This procedure describes the steps to follow to obtain a good quality 3D model for face.

1. On the main menu on the left, select Patients to open the menu.
2. Select New patient.
   By default, the name or ID of your patient is generated with the current date and time. You can edit it just by typing on it.
3. Select Face and Add patient.
4. Enter your patient's interpupillary distance.
5. Select Select photos to upload, one by one, the face photos.
   An operating system window opens to select the images stored in your device.
6. Upload the photos in the order described: Left, Front, Right.
   As soon as you upload a photo, the rotate-left and rotate-right icons are made available. Use them at your convenience until you get an upright photo. 
   If you uploaded the wrong photo or are not happy with it, use the Trash icon to remove it.
7. Select Create 3D.
   Wait until your 3D model is generated. This may take a while.
8. Analyse the quality and accuracy of the 3D model generated.
   For that, you can rotate the model sideways and up and down.
   1. Select No if you do not like the quality of the 3D model.
      Select new photos and upload them one by one and select Recreate 3D.
   2. Select Yes if you think the quality of the 3D model is good.
      Your screen is split in two: the "before" model is on the left, while, on the 3D model to the right, you can start with the simulation process.

You have created a face 3D model for a specific patient and can start with the simulation process.
