I created a surface with a boundary. At a couple locations near the boundary line, there are areas where there are no tin lines. I keep trying to add lines in order to fill in these areas but the software will not allow me to draw the lines. Would anyone be able to think of any reasons why this might be?
I tried moving the boundary outward, and at one of the locations the TIN lines came in after rebuilding the surface. The same cannot be said for the other locations, however.
Any ideas would be appreciated.
Thanks very much
I believe you need to use non-destructive breaklines when creating the boundary.
Specifies whether or not to create boundaries with non-destructive breaklines. This clips the triangle edges exactly where they cross the boundary.
can you post the surface, or at least a small portion of the surface where the problem exists?
someone may be able to find a solution.
I've had similar issues and always seemed to be able to get the tin lines to show eventually.
One of the first things to check when you have boundary issues is to make sure that they are modeled in the correct order. A single outer boudary would typically be the last operation on a surface. If you are unsure about the operation order of your boundary, open the surface's properties dialog. Go to the definition tab and look for your boundary operation in the operations list. If it is not last select it and use the arrow buttons to the left to move it down. Rebuild and see if the boundary is processed correctly.
