Trying to figure out how to fully keep vertical line segments when using Dissolve/unspit lines...
The first image shows the original Zlines in Arcscene
The second image is the result of a Dissolve /Unsplit lines
Vertical Segment (identical x, y but different z) are missing, the vertex are deleted and not simply stacked.
This is a known Problem (already identified with ArcGis10.0 but apparently unsolved) : http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002t00000010000000
Looking for some workaround, I found an earlier Q&A titled Vertical lines in a polygon shapefile. It could be one of the step of a larger process.
Has anyone had to deal with dissolving/unsplitting vertical Segment?
Using ArcGis Advanced 10.2 + full Version of Edit Tools, FME, QGIS (AutoCAD is available, though no expert user on site).
