You'll need an .stl or obj file of your patient. The Galileo Scanner App produces .obj files. 2. You'll begin submitting an order as normal, select the paperclip to attach your scan, then select Galileo CAD after it uploads. 3. Or you can launch GalileoCAD from the left sidebar, select your file from the list, and export your CAD file to your file list for an order. ![download 21](https://www.help.protosthetics.com/hs-fs/hubfs/download%2021.jpeg?width=670&height=152&name=download%2021.jpeg)   ![galCAD](https://www.help.protosthetics.com/hs-fs/hubfs/galCAD.png?width=554&height=309&name=galCAD.png) ### Designing a Transtibial Check Socket in Galileo CAD #### 1. Import the Scan - Open the Galileo CAD software and select **Import Residual**. - Locate and select the desired patient scan file (e.g., "test patient") to pull the 3D model into the workspace. This file type can be either an **.OBJ or .STL** #### 2. Model Preparation - Navigate to the **Model Preparation** section to orient the scan. - Select the MPT (Mid-Patellar Tendon) and the distal end on the 3D model to help the software establish an initial orientation. ### ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Oct-23-2026-07-28-43-5220-PM.png?width=670&height=369&name=image-png-Oct-23-2026-07-28-43-5220-PM.png) - Adjust the cut-off length if needed; leave it at a higher value (e.g., 300mm) if you want to retain the entire scan without cutting off material.   ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Oct-23-2026-07-29-11-2145-PM.png?width=670&height=371&name=image-png-Oct-23-2026-07-29-11-2145-PM.png) - Fine-tune the orientation by clicking and holding the blue, red, or green rotation circles to tilt the model anteriorly/posteriorly or medially/laterally until it is properly aligned. ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Oct-23-2026-07-29-38-0302-PM.png?width=670&height=380&name=image-png-Oct-23-2026-07-29-38-0302-PM.png) - *(Optional)* Use the **Extend Scan** tool to artificially extend the model proximally (upward) beyond the original scan boundaries by adjusting the slider. #### 3. Landmark Points - Go to the **Landmark Points** section to place anatomical reference points. - The software will attempt to auto-generate points, but you must manually adjust them by dragging them to their correct anatomical locations. - Adjust the **Patella Center**, **Mid Patella Tendon**, **Distal Tibia**, and the **Distal End** points. - Rename any "Unnamed" landmarks by clicking the pencil icon; for example, rename one to "Fib Head" (Fibular Head). ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Oct-23-2026-07-30-26-6353-PM.png?width=1451&height=752&name=image-png-Oct-23-2026-07-30-26-6353-PM.png) - Toggle **Color Mode** on to view any physical markings drawn on the patient's liner or skin during the physical scan, allowing for precise landmark placement. #### 4.  Reductions (Volume Modification) - Navigate to the **Reductions** tab to adjust the overall volume. - To apply a global reduction, select **Single Value** and input a percentage (e.g., 2%) to uniformly shrink the socket. - Manage **Holdback Regions** (areas excluded from reduction, such as the tibial crest, fibular head, or distal end). - If you want the entire socket reduced uniformly without excluding any areas, delete all regions from the holdback list. #### 5.  Modifications (Build-ups and Compressions) - Open the **Modifications** section to apply custom shape modifications. - **Color coding:** Blue shapes represent reliefs (build-ups), while red shapes represent compressions. - Select a modification (e.g., Patella Tendon Bar) and adjust its depth (e.g., reducing from 10mm to 4mm) and its **Edge Blend Amount** (e.g., 10mm) for a smooth transition into the socket wall. - Manually alter the shape of the modification by clicking and dragging the individual control points on the model (e.g., widening the patella tendon bar to create a "smile" shape). ![8-1](https://www.help.protosthetics.com/hs-fs/hubfs/8-1.png?width=670&height=372&name=8-1.png) - To move an entire modification region at once, highlight the lines until they turn milky white, then click and drag. ![9](https://www.help.protosthetics.com/hs-fs/hubfs/9.png?width=670&height=376&name=9.png)![10](https://www.help.protosthetics.com/hs-fs/hubfs/10.png?width=670&height=366&name=10.png) - Add, modify, or delete specific reliefs and compressions (like distal tibia relief or lateral compression) to fit the patient's anatomy. ![7-2](https://www.help.protosthetics.com/hs-fs/hubfs/7-2.png?width=670&height=382&name=7-2.png) #### 5.  Trimline Design - Go to the Trimline tool. - Toggle Transparency on to see all landmarks simultaneously, and set the view to Orthographic to ensure perfect symmetry. ![11](https://www.help.protosthetics.com/hs-fs/hubfs/11.png?width=670&height=435&name=11.png) - Adjust the auto-generated trim line by clicking and dragging the existing points. ![12](https://www.help.protosthetics.com/hs-fs/hubfs/12.png?width=670&height=374&name=12.png) - Add new control points to the line to create custom shapes, such as a "W" style relief (swoops) on the medial and lateral condyles. ![13](https://www.help.protosthetics.com/hs-fs/hubfs/13.png?width=670&height=375&name=13.png) - Apply a **Proximal Build-up** (e.g., 8mm) to generate an artificial flare extending above the trim line, which aids the designers in preparing the final print. ![14](https://www.help.protosthetics.com/hs-fs/hubfs/14.png?width=670&height=376&name=14.png) #### 7. Freehand Tools & Global Smoothing - *(Optional)* Use **Freehand Tools** for individualized smoothing or adding localized build-ups to specific patches of the model. - *(Optional)* Navigate to **Global Smooth** and set a radius (e.g., 3mm) to automatically smooth out any rough or patchy areas across the entire model. #### 8. Export - Navigate to the **Export** section and click **Export Modified Residual**. - This generates a finalized CAD file containing all trim lines, build-ups, and reductions,. This is added to your file list and can be attached as part of your Galileo order. - Reminder to choose the Modified CAD scanned medium when attaching your final CAD fille! ### Congrats on your design - we hope you enjoy Galileo CAD! - [Account & General Information](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#main-content) - [Account & Permissions](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#account-permissions) - [Policies & Guarantees](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#policies-guarantees) - [Printer Returns](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#printer-returns) - [Scanning Options](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#main-content) - [App & Hardware Setup](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#app-hardware-setup) - [Scanning Best Practices](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#scanning-best-practices) - [Ordering Process & FabOne Portal](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#main-content) - [Placing & Managing Orders](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#placing-managing-orders) - [Print Control](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#print-control) - [CFAB Options](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#cfab-options) - [Galileo Product Options](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#main-content) - [Prosthetic Products](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#prosthetic-products) - [Orthotic Products](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#orthotic-products) - [Customization & Fitting](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#customization-fitting) - [Filament & Printing FAQs](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#main-content) - [Filament Loading & Handling](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#filament-loading-handling) - [Preparing the Printer](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#preparing-the-printer) - [Hardware Troubleshooting & Maintenance](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#main-content) - [General Tips & Tricks](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#general-tips-tricks) - [Connection Troubleshooting](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#connection-troubleshooting) - [Hardware Troubleshooting - Pro](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-troubleshooting-pro) - [Hardware Maintenance - Pro](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-maintenance-pro) - [Hardware Troubleshooting - Galileo O&P/Pro 2](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-troubleshooting-galileo-op-pro-2) - [Hardware Maintenance - Galileo O&P/Pro 2](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-maintenance-galileo-op-pro-2) [![ProtostheticsGalileo Logo-1](https://www.help.protosthetics.com/hubfs/ProtostheticsGalileo%20Logo-1.svg "ProtostheticsGalileo Logo-1")](http://protosthetics.com) 510 6th Ave N, Ste D, Fargo, ND 58102 USA [mailto:success@protosthetics.com](mailto:success@protosthetics.com) Copyright © 2026, Protosthetics
