Can you just move them all in the z-axis? Select move, highlight them all and type @0,0,-366 <enter> This will lower everything by 366'. Sorry if I misunderstood your dilemma. I don't know your skill level.

Create a block from the 3d polyline, reduce it in the scaleZ block by 10 times, break the block and get the desired result

You probably won't be able to use SCALE for this. But you can process the individual vertices. Use the ModDXF utility and process the DXF group 10 (vertex), multiplying it with the vector:
1,1,0.1
