Extracting point data from contours?

[Anonymous]

I am trying to create a surface by adding contour lines from a layer (LIDAR countours), but I get an error that all of the breaklines crossed a point.  The point(s) appear to be uniform edges (ie: boundary?) along the top and bottom of the contours. 

     - I have tried allowing this in the definitions to no avail.

     - I don't have the original points file.

As a solution, would extracting the points from the contours and creating a new surface from the points work?  If so, how do I extract the points?

Thanks

do you get a surface? That is usually a non fatal event. and youll see it often

No.  It gives errors on all of them and does not create a surface. 

Thanks

MAYBE IF YOU ADD FILE THE HELP MAY BE EASIER. HELP YOU BETTER UNDERSTAND THE ISSUE

Here are the error messages:

Adding a drawing will help us here a great deal. We need to see what the data is and how your trying to consume it more than anything. It should garnish a quicker response as well

Every one of those crossing breakline messages is pointing to the same location. Have you looked at that spot to see what is happening there?

Are you creating a surface or adding data to an existing surface? Your image shows the surface LIDAR has one or more edits as well as contours added, what are the edits? Make sure the surface has a style that displays and has been rebuilt. As others have said, there are so many variables and possibilities, we need to examine the drawing file to determine what the issue might be.

What type of entity are the contours?

[ChicagoLooper · Accepted solution]

The error you describe suggests the contours were not generated properly. Re-create the contours then make your surface. Using the same faulty contours will not change your results.

As a work flow, this if odd. You started with 'points' and someone, maybe you, maybe not you, proceeded to make contours. Then the contours were used to make a surface. Why not skip the contours and go from directly points to surface? I realize you don't have the original file and going back to LiDAR may not be an option, but repeatedly using those contours and expecting different results is unrealistic.

The faulty points appear to be along the edge of the data, as I said initially.  Someone else provided the contours. 

I'm going to find some original LIDAR points and start over.

Thanks for the help guys!

Wait a minute? Why are you adding contour to Lidar data? something sounds off Or I missed the boat

create points , contour vertices
