![]() ![]() Spline curves take up a huge amount of drawing space and lose accuracy on sharp contour corners if not enough points are supplied. Option 2 draws plines thru each triangle surface on temporary layers, then selects all lines on each elevation, joins them and asks if you want to create spline fit curves. If you need to change a space separated point file to a comma separated file, try one of these command line programs.ģ2 bit version s2csv32.exe or 16 bit version sp_2csv.exe. (8 character file names only.) If you don't have any points, check out these DEM Point Selection programs. Don't use any more points than the resolution you need. More points don't necessarily create a better contour map but will only increase the dwg size. The check option will delete any duplicate points and draw a circle on layer "CTL_PTMP" around the points closer than allowed. If too many of your points are closer than 1 unit and you can't move or delete them, you'll have to scale all of the points up to create the surface and then scale it back down to the original scale. If any points are closer than 1.0 unit apart or there are duplicate points in the drawing, the program will hang. It prompts to check points before the surface program runs. Option 1 creates a triangulated surface from all points found on layer "CTL_PNT". Type "CTL" at the command prompt for option list. Type (load"ctl_w8") at the command prompt to load routine.
