You can still download Sketchup Make 2017, and it is very robust with nearly every tool in the latest pro version, and 100% free. You have to do a little digging to find it though, they won't take you directly to the link when you click download. And I think you still have to do the 30 day free trial of 2017 pro before the regular "make" version starts working, but 2017 pro drawings will work in the "make" version. However, 2018 stuff you do on the free trial or on the free web version will not work in 2017.
And all the sketchup versions will let you do a pull, you just have to make sure your outline is 100% connected at all points. If there is a gap (like in your autocad drawing above) you can't do a pull, and it won't tell you why, it just won't work.
Although sketchup is a relatively easy tool, it is so different from other CAD software that it has a steep learning curve. Once you get past it, it gets super easy to use. VERY good to use for woodworking projects.
