Examine2D > General Features
The Grid option allows you to display a grid of points or lines over the model. If the Snap option is enabled, the grid points can be "snapped" to. You may find this useful when adding boundaries, etc. The grid can also help you to estimate distances, and provide a sense of scale for the model.
To turn the grid on or off:
click on the GRID button on the Status Bar, OR
select the F7 function key, OR
toggle the Show Grid checkbox in the Grid Options dialog (see below)
Grid Options
Grid settings (Grid Style, Spacing, and Colour) can be changed in the Grid Options dialog. The Grid Options can be accessed in two ways:
select the Grid option from the View menu, OR
right-click on the GRID button on the Status Bar
NOTE: the grid will eventually "disappear" if you keep zooming "out" on a model. This prevents the grid from becoming so dense that it hides the model.
