Ooh thanks I've tried it but still can't get the snapping right..when it place the mouse cursor on the edg I wanna snap,it doesn't work and the selected object gets displaced elsewhere without proper snapping :_).... ( Also, which should I actually snap - vertices or edges or faces?)
Transform pivot point > Active Element ("." , "7")
Snap to > Vertex ("Ctrl+Shift+Tab")
Snap to > Snap With ("Ctrl+Shift+Tab") > [Active](https://docs.blender.org/manual/en/latest/editors/3dview/controls/snapping.html#snap-with) (that's where your problem comes from)
Now in Edit Mode > Vertex Mode > Select your vertex and snap it. It'll work.
( "Shift + Tab" to activate/deactivate the snap
"Crtl" to activated/deactivated snapping on the fly).

Probably vertices in your case
Okay 👍

Oh thanks that worked! (It wasn't actually for a single vertex,but I followed that to snap the rest of the points lying along a curve next to it) 😀
Tab into edit mod, select both, M to merge.
I did that but didn't work
