I don't know anything about this apart from that it used to be Free and it was a Goooooogle thing/app/other...so, is the paid version (Pro) worth the greenbacks (££$$) or should i not bother with it ?
I used it when it was free but haven't used it since it became $$$ to own. Still good software from what I see. I guess it depends on what you want to do with it. I prefer Fusion 360 and that still has a free version for hobbyists.
