[Bf-funboard] Snaps & Trims

[Karim Nassar]

I've put together a little page detailing some ideas on snapping & 
trimming of geometry gleaned from many years of CAD use. I think that 
such functions would be invaluable to the development of Blender as a 
Pro-level modeling tool (I know I could use them!).

Note that I've organized these ideas in a way they might appear to the 
user. Careful planning in implementation should make several of these 
tools trivial, as the code required to execute the functions will build 
upon itself.

As an afterthought, I suggest that even though many of the snaps can be 
executed currently by combining multiple steps (ie: snap Vertex To 
Vertex, by means of the Cursor), this is no reason not to implement a 
streamlined continuum of snap tools, since when such tools are needed, 
they are frequently needed repeatedly, and an automated 2-step tool will 
be superior to the "tool-combination" approach, and by building the 
"simple" snaps as discrete functions, the complex snaps & trims can be 
built more easily.

Thoughts?
