I get the 20,2 error when creating a model from imported autocad lines. I first converted them to 3d polys, applied the correct heights ("Z"-values) and then tried to create a site using the DTM. I also tried to simplify the polys or to convert them to 3d loci. In both cases I still get the 20,2 error.
Now I tried to clean the polys: How can I locate the intersection points? To what do the coordinates given by the check-command refer? Looking up the location with the X- and Y-coordinate on the upper left side of the window... I find a sector of the file where there is nothing... empty!!
Anyway: When converting the polys to loci I shouldn't go on getting the 20,2 message (because there are no intersections anymore, are there?), but it still appears... WHAT CAN I DO?
Info: I have 558 polys which become 2283 loci when converted.
