The Chain Extrude tool is in the Building Shell tool set.
The Chain Extrude tool automatically creates extruded objects with both continuous and repetitive elements. Architectural features such as an awning contain a continuous element (the awning) and intermittently repetitive elements (the supports). By specifying the polygon or polylines to be extruded, and then indicating the path of the extrusion, the object(s) are automatically extruded along the path.
