What is the Vertex Bevel Tool in Blender?

The Vertex Bevel tool in Blender allows 3D modelers to chamfer, round, or smooth individual vertices on a mesh without affecting entire edges. Unlike traditional beveling that acts on full edge loops, vertex beveling creates new polygonal geometry directly around selected control points. This article covers how the Vertex Bevel tool works, how to activate it, its essential settings, and key use cases in 3D modeling.

Understanding Vertex Beveling

In standard Blender modeling, the Bevel tool (Ctrl + B) rounds off the sharp edges between faces. However, when working with flat planes, isolated points, or specific corners, edge beveling may not produce the desired geometry.

The Vertex Bevel tool specifically targets selected vertices. When applied, it splits a single vertex into multiple connected vertices, creating a flat chamfer or a smooth curve depending on your settings. This makes it an essential tool for hard-surface modeling, precision drafting, and low-poly art.

How to Activate the Vertex Bevel Tool

To use the Vertex Bevel tool, follow these steps:

  1. Switch to Edit Mode (Tab).
  2. Set your selection mode to Vertex Select (Press 1 on your keyboard).
  3. Select the vertex or vertices you want to bevel.
  4. Activate the tool using one of these methods:
    • Keyboard Shortcut: Press Ctrl + Shift + B.
    • Menu Option: Go to the top menu bar and select Mesh > Vertices > Bevel Vertices.
    • Alternative Shortcut: Press Ctrl + B to start a standard bevel, then press V to toggle Vertex mode.
  5. Move your mouse away from the target to adjust the size of the bevel, and click to confirm.

Key Tool Settings and Controls

Once you initiate a vertex bevel, you can adjust several parameters in real-time or via the Adjust Last Operation panel (located in the bottom-left corner of the viewport):

  • Width / Offset: Controls the distance the new vertices move away from the original point, determining the overall size of the bevel.
  • Segments: Controls the smoothness of the corner. Rolling your mouse wheel up or increasing the segment count adds more geometry, converting a flat diagonal chamfer into a smooth curve.
  • Shape: Adjusts the profile curve of the bevel. A value of 0.5 creates a round curve, lower values pull the shape inward (concave), and higher values push it outward (convex).
  • Vertex Affect Mode: Toggles between beveling vertices or edges if you opened the tool via the standard bevel menu.

Practical Use Cases

  • Rounding Flat Plane Corners: When creating 2D profiles, panels, or UI elements on a single flat surface, vertex beveling easily rounds out sharp 90-degree corners.
  • Preparing Geometry for Inset/Extrusion: Beveling a single vertex on a flat face creates an n-gon or octagon that can quickly be turned into a circular hole using tools like LoopTools Circle.
  • Creating Smooth Transitions on Beams and Frames: You can bevel isolated vertices along a wireframe mesh before converting the edges into curves or pipes via skin modifiers.
