I am attempting to create a new polygon. I go to ArcCatolog>New>Shapefile and make sure Feature type is set to polygon. I create the polygon and if I click save edits or stop editing, it disappears. What am I doing wrong?

You need to finish the polygon's construction with double click, right-click>Finish Sketch or F2 before saving edits.

Thanks, I tried that and it worked perfectly. Appreciated – Tim Forssman Aug 19 '14 at 14:49
Once I have double clicked and saved it, can I come back and continue adding points to the polygon to extend it? – Tim Forssman Aug 19 '14 at 14:50
Yes you can. Keep update session open, then use this tool :… – egoz Aug 19 '14 at 14:54
@Tim Please consider accepting egoz's answer if you feel it was a good solution. – Aaron Aug 19 '14 at 19:32
Further to egoz, you can use the Edit Vertices" and continue feature tool (the little pencil and line) to continue drawing a line/extend the polygon – GISKid Aug 19 '14 at 20:19
