I've got an interesting problem I keep running into; so far the only way I've been able to resolve it is by hours of brute force, and I'd like to see if there are any other options.
I often work with large "historical" contour data that comes from literally who knows where. I say "historical" because I am not able to contact the original creator/company of these contours. This contour data has all been saved in DWG format (not SHP) and appears always as a bunch of lines, not referencing some 3D imported object/source. Clearly all of the contours are marked and separated out into their own layers, but there is never any elevation data, meaning all of the contours are at 0 elevation. I'm currently solving this by clicking on each line and updating its elevation field, which takes hours for each file. Is there a smarter way that Map 3D can recognize these lines as contours and make injecting elevation data easier?
