Section cuts are useful for obtaining the resultant forces which act within a specified section-cut plane.
Each of these section-cut types may be implemented through the procedures described in the following sections:

1. Define a quadrilateral cutting plane
- Select Quadrilateral Cutting Planes, then define the plane by specifying its joint coordinates, as shown in Figure 1:

- Once analysis is run, section-cut forces are available in tabular format by selecting Display > Show Tables > Analysis Results > Structure Output > Other Output Items > Table: Section Cut Forces - Analysis, as shown in Figure 2:

2. Define a group
Section cuts may also be defined by specifying a group of structural objects. Here, section-cut forces represent the sum of joint forces within those frame, shell, and link objects which are included in the group. As shown in Figure 2, the Section Cut Group must include All joints for which forces should be summed.

3. Draw the section cut within the graphical user interface
Section cuts may be drawn within the graphical user interface by selecting Draw > Draw Section Cut. Section-cut forces will then be displayed on the Section Cut Forces and Stresses form shown in Figure 3:
