existing footprint and choose "Edit".

　　3. Import the 3D Model:

　　- In the footprint editor, select the "Place" menu and click "3D Body".

　　- In the dialog that appears, choose "Generic 3D Model".

　　- Browse and select your STEP file to import, then click "Open".

　　- The 3D model will be imported into the footprint; use the mouse to drag and position it appropriately.

　　4. Adjust the Position and Orientation of the 3D Model:

　　- Use the "Move" tool from the toolbar to adjust the position of the 3D model.

　　- Use the "Rotate" tool to rotate the 3D model to align with the physical dimensions and position of the footprint.

　　- For precise adjustments, enter specific values in the properties panel.

　　5. Save the Footprint:

　　- Once adjustments are complete, save the footprint and close the editor.

　　- The new 3D model is now successfully added to the footprint and ready for use in your PCB design.

　　IV. Using 3D Footprints in PCB Design

　　1. Add Footprint to Schematic:

　　- Open the schematic editor, select the "Place" menu, and click "Component".

　　- Browse the library to find the footprint you just created or edited, and place it on the schematic.

　　2. Synchronize Schematic and PCB:

　　- In the schematic editor, click the "Design" menu and select "Update PCB Document".

　　- In the PCB editor, accept all updates to add the new 3D footprint to the PCB design.

　　3. Check the 3D View:

　　- In the PCB editor, click the 3D button in the upper right corner to switch to 3D view.

　　- Ensure the new 3D model displays correctly and verify its relative position with other components.

　　V. Optimization and Considerations

　　1. Model Size and Scale: Ensure the imported 3D model's size and scale are accurate. If the model is too large or too small, adjust it in the 3D modeling software before re-importing.

　　2. Model Simplification: For complex 3D models, consider simplifying them in the modeling software to reduce rendering burden in Altium, improving operational smoothness.

　　3. Footprint Validation: After design completion, conduct physical validations to ensure consistency between the 3D model and actual components, avoiding issues during manufacturing.

　　By following these steps, you can seamlessly integrate 3D models into footprints in Altium Designer, enhancing design accuracy and visual representation. Relebook provides resources for importing textures and 3D models directly into the model, useful when creating models and virtual scenes.
