[Soc-2012-dev] Precision Modelling tools - week 11

Week 11 Report
This week I started by fixing up the parallel snapping, and removing the
requirement for the mouse to be near the parallel for the snap point to get
created.
Face snapping is back. Planar and perpendicular snapping are implemented.
Drawing is working, kinda! Dynamic menus are a work in progress at the
moment, and will be sure to change when I start bringing in multi-snapping
next week.
It's been tricky to decide which snapping options should be available to
the user when snapping between different object types. This is something
that really requires user feedback (arrrgg I still haven't got a build out
:S). Sooo... I'm going to release a build for
windows and linux tomorrow with a nicer wiki version of this progress
report with screenshots so people can confidently try it out.

Next Week's Plans:
I have run into an issue which will need some resolving next week:
With parallel and planar snapping it is often desirable to snap parallel to
the parallel of geometry which might actually be selected and part of the
transform. ie: transform line parallel to itself, or face planar to itself,
or vertex planar to a face which itself is attatched to.
The list goes on. This weekend I have initially tried to solve for the
vertex case by storing the position of the vertex before transformation,
but have come to realise the the problem is much bigger than this! Will
need to talk to Martin about the possibility of creating a copy of the
untransformed mesh to conduct snapping on for this option. This also
relates to a request that someone had on blenderartists where the other
snapping modes could be conducted on the mesh in its state before the
transformation.
I'll need to fix up a few todo's and issues that have arrived this week,
and start having a proper crack at multi-snapping, aiming to have
something usable (and useful) by the end of the week. I would also like to
make a start on the pen tool. Perhaps just getting the barebones draw and
snap between vertex working.
