[FAQ264] What is the relationship between Carlson and IntelliCAD?
Starting in 2009, Carlson Software began including a license of IntelliCAD with their desktop software that, previously, only worked on top of AutoCAD. So, now, each user has an option of installing and running these products standalone with IntelliCAD or on top of a separately purchased, full license of AutoCAD.
For more information about the version of IntelliCAD that currently ships with Carlson, refer to this FAQ What versions of AutoCAD & IntelliCAD does Carlson run on top of? And what about AutoCAD LT?.
