Richie Hatch Posted April 1, 2001 Share Posted April 1, 2001 I'm trying to use the digital terrain modeling tool. i have drawn the contours as 2D polygons and used the 2D contours to 3D poly tool. When I then go to New DTM tool and click along, i get an error code 4,5 message? what does this mean? richie Quote Link to comment
Marc Pitman Posted April 1, 2001 Share Posted April 1, 2001 A few things you may want to check: Did your 3-d polys all have the correct z value after running 2-d contours to 3-d polys? Check by selecting 3-d polys and looking at the z value in the info palette. Also check to see if the range of z values match the range shown in the settings dialog box. If not you may need to change the scale of your 2d poly layer to more closely match the map you are tracing the contours from. Do any of your 2-d contours cross? Run the DTM/check 3-d polys menu command to make sure. Are some of the 3-d polys too close together? Run the filter 3d polygons tool to check. These are a few things I check if a DTM does not work.
