About...
This extension is the result of a cooperative project between the
Norcross Wildlife Foundation
(Wales, MA) and the
Massachusetts Department of Environmental Management
(Boston, MA). DEM is now called Department of Conservation and Recreation (DCR) Division of State Forests and Recreation.
If you find any bugs or errors in the extension, or have any comments, please forward them to
David Kimball [davidfkimball@hotmail.com]
or
Nathanael Lloyd [nathanael.lloyd@state.ma.us].
Please include an exact description of any error messages encountered and what you were doing when they occurred, as well as what version and date of the extension (you can find this out by clicking on the extension’s name in the list of extensions under ), what hardware platform (Windows NT4.0, 2000, XP, 98, UNIX...), and what version of ArcView (3.0a, 3.1, 3.2, 3.3, etc.) you were using. The extension was initially developed on a Windows NT 4.0 machine running ArcView version 3.1. The extension has been tested extensively on this platform and on version 3.2a on a Windows 2000 machine, and minimally tested using version 3.0a on a Windows 95 machine, version 3.1 on a Unix platform, version 3.2 on an NT 4.0 machine, and version 3.3 on an XP Professional machine.
We may be unable to answer every ‘how do I do this...’ type of question due to time constraints, but we will try to respond to bugs you may find. Suggestions, of course, are always appreciated.

Version information
You can tell what version of the extension you have by choosing from the menu and clicking on the name of this extension. The version and date information will be displayed in the box at the bottom of the Extensions dialog.
1.3
- The current version is 1.3
- Released January 2005
- The node drawing environment was re-coded to improve performance. This means that when you are editing a line shapefile and are in regular Select mode, the red and cyan dots that mark dangles and pseudonodes, as well as the colored selected lines, will draw much faster than in previous versions.
- The QuickSnap tool (which has been available separately on ESRI's ArcScripts page for a while) is now integrated into the Parcel Editing dialog. It is used for snapping line endpoints together quickly, easily, and accurately. It now has three different modes.
- A new button has been added to the Parcel Editing dialog that removes every other vertex (but not endpoints) from the selected lines. This is useful for when your lines' vertices are too densely placed.
- The code for the Mark Intersections button has been modified slightly to improve performance. You should now be able to test a few hundred lines in a reasonable amount of time.
- The Grabber tool has been updated; it will now grab every part of a multipart line or polygon (including donut polygons) and make each part into a new feature. Previously it would only grab the first part of a multipart feature or donut polygon.
- A few other minor changes were made.
1.2
- Released September 2001
- The previous version had a bug where projections involving UTM zone 18/19 gave bad coordinates (off by a few hundred meters). This affected the following options: Add Points from X,Y Coordinates; Write X,Y Coordinates to Theme Table; Add New Point tool (Attribute Editor). Avenue does not make projections easy to work with! These projection options were only set up for use in Massachusetts so users from other areas and anyone who was not using the extension to project UTM coordinates should not have been affected. This problem was fixed by borrowing some code from the MassGIS Dataviewer's GetPoint script. Thanks to MassGIS' Aleda Freeman!
- Clicking the Help buttons gave the wrong internet URL for this help document in a pop-up message box. This was fixed in this version.
- A few other minor changes were made.
1.1
- The first publicly available version was 1.1
- Released December 2000
- The vast majority of the extension was written between September 1998 and February 1999. Revisions were occasionially made between then and the release.
