land1 Posted September 12, 2007 Share Posted September 12, 2007 I am trying to create a small site model using polyline contours as base information. I have followed the instructions to the letter (I think)but have no result. I have converted the polylinnes to polygons - in the aec pull down selected survey input>2d polys to 3d contours.- set a start elevation and interval (500mm for the small site). Now when the set elevation box comes up no contours are highlighted and the process comes to a halt. What am I missing - I have successfully created site models before in this manner.

Pat Stanford Posted September 12, 2007 Share Posted September 12, 2007 I think the problem is that there are object on the layer other than the polygons. Try copying the polygons to a new blank layer, set the Layer Options to Active Only, and try it from there. If you have to cancel in the middle, it will still create a partial object, which will mess you up the next time, so delete all and paste the polygons again. Pat Quote Link to comment
land1 Posted September 12, 2007 Author Share Posted September 12, 2007 Thanks for that, I will have a play today. I have created the polygons on a seperate class and turned everything else off for selection. Creating these on a seperate layer would be better - less chance of the above situation occurring.

islandmon Posted September 14, 2007 Share Posted September 14, 2007 Try creating your DTM in a separate clean file . then use WGR . This simple process avoids all manner of problems and possible file corruption from failed conversions. Quote Link to comment
