FAQ: Why are elevations values not maintained when converting a 2D shapefile to a CAD drawing?

Question

Why are elevations values not maintained when converting a 2D shapefile to a CAD drawing?

Answer

Attempting to convert a 2D shapefile with just elevation values requires maintaining the elevation values of the 2D shapefile. It must be converted to a 3D feature (PolyLineZ), then to a CAD drawing. The elevation values must be stored in the geometry as in a 3D feature, rather than the attribute table as in a 2D feature.

Note:
3D Analyst is required for the conversion process.
