The iScan software has an Undercut Analysis feature which you can use to calculate the undercut region by setting the insertion direction or by using the Auto Direction function.
- Go to the Tools section and click the Undercut Analysis button.
- In the Command Option area, you will see the following selection tools.
Brush: Selects all entities on a freehand-drawn path on the screen. The brush comes in 3 different sizes.
Polyline: Selects all entities within a polyline shape drawn on the screen.
Circle: Selects all entities within a circular area.
Clear Selected Area: Clears areas selected by a drawn path. The brush comes in 3 different sizes.
Clear All Areas: Clears all selected areas.
- Set the region of interest to calculate the undercut area using the selection tools.
- Once you’ve selected the area, click Auto Direction or Manual Direction. These are the two different methods to set the insertion direction.
Auto Direction: The system automatically calculates the direction in which the undercut area is minimized, then displays the undercut area on the View screen.
Manual Direction: The system calculates the undercut area based on the direction specified by the user, then displays the undercut area on the View screen.
