Over the last dozen or so years I have created 7,100 models in Sketchup Make. As you may have guessed the vast majority are rather simple... variations on length and width for the most part, but also many very complex models such as large steam era passenger train stations -- for example http://www.elvastower.com/forums/index.php?app=core&module=attach§ion=attach&attach_rel_module=post&attach_id=93302. I've never had any need for SU Pro and there is no way I would entrust so many models to Trimble's cloud storage.
Which is to say I'm using SU 2016 and have no need / intention of using anything new from Trimble.
My question for the future is this: What happens when I have to build a new PC? Maybe this year, certainly before the end of the 2020. I have the installer from 2016... will it install and produce a working copy of SU Make or is this licensing stuff Trimble is talking about right now going to prevent that?
