Bevel
Bevel edges on 3D geometry or round corners on 2D shapes.
What it does
Bevel softens hard edges and corners. On a 3D mesh it bevels the edges, carving a small strip along each sharp edge to catch light. On a 2D shape it rounds or chamfers the corners instead. One node reads the input and applies whichever applies.
Round mode gives a circular arc, Chamfer a flat cut. Custom takes a Curve node wired into Profile to drive the exact cross-section, anything from a gentle flare to a stepped notch.
When to use it
Mesh edges that should catch highlights rather than read razor-sharp.
Rounded corners on a 2D shape, with the same Width and Segments controls.
Bevelling sharp corners only, leaving gentle curves alone: keep Selection on Angle and tune the threshold.
A non-circular cross-section (flare, step, ogee): connect a Curve to Profile and switch Mode to Custom.
| Parameter | Type | Default | What it does |
|---|---|---|---|
input | Collection | — | Shape or Geometry to bevel |
profile | Curve | — | Custom bevel profile curve (0,0)→(1,1). Connect a Curve node. |
width | Number | 5 | Bevel width or corner radius |
segments | Number | 4 | Segments: 1 = chamfer, 4+ = smooth round |
mode | String | "Round" | Round = circular arc, Chamfer = flat cut, Custom = profile curve. One of: Round, Chamfer, Custom. |
limit_method | String | "Angle" | Angle = only sharp edges, All = every edge/corner. One of: Angle, All. |
angle_threshold | Number | 30 | Angle threshold in degrees |
clamp_overlap | Boolean | true | Prevent bevel overlap on short edges |
Gotchas
Selection defaults to Angle, so only edges and corners sharper than Angle Threshold are bevelled and smoothly curving areas are left alone. If part of a model is not bevelling, check whether its edges are actually sharper than the threshold, or switch Selection to All.
Segments controls smoothness. 1 segment gives a flat chamfer-style cut regardless of Mode; 4 or more gives a smooth rounded bevel.
Clamp Overlap is on by default and prevents bevels on short edges from crossing over each other. Turning it off can produce self-intersecting geometry on tightly packed edges.
Custom mode takes effect only once a Curve is wired into Profile. Without a connection it falls back to the same placement as Round mode. Add a Curve node and connect it before switching to Custom.
Worked example
Add a Bevel node and connect your mesh or shape to Input.
Raise Width to set how wide the bevel strip (or corner radius) is.
Raise Segments above 1 for a smooth round bevel instead of a flat chamfer.
Leave Selection on Angle and adjust Angle Threshold so only the intended corners catch the bevel, or switch to All to bevel everything.
For a custom cross-section, add a Curve node, connect it to Profile, and set Mode to Custom.
