Good Morning! Yeah, I could probably get by on SketchUp 2017, I think that is when dashed lines came into play. Otherwise there is nothing new or interesting… I guess LayOut has made a few strides too. Either way you are now pinned down into a $299 subscription for SketchUp. Good news is you will always be on the latest and greatest version!
I would recommend following all of the links on the Learn page, they will take you where you need to be. Don’t overlook the Knowledge Base, I have been writing a bunch of articles lately…
Thanks for your support! Let me know if that helps…
