Extrude vertices along edges

Question

I've been looking for answer on this site, but didn't find a solution, or dumb enough not to apply for my situation. I need to extrude vertices along already created edges? Is there any way to do that?

I don't know how to extrude them into the said direction or if it's at all possible. But you can move them by double tappin g and holding alt. Then you can add a loopcut in the middle. — AzulShiva, Feb 25 '19 at 06:32
you are making your question difficult, do you just need to extrude vertices? — Yash, Feb 25 '19 at 06:59
I need to extrude them along given edges. I tried moving them, but loop created after that has different topology, than i need. — Victor Naumov, Feb 25 '19 at 07:06
Probably i need to create the new path for transformation, but i don't understand how to do it in a correct way. — Victor Naumov, Feb 25 '19 at 07:07
Thanks, moonboots, i will look for alternatives. Can You please advise how to do it alternatively, if any? — Victor Naumov, Feb 25 '19 at 07:46
I told you how you can do it alternatively. That will work fine. — AzulShiva, Feb 25 '19 at 08:23
You can slide vertices along their edges out beyond an existing boundary if you release the clamp: see this answer — Robin Betts, Feb 25 '19 at 10:13

Three different ways to do this currently. Options #1 and #2 only allow to specify distance factors relative to edge length. Option #3 should allow absolute units.

Use vertex slide: Press G,G twice to activate Vertex Slide, while the cursor is hovering the edge with the desired direction. Afterwards press C to deactivate clamping and allow extending beyond current position.

Scale in relation to the other vertex: Place you 3D cursor at the other end of the edge by snapping it to the vertex with Shift+S > Cursor to Selected. Change the Transform Pivot to the 3D Cursor and then scale the opposing vertex with S.

Use a custom transform Orientation: Select the edge with the desired direction. In the 3D View Properties Area from Transform orientations chango to local and press + to add a new one. Select it from the list (should be named Edgeby default), then select your vertex and move it by using G then tapping twice the desired axis to move in local coordinates, in this case Y,Y.
