nadi OFFLINE Junior Boarder Posts: 37	Hello to all I get an error when I want to generat a mesh. Could it be because of my topographic coordinate system? What solution do you suggest? Thank you for your help before regard Attachments: errorinT3M...erat.png (165KB)

Hi Nadi,

It looks like you are using LatLong coordinates for geometry and you specify 800 as the default edgeLength.
You have to work in a consistent coordinate system.
If you want to work in LatLong, then edgeLength must also be in degrees.

In general it is best to work in a cartesian coordinate system like UTM and specify edge lengths as metres and then convert the mesh to LatLong afterwards.

Hope this helps... Martin
