Dear all,
I have ~50 manholes with no groundlevel. How can I add data from my DEM raster (digital elevation model)? Which method do you suggest?
Thanks for help,

Try "[b]Interpolation and assignment[/b]" tool, you can find it under [b]Tools[/b]

press [b]next[/b] and select the layer you want to change, in your case [b]MOUSE Manholes[/b] and attribute would be [b]GroundLevel[/b].

press next and select "[b]Assign from raster cells[/b]" and then see if you can locate your DEM file in the listmenu, the first one of the two. If so, continue and check the second listmenu and select "[b]pixel value[/b]"

Continue and from there you have one more window with options, if i'd change all manholes i'd keep every box unselected.

Thanks a lot! I knew it was there somewhere, but I just could not find it. It is a very useful tool.
