Hi all, I am converting a 2d topographical survey to 3d, most of the lines have been processed into 3d and are now 3d polylines, what I have to do is go round the drawing filling the gaps. The problem I'm having is although I know 2d polylines are easily edited and joind to other polylines or lines, I cannot work out how to do this with 3d polylines. I am using Autocad r14 and would like to know how to do this if its possible, if not, is there a way of doing it in autocad 2005? if so i can use my cousins version of 2005 to do it. What I don't want to have to do is create the 3d polys from scratch and trace over the survey drawing, this will take ages as the drawing is pretty big. Thanks in advance for any help given, it is much apreciated. Shiva
