How to convert overlapping polylines to overlapping polygons

RickBombaci — Thu, 13 Nov 2014 01:01:41 GMT

I have a shapefile with overlapping "polygons" that are actually polylines. How can I convert the polylines to polygons without having ArcGIS converting the areas of overlap into new polygons?

For example, if I have two overlapping polyline figures, I want to end up with two overlapping polygons, not three (where the third polygon is actually an area of overlap between the two polyline figures).

Thank you,

Rick

there has to be a quicker way than saving each polygon as a separate file, then merging them together...but in a pinch it would work

I have never tried ET_GeoWizards tools. There are several free tools in the toolbar and Polyline to Polygon looks to be one of them. It may be worth a shot.

Another option more along the lines of Dan's response would be to create a model that iterates over a unique value in your polyline layer which then converts each polyline into a polygon. Each polygon would be in it's own feature class and then you could merge them together.

Thanks to Dan and Steven for your suggestions. I noodled around and found an excellent tool from Jenness Enterprises called Tools for Graphics and Shapes (Jenness Enterprises - ArcGIS Tools ). Simple to use, and did exactly what I needed with no fuss or bother.
