      <p class="para_topic">Complex Section allows you to create cross-sectional curves using multiple section planes. Unlike Simple Section, the resulting cross-sectional curves in Complex Section do not necessarily lie in the planes used to create the cross-section. Instead, the cross-sectional curves are rotated about a specified axis onto the specified projection plane.</p>

      <p class="para_division">After selecting the Complex Section button, the Body, Axis, Projection Plane, and Section Plane Definition Step buttons become available.</p>
      <p class="para_division">First, select all of the solid bodies to be sectioned. Next, define the axis. The default axis is the MCS X-Axis. The section curves will rotate about this axis onto the projection plane using the Right-Hand Rule of Rotation. In other words, if you point the thumb of your right hand in the direction of the displayed axis vector, the section curves will rotate onto the projection plane in the direction of your fingers.</p>

      <p class="para_division">After defining the axis or accepting the MCS X-Axis default (no interaction required to accept default), select the projection plane button. The default projection plane is the MCS XY-Plane. Selecting Specify Plane allows you to define any plane as the projection plane using the Plane Subfunction.</p>

                  <p class="para_note_body">Later, when you use these cross-sectional curves to create boundaries, remember that the boundary will be created by projecting the selected section curves from the projection plane onto the boundary plane (usually the XC-YC plane). You should define the projection plane using the default MCS XY-Plane which coincides with the default XC-YC boundary plane. By doing this, the section curves will be created in the same plane as the boundary, and like the section curves, the boundary will represent a true cross-section of the Part.</p>

      <p class="para_division">After defining the projection plane or accepting the MCS XY-Plane default (no interaction required to accept default), select the Section Plane button. The default section plane is the MCS XY-Plane. Selecting Specify Plane allows you to define section planes using the Plane Subfunction. Use Radial Planes allows you to define section planes by keying in angles. Once you have defined the section planes, select Apply to generate the cross-section curves.</p>
