I have never really had good luck building a dtm surface from existing contours I receive as polylines. I know it's not the most accurate way to build an existing surface, but when that's all you have...I'm sure you know what I mean.
I always seem to get a lot of triangulation that cuts contours off, and the contours of my new surface are only about half way close. For the work I'm doing, it's probably close enough, but I would like to improve it.
It takes forever to swap edges and modify the triangulation to make the contours more exact, is there a quicker and easier way to get a better result from contour lines?
Again, I know this is not the best way to build a surface (too bad the drawing didn't even come with the tin triangulation!), but I have to work with what I have.
Thanks for any advice in advance.
