Field Point Grid
The Field Point Grid is a regular grid of points in the Plan View which defines a grid of vertical strings in 3-dimensions. The settlement analysis results are computed at intervals along each string, and used to generate contours of settlement, stress and pore pressure in a horizontal plane at any depth.

Field Point Grid: Properties
The grid can be automatically generated with the Auto Grid option, or can be manually located with the Add Grid option. The number of grid points and the autogrid expansion factor can be customized in the Grid Properties dialog. Increasing the number of grid points will improve the accuracy of the contours but will increase computation time.

Field Point Grid: Depth Control
The contour plane at any depth can be interactively displayed using the depth control in the sidebar. You can type in a value of depth, or drag the vertical slider control, and the onscreen results will be immediately updated. You can also click and drag directly on the edge of the contour plane in the 3D view to change the depth.

Field Point Grid: Contours
The contour values are displayed in the Contour Legend in the sidebar. The contour style, range, and number of intervals are fully customizable in the Contour Options dialog.
Contour Legend
The field point grid contours can be displayed as a 3-dimensional deformed surface by selecting the Deformed Contours checkbox in the sidebar.

The vertical deformation of the contour data can be magnified by a user-defined scale factor entered in the Display Options dialog.
