I have 97 points and 4656 lines contains 3d coordinates and have to do 3D network analysis with them. But now I am facing some problems.
First, I used ArcMap to do network analysis, but no matter where I add a stop, those stops are all "unlocked". Therefore, I cannot continue my work anymore. I doubted that's because they contains Z-cor, so I tried ArcScene to solve, however, as I used the finding route model in tutor, after adding stops I still got error message said "points are unlocked".
Could anyone told me what happened and how to solve my problems? Though I've read tutor I still can't figure out why, so thanks for giving any advice.

The file I have performing in ArcSecne is like below:

It's really a big file and contains lots of lines, so I am even not sure whether it can run network analysis in ArcGIS...

Thanks for any help again.
