How does ArcGIS read elevations from 3D AutoCAD polylines?

Last Published: April 25, 2020


ArcGIS will read and display the elevation values for all supported entities, which includes 3D polylines. In situations where all of the vertices of a polyline feature do not share the same Z coordinate values, ArcGIS will take the first vertex it encounters and use that Z value for all vertices that form the polyline. The order of vertices is determined by the to-from direction of the line.
