One of the Visual3D segment geometries is labeled a **Cone.** To be precise the **Cone** refers to a **conical frustrum.** A **frustra of right cones** is created by cutting the top off of a cone such that the cut is parallel to the base of the cone. | One of the Visual3D segment geometries is labeled a **Cone.** To be precise the **Cone** refers to a **conical frustrum.** A **frustra of right cones** is created by cutting the top off of a cone such that the cut is parallel to the base of the cone. | ||
