Currently I am working on the extraction of building footprints using ArcGIS/ArcPy and Lastools. Using LasBoundary I extract all buildings from the lidar dataset and get the building outlines as 3D polygons (Polygon ZM). In order to improve/enhance the geometry of the outlines I perform a smoothing by means of "Regularize Building Footprint" as a subsequent step.

Unfortunately I only get 2D-polygons as result. Is there a possibility to keep the 3D information or to add it again?
