Jonathan Williamson demos a small but very useful new tool: Rip Edge (a working title, they don't seem to like that name much ;-). He was lucky enough to find Campbell Barton interested in adding this for him in just one day! How's that the for the power of an awesome community + open source?
This is a quick demo of the new beta tool, Rip Edge. The tool was proposed by yours truly and built by Campbell Barton. It allows you to quickly add new vertices to a face. This is particularly useful for adding new vertices to NGons.
