TextToFeature folder.
Making Polygons from Lines
Now that you have created a line feature class, you are able to make polygons from it. The process is a
little convoluted and certainly deserves a line or two in your Fast Facts File.
12. Restart ArcCatalog (not just the Catalog Tree in ArcMap but the entire program). Open
ArcToolbox. Expand the following: Data Management Tools > Features, and then pounce on
Feature to Polygon. Peruse the Help. For the Input Features text box, using the browse icon,
navigate to the TextToFeature_Lines feature class entry and click it so it appears in the Input
Features text area. Change the name of the Output feature class to TextToFeature_Polygons in
the path
___IGIS-Arc_ YourInitials \TextToFeature
Click OK. (You may get a rude shock in the form of an admonition. If so, close ArcMap and
try again. If not, just proceed with the next step. See the discussion immediately below to
understand why ArcGIS sometimes refuses perfectly reasonable requests.)
