PRISM, Z1, Z2
Creates a prism volume based on working plane coordinate pairs.
Defines a prism volume based on the working plane. The top and bottom areas will each be defined with NPT keypoints and NPT lines, where NPT (must be at least 3) is the number of coordinate pairs defined with PTXY command. Also, a line will be defined between each point pair on the top and bottom face. See the RPRISM and RPR4 commands for other ways to create prisms.
