I installed the free 2017 standalone version of Sketchup, but don't use it much. It will run on your home computer without the internet, which is what I wanted. In general, I prefer standalone, locally run copies of the software I use. Here are a few lessons I learned from the free standalone 2017 version of Sketchup:
* The 2017 standalone version is not easy to find for downloads. I just looked, and it appears that you must create an account just to see the download links. I do NOT recommend download copies from any source other than the official Sketchup website. Other copies may contain adware or malware or worse. (When I downloaded it, I did not have to create an account.)
* The 2017 standalone version still tries very hard to get you to use the online version. Every time you start it up, the default is the online version.
* The 2017 standalone version starts out as a full version. You must wait 30 days until the trial period expires, then it automatically reverts to the free version, which lacks some of the "pro" features.
* The 2017 standalone version cannot always read files created by newer versions of Sketchup, including the online version. Someone recently posted a Sketchup file here on WoodworkingTalk, and I could not read it with my standalone version.
