This manual will mainly focus in the 2D (cephalometric) landmarking scene, however, how to load new AM photographs will be explained in the “Case selector” section.

Selecting the photograph work area

Using the “select work area” button we can cut out the specific area of ​​the photograph to work only with the face (Fig. 2). This cropping does not affect the proportions of the original image.

Auxiliary reference lines

After placing a cephalometric point, the vertical and horizontal auxiliary reference lines will be displayed (Fig. 5) and can be used to refine the marking. The lines can be moved by clicking on them and dragging the mouse. The inner circle can be used to rotate them.
