But how does arcpro distinguish multipatch from polygons. It is available on the context menu when you create or split polyline or polygon features. It can have attributes and be used with the standard tools, such as the identify tool.
Resulting multipatch will capture the 3d surface representation in its geometry. Open the arccatalog window, and navigate to the geodatabase that contains the point, polyline polygon and multipatch features from the cad file.

See tool help at multipatch footprint arcgis desktop help. Both of my feature classes the polygon and the multipatch are in the same coordinate system, nad 83 pa state plane us feet navd88 us feet, but 2 distinct differences are that 1 the bottom of the multipatch shapes are at a constant elevation rather than on the ground like they are in the polygon. Splitting can improve the regularization of the resulting building. The output footprint will have the same fields as the input feature, along with the following fields.
