Filter 3dpolylines/breaklines

[troyhill]

Can you filter 3dpolylines to find which ones have a vertex at 0 elevation? I do not see the option in the Object Selection Filters dialog. We have several 3dpolys which would take a while to go through each vertex.

I just use 3dOrbit to get a 3d view and easily find the errant objects.

Or if you're adding them to a surface anyway, just go ahead. Then look at your contours, they should tell the story.
(Caveat: if your linework is close to zero anyway, neither idea will work. So sea-shore topos need a different idea.)

I didn't even check it because I thought the OP said they checked there, but I misread that post I think.

I usually just use a 3d view but was just seeing if there was a method through the Object Selection filter since it was a large topo.

The surface method of lookin at errant contours wasnt an option because the computer was not allowing a surface to be generated.

I dont know why I didnt check quick select. That is the quickest method, as you can find all errors at once.

Thanks for the responses.
