Create 3D grid - topography

[Laure]

Hello ,

 

Sorry for my English ..

How can we create a level like a roof of a sub-layer or a water level .. just a line in my section. Connect different depths between them. DATA allows to assign a text or values to each depth but I just want to connect these depths between her. I don't know if I've been clear…

 

Is it normal that generating a 3D grid (topography) takes several hours ... It's endless. My topography's datasheet contains162000 rows…. my computer crashes all the time… What option should I choose?

 

Thanks...
