How to Slide an Edge in Blender

Sliding an edge along a mesh in Blender is an essential technique for adjusting geometry without altering the overall shape or volume of your 3D model. This article provides a quick, step-by-step guide on how to use the Edge Slide tool, master its keyboard shortcuts, and utilize advanced sliding modifiers for precise topology control.

Using the Edge Slide Shortcut

The fastest way to slide an edge along adjacent faces is by using keyboard shortcuts in Edit Mode:

  1. Enter Edit Mode: Select your object and press Tab to switch to Edit Mode.
  2. Select Edge Mode: Press 2 on your top number row to activate Edge Select mode.
  3. Select the Target Edge: Click on the edge you want to move. To select an entire edge loop, hold Alt and click the edge.
  4. Activate Edge Slide: Press G twice (G + G).
  5. Position the Edge: Move your mouse to slide the selected edge along the surface of the adjacent faces.
  6. Confirm: Left-click to lock the edge into its new position, or right-click to cancel the action.

Alternative Activation Methods

If you prefer using menus or UI tools instead of shortcuts:

  • Menu Navigation: With the edge selected, go to the top header and select Mesh > Edges > Edge Slide.
  • Toolbar Tool: Select the Transform tool from the left toolbar, click and hold, then choose the Edge Slide tool from the flyout menu.
  • Secondary Shortcut: You can also press Shift + V to initiate the slide tool.

Advanced Edge Slide Modifiers

While actively sliding an edge (before left-clicking to confirm), you can press specific keys to toggle useful precision settings:

  • E (Even Mode): Press E to force the sliding edge to match the exact shape and angle of one of the adjacent edge loops.
  • F (Flip Side): While Even Mode is active, press F to switch which adjacent edge loop the sliding edge mirrors.
  • C (Toggle Clamp): By default, edges are clamped to the boundaries of the adjacent faces. Press C to disable clamping, allowing the edge to slide beyond the mesh boundaries.
  • Shift (Precision Mode): Hold Shift while moving the mouse to slow down the slide movement for fine adjustments.
  • Ctrl (Snapping): Hold Ctrl to enable snapping to increments along the slide path.
