How can I grab a bunch of vertices in an object (edit mode) and get them to line up along the x axis?
You can sellect one vertx (ore more, if they are in same X location) then hit the N-key for Transform Properties and type new X possition.
I’m not aware of any diferent way.
you could try to scale them down to zero on one axis !
Both are good solutions.
The N-key to show properties only works with a single vertex. Otherwise, it teats them as a group with “median” position (moves them all around to the point, but does not flatten them out).
Scaling is works very well, although I can’t help thinking that I’m trying to slowly adjust the points beyond the last 0.001 scale. Is there a way I can scale them down and manually type in “0” for the x axis?
Edit: minor spelling
Select your verts, skey, xkey, 0key (zero key), enter.
Yeah - like that. 'course I knew that already (not)
…cheers - a cool trick and exactly what I was after.
