 Topic: Scale polyline ZPosted: 21.May.2025 at 14:56 |

I have a DWG file with 3D polylines containing Z-coordinates with exaggerated elevation, Z is 10x higher than it should be. Is it possible to scale those polylines 10x smaller, but just in Z?

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 similarly to the tip https://www.cadforum.cz/en/how-to-move-vertices-of-a-multiline-in-z-axis-tip14539

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

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.
