Cut UV Tool

Cut UV Tool#

The Cut UV tool is the primary tool in the UV Flow add-on, located in the Edit Mode toolbar. When activated, it provides a pre-selection highlight for edges and faces as you hover over your mesh.

Interacting with Edges#

You can interact with edges using the following actions:

  • Left Mouse Button (LMB): Mark edge as seam.

  • Alt + LMB: Clear edge as seam.

  • Double LMB: Mark loop as seam, stopping at other seams.

  • Shift + Double LMB: Mark entire loop as seam.

  • Alt + Double LMB: Clear loop as seam, stopping at other seams.

  • Alt + Shift + Double LMB: Clear entire loop as seam.

  • Drag LMB: Draw a marked seam path.

  • Alt + Drag LMB: Draw a clear seam path.

Seam Behavior#

  • When marking or clearing loops as seams, the seam will stop when it meets another seam.

  • While drawing to mark or clear seams, use the dots of neighboring vertices as targets. You can also erase by dragging backward toward the red dot.

Selecting Faces#

While using the Cut UV tool, you can also select faces:

  • LMB: Select a face.

  • Double LMB: Select the UV island.

Double-clicking to select a UV island is particularly useful for hiding or pinning sections of a mesh that you have already unwrapped.
