Loop Cut and Slide splits a loop of faces by inserting a new edge loop intersecting the chosen edge.

Usage

The tool is interactive and has two steps:

  1. Pre-Visualizing the Cut

    After the tool is activated, move the cursor over a desired edge. The cut to be made is marked with a magenta colored line as you move the mouse over the various edges. The to be created edge loop stops at the poles (tris and n-gons) where the existing face loop terminates.

  2. Sliding the new Edge Loop

    Once an edge is chosen via LMB, you can move the mouse along the edge to determine where the new edge loop will be placed. This is identical to the Edge Slide tool. Clicking LMB again confirms and makes the cut at the pre-visualized location, or clicking RMB forces the cut to exactly 50%. This step is skipped when using multiple edge loops (see below).

Options

These options are available while the tool is in use, and later in the Adjust Last Operation panel.

Number of Cuts Wheel or PageUp / PageDown

After activating the tool, but before confirming initial loop location, you can increase and decrease the number of cuts to create, by entering a number with the keyboard, scrolling Wheel or using PageUp and PageDown.

Opomba

When creating multiple loops, these cuts are uniformly distributed in the original face loop, and you will not be able to control their positions.

Smoothness Alt-Wheel

Smoothing causes edge loops to be placed in an interpolated position, relative to the face it is added to, causing them to be shifted outwards or inwards by a given percentage, similar to the Subdivide Smooth tool. When not using smoothing, new vertices for the new edge loop are placed exactly on the preexisting edges. This keeps subdivided faces flat, but can distort geometry, particularly when using Subdivision Surfaces. Smoothing can help maintain the curvature of a surface once it is subdivided.

Falloff

Falloff type for Smoothness, changes the shape of the profile.

Factor

Position of the edge loop relative to the surrounding edge loops.

Even E

Only available for single edge loops. This matches the shape of the edge loop to one of the adjacent edge loops. (See Edge Slide tool for details.)

Flip F

When Even is enabled, this flips the target edge loop to match. (See Edge Slide tool for details.)

Clamp

Clamp within the edge extents.

Correct UVs

Corrects the corresponding UV coordinates, if these exist, to avoid image distortions.
