If this is this what you wanted. Keep your site model and stake objects on the same design layer, then set your stake label to coordinates.

If you are using Leica ICON, exporting the 3D polygon as a dxf or dwg will be recognized as a surface dtm. I don’t if it’s the same for Topcon

Hi Giulio, The reason why you have those openings instead of a closed solid, is because your mesh is overlapping it's self in the corners. I would suggest breaking it up in two parts; use a a extruded polygon for the top section use subdivision for what's underneath. Then, you can convert the Sub to a mesh and do a solid add with the polygon. From this point everything should subtract as expected.

Hi Giulio, Could you post the subdivision, If you don't mind. I would like to see how that happened. Because when you subtract solid you should not have gotten the result shown.

Hi Giulio if you to convert the Subdivision to a Mesh first, you should be able to as Hans-Olav stated. That is what I have done here.

My issue is that I created a Data tag, to display the size of a concrete beam. The tag was set to show the Major breath and depth. My document units are set to feet but the data tag is displaying everything in millimeters. This is what I used in the Tag "#StructuralMember#.#D#X#StructuralMember#.#B#". How can I get it to display 3' instead of 914.40000?

Select both nurbs and convert to mesh, set the fill to solid. Then use the push pull tool to extrude the mesh.
