What is the best addition to AUTOCAD 2017?

thanks for invite

i have't used 2017 yet 

thanks for the invitation

InnerSoft CAD is a plug-in for AutoCAD that installs a set of productivity tools for Civil and Survey engineering, Counting, Estimating and measurements in construction project budgets.

The mostly used addition of auto cad is 2006 in our country.

I've checked autodesk.com to see the new features in AutoCAD 2017. I think the best addition is the coordination model in which you can model from an inserted Navisworks file into AutoCAD. I still haven't used this feature but for me it is the best addition.

In my opinion , [Multiple Offset ] addition created by /Engiware
