Hi.
I made couple tools for those of you that came from more viewport centric apps, or just missed this functionality and don't know how to script/node it in Houdini.
Right now two are available.
1. CreatePolygon (currently, like 5 minutes ago, I uploaded v1.2, which still awaits to be approved)

2. AlignPoints v1.0

Test them and tell me what you think.
Have fun!
