mhinks Posted June 22, 2004 Share Posted June 22, 2004 Hi Hope someone has come across this problem before, and can help me out. Ive got a land survey generated surface in max and am trying to get the surrounding landscape imported from a DTM/DSM format. I've got an ASCII txt file of x, y, and z points, but cant get that in either. Ive been send 3d dxf files with thousands of points but no surface! They seem stuck at there end, is anyone here in the know!? Thanks Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted June 22, 2004 Share Posted June 22, 2004 What other formats can you export to? Link to comment Share on other sites More sharing options...
mhinks Posted June 22, 2004 Author Share Posted June 22, 2004 Im not sure what other formats can be generated. Its another company that is providing the data, and they are being rather slow in getting back to me! Link to comment Share on other sites More sharing options...
3danim8d Posted June 23, 2004 Share Posted June 23, 2004 Mhinks, Do you know what program they are using to generate the point data? I have taken point and breakline data from a Microstation/Inroads DTM and created a DXF surface by exporting the triangulated data to an AutoCAD R14 DWG file from Microstation. Your contact should be able to do something similar. I was then able to bring this into 3D Studio Max and using autoweld to turn the 500,000 some odd individual triangles into one surface. It worked great, but it took like 8 hours for the autoweld process on my Dual P3-1 Gigahertz with 2 gig of ram. Once that was done I added the aerial photo as a texture and it looked great. Does anyone know of a script that can turn the ASCII points into a surface? You could also try MicroDEM. Load in the points and then output a surface, I don't remember what it outputs at the moment and it's not installed on this machine. Good luck Link to comment Share on other sites More sharing options...
mhinks Posted June 23, 2004 Author Share Posted June 23, 2004 Thanks very much for your info 3danim8d, Im trying to get hold of them now to ask. Im also getting in touch with the OS how have the UK mapped as high res contour data, with matching aerial photos. I can then use the new terrain compound object in max 6 to surface the contour strings. Fingers crossed Link to comment Share on other sites More sharing options...
Vince Paske Posted June 25, 2004 Share Posted June 25, 2004 I've had success using EasySite to import ASCII files directly into AutoCad. Once all the points are brought in, you can form your "tin" with options to control the mesh size. http://www.cadeasy.com Cheers! Link to comment Share on other sites More sharing options...
