MapWorks is a map import tool running inside AutoCAD, MicroStation, or ProgeSoft IntelliCAD. It processes major file formats produced by ESRI, civil applications and government agencies.
This tool allows you to select multiple files, specify a coordinate window, and quickly import mapping information into your CAD drawing. Also supports grid files from government agencies, along with other application specific formats.
