Hi everyone!

I am currently modeling landscape using the Sandbox extension.  
I imported the contours from a cad drawing and gave each contour the correct height.  
Clicked “create sandbox from contours” and most of the terrain was fine, but a section was very odd. Since my contours go around an existing wall in the landscape the rendering doesn’t contour it but just triangulates over it.

Is there any way of correcting this?

Cheers,

Joao
