Draw Contours from Grid Model

Use this function to generate a contour map based on a grid model.

Run the function from:

MOUS_ICO Toolbar: Not available from the Toolbar

MOUS_ICO Menu: Novapoint > Terrain Information > Draw Contours from Grid Model

KEYB_ICO Command Line: Not available from the command line

The dialog box Contours from Grid Model will pop up.


Selecting the contour generation project file, grid file, and boundary line are defined on this tab. Use Browse… to select the grid file.

The Preview function can generate Contours, Contours with color, and Grid with color, so you can check the result before drawing to AutoCAD.

With Terrain/Elevation, you can select one of the levels for which that contour map is to be generated. E.g., if the grid file contains level 0 and level 1, select level 0 to generate a contour map of level 0 and level 1. Select level 1 to generate a contour map for level 1 alone.


To employ boundary settings, mark the check box 'Use Boundary'. The following methods can be used:

Note: All setup information will be saved to the project file.


Settings such as contour interval, limits of contour generation, draw options, and preview are defined on this tab.

Calculation settings

The contour map can be restricted using the minimum and maximum elevations.

The interval of the contour is classified as contour line and index contour line.

Elevation in the grid file

The minimum and maximum elevation values of the data in the grid model (selected on the tab 'Common') will be displayed in the respective fields.

AutoCAD settings

Setting for the AutoCAD drawing with the desired 'Layer' for the 'contour line' and line type under 'Layout'. Wanted 'Layer' for the 'text' and type of text under 'Layout'.
