Hey everyone,

I'm working on a big project in MoI (a train station + the surroundings)

I already made the building from scratch (based on floor plans and cutaways)

As you can see in that screenshot it's really big...

I received the 3D topography data + buildings around the train station area in DXF

I can export the buildings but I need to make a 3D terrain from the topography curves

Here's a screenshot

And here's a screenshot of the 2D file I got for the streets

Could anyone tell me how to do a terrain from splines ? Here's the file in DXF if you want to play :)

Thanks a lot for your help :)
