This enables Avontus Viewer to accurately superimpose the Augmented Reality version of the Scaffold over the printed drawing. To prepare a drawing for scale model Augmented Reality: 1. Open the appropriate Avontus Designer drawing. 2. Click the **AR Base Point** drawing object and drag it to the lower left corner of the drawing border. (The AR Base Point can be placed at any point that is easily referenced on the printed page. If no AR Base Point is added to the drawing, the center of the model will be used.) ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/b313ca5b-af97-45b9-bc4e-39ead449728b.png) 3. Save the drawing, then upload it to Avontus Viewer. (For those procedures, refer to *[Uploading a Scaffold VR Mode](https://docs.avontus.com/docs/uploading-a-video-of-an-avontus-viewer-model)*.)
