To Create a Grid of Points at Surface Elevations

Generates a grid of points that are automatically assigned surface elevations.

Specify grid base point (lower left corner), cell size (X and Y lengths), upper right corner, and optional rotation angle.

Because this command creates points using elevations from a surface, the Prompt For Elevations setting, specified in the Points Creation settings, does not affect how you are prompted during this command.

1. Select settings and create styles, layers, point groups, and description keys.
2. Click Home tabCreate Ground Data panelPoints menuCreate Points - SurfaceOn Grid.
3. Select a surface.
4. Specify the location of the grid base point, which is the lower left corner of the grid, by doing one of the following:
   • Enter X and Y coordinates on the command line.
   • Specify a point on the screen.
5. Enter the rotation angle or press Enter to accept the default.
6. Specify the grid X spacing by entering a value or pressing Enter to accept the default value.
7. Specify the grid Y spacing by entering a value or pressing Enter to accept the default value.
8. Specify the location of the upper-right corner of the grid by clicking on the screen.

   A single grid square and the outline of the entire grid are drawn on the screen.

9. Do one of the following:
   • To create the points based on the displayed grid, press Enter.
   • To change the grid, enter Yes and re-enter the rotation angle, grid base point, grid X spacing, grid Y spacing, and the upper right corner as previously described.

   The command calculates the coordinates of each grid point. The elevation of each calculated point is taken from the selected surface.

10. For each point, if prompted, enter the point name and description.

Note: Many factors affect how the point is displayed. For more information, see About Controlling the Appearance of Points in a Drawing.
