Live selection magnet snapping but only on one axis

[Anonymous]

Hey, for the past few hours I've been trying to do this seemingly simple task of snapping a few points to the bottom of an object. I discovered the live magnet tool. Would work perfectly if it worked by locking to the one axis.

"screenshot_5" = example original position. Goal is to move selected points up to the object above.

"screenshot_6" = result when moving on yellow / y axis, with live selection magnet turned on. It is possible to guess if it has gone up perfectly straight, but not ideal. (This method requires guessing if the points have gone directly up, and not to either side)

"screenshot_7" = intended result example. Simply done by moving the yellow / y axis up. (This method requires guessing if the points intersect perfectly)

Same issue when using "object" axis orientation on move tool, which will move diagonally, would like to work that out too.

How do I snap those points to that object above? 

Thanks

I think your're missing vertex points on the other mesh where it could snap to. Try doing an edgeloop as shown in the picture below and try again.

Thanks for the response, that sort of works, however is there another way, as that requires guessing where to apply the loop cut, especially if moving diagonal, and also loopcuts that I don't actually want.

Sorry I dont quite understand what youre actually trying to do? You just want those two vertex points touching the bottom of that other mesh correct? If you have to be extremely accurate you can go into your orthographic view and place the loopcut exactly where you want it to be (dont forget to turn on wire frame mode to see how everything lines up.)

Yes but I want the joint to join exactly where it reaches when sliding on that specific axis. There should be a better way than to do this loop cut cheat.

Okay I'm out of ideas then. Thats atleast how I would do it: 
>Move the two vertex points up to where you want them to be (roughly)
>Go to orthographic view and wireframe mode and put the edge loop exactly where the two vertex points are (zoom in alot)

>Snap the the vertex points to the newly created ones

>Delete the edge loop

I think that would be pretty accurate.

Anyway if you find a better solution let me know!

Just use curve snap instead of vertex snap. Hold down C while the Y axis is highlighted and middle click wiggle by the curve.

Easy as that
