The Sweep tool may be what you are looking for. If you just need to sweep a 2D profile along a path, the Sweep tool will do it. The Sweep tool will work on a polylines such as those in your submittal.
In my Turbocad Manual, the Bend To Path tool is described as capable of working with polylines. When activating the tool, the prompt at the bottom of the screen asks for a line, arc, or spline. I tried these entities and they work. On my system, polylines, like yours will not work with the Bend Along Path tool.
