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

    The tool is interactive and has two steps:

    1. 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 . 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 调整上一步操作 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.

    Note

    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 pre-existing edges. This keeps subdivided faces flat, but can distort geometry, particularly when using . 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.)

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