Property	Description
1.	Set the selection method as Rectangular, Radius, Diameter, or Polyline.
2. Adj (Adjacent)	Select faces adjacent to the seed face using an angle parameter. There are two angle options. See the combo box in label 8.
3. Faceset	Select an existing Faceset by using Faceset Picker.
4.	Add or remove a face. When the plus button is active, you can add faces by dragging a selection. When the minus button is active, you can remove faces by dragging a selection. When both buttons are deactivated, the selection mode will be changed to single selection. New selections are not added to the previous selection and selected faces are updated every time a selection is made.
5.	Select faces with orientation towards the screen. This works with both single and multiple selections. If this option is active, only faces with a normal direction towards the screen will be selected.
6.	Select the face nearest to the screen. When this option is active, only one face will be selected.
7.	Select all faces which belong to a body.
8. Edge Tangential/Face Normal Angle	Determine how to calculate the relative angle between two adjacent faces. This option is enabled when the Adjacent option (2) is selected. When Edge Tangential Angle is selected, the relative angle is calculated from two tangent vectors of adjacent faces as follows. When Face Normal Angle is selected, the relative angle is calculated from two normal vectors of adjacent faces as follows.
9. Angle	Set the angle parameter by entering the value directly or by using the slider bar. If the relative angle from 8 (above) is smaller than or equal to the specified angle, the face will be selected.
10. Face Filter	Set the geometry type filter to Any, Plane, Cylindrical or Spherical shape.
11. Face List	Display the list of selected faces.
12. Color	Select faces which have same color as the seed face.
