    Default calculate the total length of a group of polylines

    I have a project where I have numerous polylines that I need the total length of. They are AutoCad polylines at the moment. What would be the process to have a total distance for all polylines on a certain layer to be displayed somewhere on the drawing. I have very little experience using the GIS functions of Map3D. I am working with 2008Map3D. Any guidance would be appreciated. Without the prior GIS experience the terminology in the help files I have looked at has made it somewhat confusing trying to figure out the processes needed.

    I can't help you with the features in Map (if there are any that will do this), but in the meantime, you can download TLEN.LSP from http://www.turvill.com/t2/free_stuff/ and use it.

    On the map side of it you would need to create a topology of those layers, however that only works with the autocad objects. Using data connect and FDO there is no easy method at this time for it that I know of. The tlen.lsp that R.K. posted about is your best option IMHO.

    Create the topology, then right click it in mapwspace and choose statistics.
