Getting polylines or polygons out of mulitple arcs

[Ernie.Salazar]

Hello all. I have received a figure from a surveyor who did a photometric conversion from recent overflight aerials. One of the layer was vegetation boundary lines. Instead of using regular lines or polygons they used a bunch of half circles (arcs) next to each other, slightly overlapping, to draw the vegetation lines general shape. Since there are over 40,000 of these little arcs, it really slows things down (they are not even blocked).

Anyone know of a way with either AutoCAD map/LD 2005 or ArcVIew 3.3/8.3 to some how get these into lines/polygons? I do not care if they are arcs, in fact I would rather have them as plane ol' lines. I just need the general shape of the ares they are defining. They will eventually end up in GIS so I can always apply an appropriate line later. I have tried the dissolve features which had some limited success in changing the arcs that are in a straight line into one polyline (with a million vertices's) but nothing that could actually capture the shape of the areas.

Thanks for any help.

You might try using Brake Crossing Objects and then Erase Short Objects from the map cleanup tool. This should give all the arcs matching endpoint. Then you could use the Dissolve Pseudo-Nodes to join them together.

During his drawing cleanup operation he will also
want to convert lines to polylines and convert the
arcs to polylines as well, under object simplification.

Thanks guys! I never used Map clean before. I have seen it but never realized what it could do. It worked well. I have to break it into steps. I had to so Simply Objects by itself after all of the other options for it to look like I want (simple lines). I still have some clean up to do but it will save alot of time with this.

Appreciate all of the help.
