This is my first post to this newsgroup, so please forgive me if this topic has been discussed before.
I have a drainage area map that I have created with plines in AutoCAD
2005 Map (which includes the Land Development package). The drainage areas are not closed polygons, however. Some of the lines cross, some do not close, etc.So, I figured out how to do a "clean up" of the drainge area map to produce individual line segments and nodes. Now I need to create separate polygons of each drainage area so I can get the area of each one. I have over 200 separate areas, so the procedure needs to be automated to do the whole map at once.
I tried the "create polygons" procedure in Map, but with no success. I keep getting error messages. Does anyone have a link to the exact, step-by-step procedure on how to do this, or any tips on what I might be doing wrong?
After all the closed polygons are created, I can use the "Parcel" command or "area" command to query the polygons for their areas.
Thanks so much for your help.
