Willie, who wrote the software ?
I thought this was interesting ..

It is indeed interesting Kerry. I have a fresh install of Acad / Civil 3D 2008 and decided to see exactly what happens when this is installed. I found an amazing thing virtually unheard of for AutoCAD add ons lately. Installing this package does absolutely nothing to my AutoCAD install - no trace of any extra menu, toolbar, or even a search path addition. It is a stand alone program that right now has a menu with toolbar running on my desktop with no AutoCAD running at all. It has an option for r2000-r2007 support or r2008 support that can be selected and changed at will. It is apparently crippled to some extent with the free download but promises to provide a registration code for full functions with any size donation.
As for the tools themselves, a number of them seem to be duplicates of functions within the civil verticals or even in expresstools but the package seems very promising for someone without access to those vertical products. There also appears to be functions that transfer data to Excell and I think there may be a few functions in the registered version not yet available for Civil 3D or Land Desktop.
Thank you Willie for sharing this . . . it looks like a very promising find.
