Wall Breaklines

[Anonymous]

I am having a problem with my Surface not cutting to the exact Wall Breaklines that I have drawn..The problem areas are the vertical wall to the north in the drawing. Specifically the vertical 90 corners. I have attached my file. Thank you.

Are they supposed to be squared like this?

Yes, exactley except hard to tell if the top of the wall is sloping in elevation but yes that's how i wish it to look like..

I think you may be misinterperting what Alan said. With the Delauny trinagulation algorithm you WILL have a problem with common xy different z

I could be. I will recut the surface using no upper lines, like I have done for the walls running North/South and retry..

I have tried removing the upper lines and it worked almost brilliantly see attached. I have only one small area to fix. See attached.

OK. Despite what I said before. I had to look at it more closely. actualy looking at it from the underside let me see what was happening better.

I moved the bottom of wall away by 0.01 and flattend the peaked breakline i showed in the other screenshot by picking the Mid between 2 Points using the adjacen verticies. One difference between the one that worked for you is that it was create with a flat polyline. The others were created as segments of 3D polylines.

That's how I thought it was suppose to be Allen. Note that there are a number of surf warnings and errors. Mapclean does find some duplicate objects which also does not fly well with the algorithms.

There is also points and a line defined as a drawing objects This also adds to the errors. If the line lies on all of the points remove the line. This is data redundancy.

For some reason, I clicked on the surface and swaped the line that was crazy and it seems to have worked. I didn't notice the difference in Polylines. Thank you very much for your help, Allen. 🙂
