    First use Snap All Axes, only then use it "V"

    I been working with the new tool system for a few days...
    And I'm sad to say that this comes with the old problem where you have to zoom in to get accuracy, as the vertex snapping seems to relies on how far you are from the objects.

    So if you want 100% accuracy, zoom in as you can.
    That's not good.

    Check this out:

    Thank you!!!

    Tested it as well with the new tool system as you said and it worked!
    (I'm using the latest version of Unity, Unity 2017.3.1f1)

    Finally! I'm so happy.
    Seems like no more gaps in my projects.
    Anyways, the bug should be fixed soon.

    Looks like I found out the solution. I'm using the latest version of Unity (2017.3.0p3). In the top left corner select the new tool system (Move Rotate or Scale selected objects).

    With this system I can successfully align the meshes using Vertex Snap Tool ('V' button). With simple 'Move Tool' I have the same issue as the topic starter.

    Priority should be changed to Critical :(
    Can't work with level design with this issue...
