The Natural Regrade module
with GeoFluv™ is a module of the Carlson Civil / Survey family. As
such, it functions in tandem with the widely-used
AutoCAD drafting software. Carlson Civil / Survey is application
software
for the civil engineering, surveying, mine engineering, and GIS
disciplines that use AutoCAD as the graphics engine and drawing
editor. Carlson Civil / Survey's system requirements are no greater
than
that of the AutoCAD version with which it operates and will work with
any AutoCAD-based product from AutoCAD 2000 through AutoCAD 2007.
