I've really started to like Sketchup for simple work after buying Dave Richards' Tutorial.
I was fairly happy with v8 but the lack of 3d Warehouse working with that caused me to upgrade to 2013.
Sketchup 2013 was compatible for creating Symbols in Chief Architect x6. Symbols is their word for items like furniture, cabinets, windows, doors, lighting, etc.
I'm just setting up a new Workstation for my own use and went ahead and installed Sketchup 2016. CA x6 doesn't import those and saving in 2013 format is a pain because as you save your work it saves in 2016 format and then you have to remember to save a final one to use for CA.
I haven't yet seen much difference so am considering just installing Sketchup 2013 for everything. What am I losing?
Sketchup is a pain with older versions as it tries to get me to update every time I open it. Almost as bad as Microsoft trying to get me to downgrade to Windows 10.
