Cross sections - also referred to as fence diagrams - are flat surfaces used to visualize the subsurface. GMS has different types of cross section objects:

Solid Cross Sections

Solid cross sections can be created by "slicing" through a set of solids using the Create Cross Section tool. This can be done at any angle and the slicing can be done using a multi-segment polyline. Solid cross sections can be converted to a conceptual model. This is useful if you have a solid model of an embankment that you want to analyze using UTEXAS.

Example of fence diagrams created using solids

Borehole Cross Sections

Borehole cross sections are quite different than solid, 3D grid, and 3D mesh cross sections. See the page on Borehole Cross Sections.

3D Grid Cross Sections

3D grid cross sections are created similar to solid cross sections. Data sets are automatically interpolated from the 3D grid to the cross sections and contours can be displayed on the cross sections.

3D Mesh Cross Sections

3D mesh cross sections are created similar to solid cross sections. Data sets are automatically interpolated from the 3D mesh to the cross sections and contours can be displayed on the cross sections.

Cross-Section Options

When cross sections are created from a mesh or a grid, values of the active scalar and vector data sets are interpolated to the cross sections. Whenever a new data set is chosen as the active data set for the mesh, the data values are re-interpolated to the cross sections.

The properties of all cross section data that GMS displays on the screen can be controlled through the Cross Sections tab of the Display Options dialog. This dialog is opened by right clicking on the File:CrossSectionFolder.GIF Cross Sections entry in the Project Explorer and selecting the Display Options command. It can also be accessed from the from the Display menu or the File:Dispopts.gif Display Options macro. The following table describes the display options available for the cross sections.

Display Option Description
Interior edge removal By default, the lines representing the intersection of the cross section with the faces of the cells or elements are displayed on the cross section. These lines can be hidden by selecting the Interior edge removal option.
Cross section edges If this option is on, the lines that make up the cross section are displayed.
Cross section faces If this option is on, then the cross section will be displayed as a set of filled polygons.
Contours If the Contours item is selected, contours are displayed on the cross sections using the active scalar data set.
Vectors If the Vectors item is selected, vectors are displayed on the cross sections using the active vector data set when the cross sections are displayed.
Flow trace If the Flow trace item is selected, a flow trace image is texture mapped to each cross section using the active vector data set when flow trace option is used with the Animation wizard.
