Carlson Software recently released version 2019 of its product suite including Carlson Mining, Carlson Survey, and Carlson Civil/Hydrology/GIS. Carlson products come with IntelliCAD built-in and an option for their end-users to purchase Autodesk® AutoCAD® separately if desired.
As expected, new features are found throughout the Carlson product line. Special mention goes to working natively with both .dwg and .dgn files. Open, save, print, and edit all with one CAD editor thanks to the IntelliCAD 9.0 engine.
