Have someone idea how can I do this?
The idea is similar to this from 2012, I want to build a surface from polylines references on the section views. I need to recreate a surface from this CAD informations

Hi @Eduardo.Soethe,
Here’s an example for you to try. Does it get you close?

Omg… I’ve tried to do this before and couldn’t get it working 
I’m definitely going to use this. Thanks Zachri!
To be honest, I haven’t encountered a situation yet where this would be necessary. If I needed to reverse-engineer a surface from a set of plans, I’d probably use the alignment, profile, and typical section to build a corridor (assuming it was provided). Can anyone share an example use case?
When I was trying to do this, my intent was to create a complex datum surface for the purpose of roadway quantity and earthwork calculations. I had highly variable sections that seemed difficult to model as a corridor. Although my skills with corridors is highly limited so perhaps that is why this script is highly useful to me.

It’s a good option to create geological surfaces from sections.
