2 basic questions - Snap plane to edge, proportional loop cut

[LIST=1]

  • I want to snap a plane to an edge, as if the horizontally-aligned rafter in this screenshot is resting on the vertically-aligned 2x4 below it.

http://www.lepertheory.net/%7Edavec/images/Snaphelp.pngI can get it really, really, close by zooming in, but it’s not perfect, and besides, I don’t have a vertex there to be able to verify it even if I got something that looked perfect.
A better perspective, but you can’t see the edges/faces that need to snap.

Whatever happened with that proportional loop cut tool that was in blender 2.4? http://wiki.blender.org/index.php/Doc:2.4/Manual/Modeling/Meshes/Editing/Edges

I’ve never had the opportunity to use it, but if the same stuff still exists in 2.6, I can’t find it, but it’d really come in handy when trying to make straight cuts in 2x4s that have non-straight cuts.

Any help you can give is appreciated, thanks!

For the snapping, maybe try the Align tools addon (should be in most recent builds - just enable in user prefs). I think that will help.

Are you looking for the Ctrl-R (+mousewheel for no. of cuts) loopcut tool?

Sorta. I know about the tool, but, say you have a 2x4. One end is cut at a 90 degree angle, the other is cut at a 50 degree angle. If you loopcut the long edge, you’ll get 70 degree angle directly in the center, and as you slide the loop toward one edge or the other it’ll approach that edge’s angle. And that’s cool, normally, but in this instance I want to base the cut off one or the other side’s angle. Or, as shown in the image below, preserve all the angles when making complex cuts.


Also, thanks for the help on the snap addon, checking it out now!
