# Network
## 
Network
The NetworkSrf command creates a surface from a network of crossing curves.
* All curves in one direction must cross all curves in the other direction and cannot cross each other.
* The command always smooths out the output surfaces even if the input curves have kinks.
### Steps
* Pick the curves in two directions that form a network.
Or, use [Windows-selection](https://docs.mcneel.com/rhino/8/help/en-us/commands/selwindow.htm).
