Even with a lot of 3d work - NOT all and I'd say 70% of my production set is not 3d Models but 2 d stuff.
The Connect version has 3d Detailing TOOLS but took away much of the 2d Detailing tools. Wall Sections, Buiding Sections, Revisions, etc.
I need those badly. I have to go back in SS6 to finish my work and with the issues of that causing corrupt files I need this in my Connect workflow.
It is a game stopper.
