This function allows the user to create one or several section lines. Section lines are a series of intersecting lines of cut plane and finite element mesh and surfaces. The generated section lines will be included in the new part. By default, the section lines for different parts are included in discrete parts respectively; the finite element mesh and surface section lines of one part will also be included in discrete parts respectively. The user is allowed to define the rules for placing section lines and the name of the new parts in the Edit Default Config dialog box (refer to Section 11.5). After clicking on this function, the program will pop up a dialog box as shown in Figure 5.1.14.
Figure 5.1.14 Define section plane
CS: Select the current coordinate
system to define cut plane. The default option is the current coordinate system.
The user can select the defined local coordinate system from the list, or click
Define to create a new local coordinate system. Refer to Section 2.5 Local Coordinate System for
detailed description about defining LCS.
XZ-PLANE: Use a plane horizontal to the XZ-Plane to cut section line.
YZ-PLANE: Use a plane horizontal to the YZ-Plane to cut section line.
XY-PLANE: Use a plane horizontal to the XY-Plane to cut section line.
X-AXIS: Rotate XZ-Plane about X-Axis.
Z-AXIS: Rotate XZ-Plane about Z-Axis. Different
rotation axes appear if different coordinate planes are selected. For example,
the rotation axes of YZ coordinate plane are Y-Axis and Z-Axis, the rotation
axes of XY coordinate plane are X-Axis and Y-Axis.
Note: If LCS is selected, X-, Y- and Z-Axess are corresponding to U-, V- and W-Axes respectively.
ANGLE: Rotation angle value.
CLEAR: Hide or display the section and the object to be cut.
SELECT SURFACES: Select surfaces to be cut.
SELECT ELEMENTS: Select elements to be cut.
SELECT LOC: Select the
start point and end point. The value shown in the textbox is the relative
location between the selected point and the selected coordinate plane.
BY NUM: The number of section lines.
BY INC: The increment between section lines.
TOLERANCE: Enter a threshold value. The program will mark the section line deviation at the same location of surface and mesh according to this threshold value, and highlight all the locations where the deviation value is greater than the threshold value. If the deviation of point at the same location on section line is less than this threshold value, the greatest deviation value will be highlighted.
