The last post we set up the surface and indicated a problem with the mid-ordinate distance when adding breaklines to the surface. In this post I'll investigate the problem further. First I'll re-add the breaklines to the surface with a smaller mid-ordinate distance.
We can see from the picture below that with the smaller mid-ordinate distance the contour follows the curb better, but also causes problems in the surface with the contours not exactly being where they need to be.
A larger view of the surface showing the problem.
To clean up the surface I'm going to create a corner to catch all of the smaller triangles around the curb radius. This will prevent the triangles from going place we don't want them to go.
We can see TIN surface collecting all of the TIN Triangles from the radius curve.
In the next post I'll modify part of the surface to remove one of the two low points.
