If you load your data into qgis you can prepare your data to creating kmls. I'm not sure what attributes are in your dataset, and how are they separated, but maybe after to load them into qgis you need to do some additional steps, like merge, or calculation fields and then you can export your dataset separated by materials and their depth plus the surface ...

If you already have or can create the line itself as a 3D entity (ie with z values), the Feature to Raster tool can use the z value in creating the raster. You could also use the points to create a raster via interpolation, and then use Extract by Mask to pull out just the cells along the line. Not sure if that will take a line as a mask, but if not you ...

Please try to change the second part of the SQL-Statement: e.g. update lidar_pts set z= st_z(GEOMETRY) It worked fine for me with mulitpart-points - documented here http://isticktoit.net/?p=1117

You can use the Integrate tool to insert a vertex at the intersection the two lines. Just make sure your contour dataset has a lower rank and your blue line datasets is Z aware. The Integrate tool does not honour the Z value (I checked this on some sample data) so you would then need to update the Z property of the inserted vertex. Now at this point I'm ...

If I understand correctly, local vs global is actually a scene property in some manner, not just a open/view setting. Thus even if you change the default setting under Project tab > Options > Map and Scene, a scene that has already been created will not change modes: open a project with a global scene when the default is set to Local, and that scene ...

Poisson disc sampling via dart throwing ought to work for an arbitrary surface although so far I've only used it on planes and spheres myself. It's fairly slow though. You generate random points over the surface retaining those which are at least some minimal distance from the others that have been accepted. Stop when you've had some large number of ...

When talking about having only contours in 3D dxf, the proper way is definitely not going through extracting the vertices as XYZ and interpolate surface from points. That way you loose the information about how are the points connected which leads minimally to lose some detail or it can be even critical. If you use Dxf2xyz and you don't want to loose ...

If you export the lines as DXF, you should be able to load them into QGIS. Once they are in QGIS, you need to create an attribute that contains the elevation of each line (ie. a data column with a number). Depending on the total number of lines you could possibly do this manually. If doing it manually is not an option, you could concievably do some Python ...
