Hey, guys i’m trying to generate topo contours from SRTM data using grasshopper’s add on ELK. I use it to generate a simple surface of the topo then when i try to generate contours. I see that some (most) of them are not continuous. I mean when i contour a surface it simply cuts it in the xy plane at certain z heights. So a continuous surface will always end up with continuous contours. But in my case it simply does not ? Can someone please shed some light on this issue. I tried to generate contours from both grasshopper and rhinoceros toolbar but non of them gave proper contours.
