Doove Posted June 1, 2009 Share Posted June 1, 2009 Hi all I have a survey drawing in 3D; the contours are 3D polylines. The topo itself is of a square area of a hillside so the countours run through and are not closed. I would appreciate anyone's input on how to use these contours to create a landscape mesh surface or a solid. I'm not having much success with Loft etc. There are also lots of spot height blocks and I remember using a script to create a surface when I trained. Could I export the blocks x,y,z coords to a text file then run a script to create a mesh? The spot heights are not in a regular grid. Anyone done that before?

Mark in Kent Posted May 14, 2017 Share Posted May 14, 2017 I have exactly the same problem. Have you had any luck working out a way to do it? I have been creating a "grid" that uses 2d polylines with 50 or so cross sections - but this isnt perfect and takes ages. Quote Link to comment Share on other sites More sharing options...
BIGAL Posted May 15, 2017 Share Posted May 15, 2017 I have a survey drawing in 3D; the contours are 3D polylines. For me you dont have a 3d drawing you just have plines with z's. There are a few different ways to make 3dfaces interpreting all the vertice points, for me its CIV3D. But as you do not have that search here for Triang*.lsp by YMG which is a triangulation program. "TriangV0.5.9.lsp" you will need to convert your plines to 3d points again search for "Vertices of a pline.lsp" Quote Link to comment Share on other sites More sharing options...
SLW210 Posted May 15, 2017 Share Posted May 15, 2017 There might be something in CadTools that will do it. It's free, but a donation gets some additional functions. Quote Link to comment Share on other sites More sharing options...
