Color-Coded Elevation Triangles


Hi, I am going to ask a question about Color-Coded Elevation Triangles.

 

1 I create a DTM with triangulation (Max Length 1.50m). The triangles are fine. 

 

2 Generate the Color-Coded Elevation Triangles, and I applied Fence Mode, the colored triangles are weird:

Anyone has ideas about how to make the color triangle correct?

 

Thanks...
