2016 is unfinished (see post above) but if you watch the video on Extragroup's website the potential for quick, dynamic editing is pretty impressive.
I am using 2014 until the panel door creation section is completed, which is supposed to be soon.
I like 2014 a lot but one can't install interiorcad 2014 and run it w/ VW 2016 which is really unfortunate.
I'm told that when VW went from 32 bit to 64 bit in 2015 Extragroup had to completely rewrite the program for the new Architecture.
Being a woodworker, I don't understand the previous sentence that I just wrote but it does seem plausible.
I really have high hopes. I'll let you know in a couple of months how 2016 is.
