moving a vertex along an edge

can this be done? I mean moving a vertex along one of the edges conecting it to other vertex, so that the particular edge retains its orientation and changes only in lenght?

To move a single vertex along an edge: Select the vertex you want to be stationary. Shift-S, snap the cursor to this stationary vertex. Shift-select the vertex you want to move. Use the 3D cursor as Pivot point, then S to scale.

Go to the link below where greybeard solved the problem and also posted a video clip showing how its done.

good method!

still it might get tedious, any other suggestions?

thakns a lot though.

edit: that was for CD38, let’s see that video.
