The right figure shows the gradation contour for a cross section and a surface.

 

Operations

There are types of operations; Simple mode and Detailed mode.

Simple mode is limited to XY, YZ, and ZX planes for easy operation.

Detailed mode can display a cross section by specifying a point and a normal vector on the cutting plane. Multiple cross sections can be shown as well. Also, the cross section and the surface are displayable simultaneously.

 

Simple Mode

 

XY, YZ, or ZX plane

Sets the cutting plane on XY, YZ, or ZX plane.

Cutting plane X, Y, or Z coordinate

Sets the location of the cutting plane. Coordinates of the center of the model are set by default.

Close button

Closes the dialog box if clicked.

Preview

Previews the cross section in the operation of the cutting plane if clicked.

 

Create

Creates the cross section if clicked.

 

Reset

Resets the location and normal direction of a cross section to their default values. if clicked.

 

 

Detailed Mode

 

How to set up the cutting plane

Sets the [Direction of Cutting Plane] and the [Point on Cutting Plane].

Face

Aligns the direction of the cutting plane to the direction of the face selected in the result window.

Reverse Direction

Reverses the direction of normal vector.

When the cross section and the surface are displayed, the surface in the normal vector's positive direction will be displayed.

Its direction can be changed by this button.

Selected Bodies

Moves the cutting plane to the center of the body selected in the result window.

Maximum Point/Minimum Point

Moves the cutting plane to the point where the field value displayed on the result window is maximum or minimum.

Arrangement

Display the cross section and the surface simultaneously (vectors are only for cross section): The cross section and the surface in the normal vector’s positive direction are displayed simultaneously.

Display without cutting meshes on the cutting plane: Mesh elements on the cutting plane are not cut. Their forms are kept.

 

Remove meshes on the cutting plane: The portion of the mesh elements crossing the cutting plane are removed. The element forms are kept.

 

 

Preview

 

Enable Preview: Switches on/off preview of the cross section.

Guide Grip On: Switches on/off grids used during preview.

Distance: Sets the unit grid for translation

Angle: Sets the unit grid for rotation.

Operations

Create: Creates a cross section. If a cross section already exists, it will be replaced by the created one.

Add: Adds a cross section to the existing sections. Multiple number of sections can be displayed.
Not selectable if [Display without cutting meshes on the cutting plane] or [Enable Preview] is selected.

Delete: Deletes a specified cross section.

Stop Update of Max and Min on Color Scale

If selected, the range of max and min on the color scale will not be updated in creating a cross section.

The distribution of the field value at the cross section can be checked in contrast to the whole model.

 

 

 

How to Use UI for Preview

 

If the Cross Section dialog box is enabled, the translation and rotation axes appear as in the left figure.
The default cross section is in the direction of ZX plane.

The translation or rotation axis is selected with the mouse to translate or rotate the cutting plane to the desired location.
If the axis is selected again, the translation or the rotation will restart from that position.

If [Enable Preview] is deselected in the dialog box, the cross section process will be carried out in clicking the [Create] button.

If [Enable Preview] is selected, the cross section is created for every operation of cutting planes.

 

  1. The unit of translation or rotation of the cutting plane is set with the distance or angle of the Guide Grid On on the cross section dialog box.
     

  2. The points on the cutting plane and the direction of the cutting plane on the cross section dialog box are applied to the cross-section UI.
     

  3. If you right click without any cross selection, the sectioning process will be terminated.
