Not easy in anything but civil software.
With the software I have I would use a script to import the points into
AutoCAD.
Import the 3D point cloud into Viz. Make a mesh of this.
Slice the mesh at my contour intervals. Export the generated plines as
AutoCAD DWG.
Import the DWG into AutoCAD and Revit will make my topo from that.
I think I could make a journal file that would create the topo surface, but
wouldn't be a simple thing.... Have to give it some thought.
