Metasequoia modeler tutorials and Keynote translated plugins

[Verdite]

Thats what i shouldve asked, because thats what i was looking for... But with the "cut a straight line" you can cut, then select the vertice, then move it to create an angled line.

I noticed someone mentioned about a feature in keynote that lets you hide an object? It'd be nice to be able to have say, spikes that appear from a monsters head when it attacks you.
