Specify which field contains elevation information in the Select Field dialog. |
For 2D polylines and polygons, click the current attribute in the Select the field containing the contour elevations field and select the desired attribute from the list.
With 3D polylines and 3D polygons, check the Use Z coordinate for 3D geometry check box to use the Z coordinate, or unclick the Use Z coordinate for 3D geometry and select the attribute to use from Select the field containing the contour elevations.
To ignore 2D objects when both 2D objects and 3D objects are present, set Select the field containing the contour elevations to [None].
If both Use Z coordinate for 3D geometry is checked and an attribute is selected, 3D objects will use the Z coordinate and the 2D objects will use the attribute. For 3D objects, the Z coordinate always takes precedent.
Click OK when you have selected the desired field.
Click Cancel to return to the Grid Contours dialog without selecting the elevation field. If you click Cancel the map layer or vector file will not be loaded.
