Generate DTM from scanned tunnel, is there any way to do this with Bentley software

The MicroStation Mesh from Points tool has a tunnel option.

Hi Ron

Mesh from points means that you have to write your scanned laser points to dgn file, you can not use .pod files with this function.

I tried to use Mesh from points tool but had problems to snap to the center of tunnel and even that the tunnel was in a curve did not make the direction as shown in the example that easy, so no, not exactly 100% but the idea is good. I rather see that you could select the tunnel xml alignment line to force the triangulation to do exactly as in the example, but then Bentley needs to first add an land xml alignment import function first.
