Dear Admin, Hi
Please consider a situation that having 2D lines, poly lines or polygons and a raster elevation data.
How can i extract elevation for 2D data from DEM?
Is there an option in GM to add additional vertices?So the 2D data to show the surface along the line better and more smooth and accurate?

You can add Z values to each vertex by selecting the features with the Digitizer tool, then use the Measure/Analyze right-click option to add elevations from the loaded terrain layers. If you want more vertices, first use the Move/Reshape right-click menu command to resample the features at a smaller spacing, then apply the elevations.
Thanks,
