Recently I bought some Microstation file for my GIS course project, I want to use the contour lines in arcmap, I export them to Arcmap or even Autocad but all of the contour lines have zero elevation, I don't know how to fix it. Is there any problem with my exporting or there is problem with my source files.
How do I know that my source contour lines have the elevation or not ( I mean Microstation file)?
I upload all of my microstation files which one of them is for contour lines (33G.DGN). I would appreciate your help ;)
This is the link for files :

I've checked your DGN files and it seems that they are not 3D files hence no elevation (z) coordinate is present. There are also no attributes present so I think that using just this DGN file you are out of luck. I would suggest a manual approach on joined contours (one height = one contour). Maybe there is a tool for semi automatic contour elevation attributing using crossing line with start height and end height. Based on contour equdistance height values for all contours can be calculated. I stumble upon such tool several years ago but I don't remember its name.

Thank you so much for your time ,as I don't have enough time to search for that tool, I'm going to do as you suggested (one height= one contour) :)
Thank you again, Lui ;)
