ArcView 3.x Extensions
These extensions should work in any version of ArcView 3.x (3.1, 3.2, or 3.3). All can be installed by copying them into ArcViews EXT32 extensions directory (C:\ESRI\AV_GIS30\ARCVIEW\EXT32\ or something similar), and are turned on by placing a check in front of their name in the File/Extensions& dialog accessed though the ArcView menu. If you would like any of them to be always on in all of your ArcView projects then place them in the Tools subdirectory (C:\ESRI\AV_GIS30\ARCVIEW\Tools\ or something similar).
