Watch the short video and learn how this works.
Intra-oral scans, scans without sectioned dies, or virtual dental models will need to be sectioned first. This is done so the tooth margins can be clearly marked without neighbouring teeth causing interference.
Select the scan then use the 'Top View' or the 'Bottom View' buttons so you can view the teeth from above or below. After this, press the 'Create a Vertex' button.
Use G to position the vertex, then use E to extrude the vertex into a line. Left click to set down the vertex. Use Shift D, to duplicate the vertex to start a new cut, then G to move the duplicate vertex into a new position. Repeat the process to create another cut line.
Next, press the 'Make Cutting Tool' button. The separation has a default value which can also be adjusted.
The tool will be displayed in an orange colour with a clearance space in between. Set your clearance.
Press the 'Section Scan/Model' button which will create the separation.
This function works with the 'face orientation' feature in case the normals become turned inside out. If the scan is red on the outside, please use the 'Flip Normals' tab on the menu. The outside surface of the scan must always be blue. This goes for all sections. Use the check box to view the case in Object mode again.
