I was looking though some old marketing materials and found a video of an ArcView project we did back in 1999-2000. I’m laughing as I look at it, partly because we’ve come such a long way and partly because I remember all the hacks we had to perform (making those tabs appear was an amazing pain in the ass). I showed it to the primary Avenue programmer and he just wanted to walk out the door. I’m guessing he didn’t want to remember the pain that project caused him. If you look at the toolbar, you’ll see a little “zipper icon” that people named the zipper tool. If I remember correctly it took the area out of the polygons and updated the area field in the back end database. We always had to remind people to “run the zipper tool” after updating any layers. Ah those were the days.
