Shift-Ctrl-B (Bevel Vertices)
The Bevel tool allows you to create chamfered or rounded corners on geometry. A bevel is an effect that smooths out edges and corners.
Real world edges are very seldom exactly sharp. Not even a knife blade edge can be considered perfectly sharp. Most edges are intentionally beveled for mechanical and practical reasons.
Bevels are also useful for giving realism to non-organic models. In the real world, the blunt edges on objects catch the light and change the shading around the edges. This gives a solid, realistic look, as opposed to un-beveled objects which can look too perfect.

Usage – Використання#
The Bevel Edges tool works only on selected edges with exactly two adjacent faces. It will recognize any edges included in a vertex or face selection as well, and perform the bevel the same as if those edges were explicitly selected. In «vertex only» mode, the Bevel Vertices tool works on selected vertices instead of edges, and there is no requirement about having any adjacent faces. The Bevel tool smooths the edges and/or «corners» (vertices) by replacing them with faces making smooth profiles with a specified number of segments (see the options below for details about the bevel algorithm).
Use Ctrl-B or a method listed above to run the tool. Move the mouse to interactively or type a number to specify the bevel offset, and scroll the Wheel to increase or decrease the number of segments (see below).
Примітка
Normal (edge) beveling only works on edges that have exactly two faces attached to them. Vertex beveling has no such restriction.
Options – Опції#
- Affect V
- Vertices – Вершини
Only the areas near vertices are beveled, the edges remain unchanged.
- Edges – Краї
Bevel the edges, creating intersections at vertices.
- Width Type M
Selects how the Width value controls the size of the bevel. According to the selection, the width is:
- Offset – Зсув:
The distance from the new edge to the original.
- Width – Ширина:
The distance between the two new edges formed by the bevel (or the edges on either side of the bevel if there is more than one segment).
- Percent – Відсоток:
The percentage of the length of adjacent edges that the new edges slide.
- Absolute – Абсолютно:
The exact distance along edges adjacent to the beveled edge. A difference from Offset is visible when the unbeveled edges attached to beveled edges meet at an angle besides a right angle.
For vertex-only bevels, the Offset and Depth types measure from the original vertex. The Width type is measured from a new vertex to the center of the new face (as half the Width).
- Width A
You can change the bevel width by moving the mouse towards and away from the object, a bit like with transform tools. The exact meaning of the value depends on the Width Type option (see above). As usual, the scaling can be controlled to a finer degree by holding Shift to scale in 0.001 steps. LMB finalizes the operation, RMB or Esc aborts the action.
Примітка
When multiple edges are beveled at the same time, it is sometimes impossible to make the width match the above definition on all edges simultaneously. Bevel tries to compromise in such cases. Sometimes turning off Loop Slide (see below) can make it easier for Bevel to make the widths as specified.
- Segments S
The number of segments in the bevel can be defined by scrolling the mouse Wheel to increase or decrease this value. The greater the number of segments, the smoother the bevel. Or press S to change the number with mouse movements, as well as numeric input.
Alternatively, you can manually enter a segment number value while using the tool, or in the Mesh Tool options panel after using the tool.
Bevel with four segments.#
- Shape P
This is a number between 0 and 1 that controls the shape of the profile (side view of a beveled edge). The default value, 0.5, gives a circular arc (if the faces meet at right angles). Values less than that give a flatter profile, with 0.25 being exactly flat, and values less than that giving a concave bevel. Values more than 0.5 give a more convex profile. Similarly as Segments it can be set with mouse movements and numeric input after toggling P.
- Індекс Матеріалу – Material Index
The Material number specifies which material is assigned to the new faces created by the Bevel tool. With the default, -1, the material is inherited from the closest existing face («closest» can be a bit ambiguous). Otherwise, the number is the slot index of the material to use for all newly created faces.
- Harden Normals H
When enabled, the per-vertex face normals of the bevel faces are adjusted to match the surrounding faces, and the normals of the surrounding faces are not affected. This will keep the surrounding faces flat (if they were before), with the bevel faces shading smoothly into them. For this effect to work, a mesh must have custom split normals. As a convenience, that option will be enabled for you if it is not already when you enable Harden Normals here.
- Clamp Overlap C
Лімітує ширину кожного скошеного ребра так, що ребра не можуть спричиняти перекривні перетини з іншою геометрією.
- Ковзання Петлі – Loop Slide
If there are un-beveled edges along with beveled edges into a vertex, the bevel tries to slide along those edges when possible. Turning the option off can lead to more even bevel widths.
- Mark
- Seams U
Якщо ребро зі швом перетинається з ребром без шва і ви скошуєте їх разом, то ця опція буде підтримувати очікуване поширення швів.
- Sharp K
Подібно до Mark Seams, але для гострих ребер.
- Miter Outer O
A miter is formed when two beveled edges meet at an angle. On the side where the angle is greater than 180 degrees, if any, it is called an outer miter. This option specifies the pattern that Blender uses at an outer miter.
- Sharp – Гостро:
Ребра зустрічаються у точці під гострим кутом без жодних добавних вершин, уведених на ребрах.
- Patch – Латка:
Edges meet at a sharp point but in addition, two extra vertices are introduced near the point so that the edges and faces at the vertex may be less pinched together than what occurs in the Sharp case.
- Дуга – Arc:
Two vertices are introduced near the intersection, and a curved arc joins them together. The Spread slider controls how far the new vertices are from the intersection. The Profile curve widget controls the shape of the arc.
The current choices are shown in this diagram, where the outer miter is along the horizontal surface.
- Inner I
An Inner Miter is formed when the angle between two beveled edges is less than 180 degrees. This option specifies the pattern Blender uses at an inner miter. The options are the same as for Outer Miter, except that Patch makes no sense and is therefore omitted. Inner miters are shown in the following diagram, where two inner miters are on the vertical surfaces.
- Розтікання – Spread
The value used to spread extra vertices apart for Outer and Inner Miters. This option is available when Miter Inner is set to Arc.
- Intersection Type N
When more than two beveled edges meet at a vertex, a mesh is created as a way to complete the intersection between the generated geometry. This option controls the method used to create that mesh.
- Заповнити Сіткою – Grid Fill:
The default method for building intersections, useful when a smooth continuation of the bevel profile is desired. Without Custom Profile enabled, the curve of the profile continues through the intersection, but with a custom profile it just creates a smooth grid within the intersection’s boundary.
- Cutoff – Відріз:
Creates a cutoff face at the end of each beveled edge coming into the vertex. This is most useful for custom profiles when the new intersection is too complex for a smooth grid fill.
При тристоронньому перетині, коли кутки ізсередини профілів відрізу граней зустрічаються у тій самій локації, жодна центральна грань не створюється.
Напрямок відрізу граней залежить від нормалі оригінальної вершини.
- Сила Грані – Face Strength
Set Face Strength on the faces involved in the bevel, according to the specified mode. This can be used in conjunction with a Weight Normals Modifier (with the Face Influence option checked).
- None – Нема:
Не задається сила грані.
- New – Нове:
Задається сила грані нових граней уздовж ребер на «Середньо» – Medium, і сила граней нових граней у вершинах на «Слабко» – Weak.
- Задіяне – Affected:
На додаток до тих, що задані у випадку New, також задається для граней, суміжних до нових граней, сила Strong.
- All – Усе:
In addition to those set for the Affected option, also set all the rest of the faces of the model to have strength Strong.
- Profile Type Z
- Superellipse:
Creates a bevel with a uniform concave or convex curve.
- Кастомне – Custom:
Віджет кастомного профілю.#
This Віджет Кривої – Curve Widget allows the creation of a user-defined profile with more complexity than with the single profile parameter. The modal tool allows toggling the custom profile, but the shape of the profile is only editable in the options panel after the operation is confirmed.
The profile starts at the bottom right of the widget and ends at the top left, as if it were between two edges intersecting at a right angle. Control points are created in the widget and then the path is sampled with the number of segments from the Bevel modifier.
Примітка
The Profile curve widget stays active when miters are enabled because it still controls the shape of the miter profiles.
- Presets – Передустави
The Support Loops and Steps presets are built dynamically depending on the number of segments in the bevel. If the number of segments is changed, the preset will have to be re-applied.
- Sampling – Відбір
Samples will first be added to each control point, then if there are enough samples, they will be divided evenly between the edges. The Sample Straight Edges option toggles whether the samples are added to edges with sharp control points on either side. If there aren’t enough samples to give each edge the same number of samples, they will just be added to the most curved edges. So it is recommended to use at least as many segments as there are control points.
