A conical frustum is a cone with a flat surface top, or without a pointed end. It can depict the shape of a mountain and can be used for general measurements, such as the surface area of a mountain top. A conical frustum can be created in ArcGIS Pro by creating two multipatch features; a cone and a cuboid. The two features intersect in a way such that the cone is cut off from the top and the final result returns a conical frustum.
The following procedure describes how to create a 3D conical frustum in ArcGIS Pro.
Note: Ensure this procedure is performed in a Scene layer. Both the Local and Global view can be selected from the View pane in ArcGIS Pro.
Note: The cuboid feature must be wider but shorter than the cone feature so that the entirety of the bottom part of the cone is preserved when the two features are processed. The image below demonstrates the multipatch features prior to creating the frustum.
