The Bevel command chamfers/fillets mesh or SubD edges with the specified segments.

### Input

* Mesh and SubD edge

#### **Steps**

1. Select one or more edges and press Enter.
2. Move the cursor to decide the bevel amount and click.\
   Or, enter a number and press Enter.\
   The number can be an absolute distance or a proportional value based on the OffsetMode setting.

### Command-line options

**Edge selection mode**

* **(Default)**

  Click selects a single edge. Double-click selects an edge loop.

  Ctrl+click deselects a single edge. Ctrl+double-click deselects an edge loop.
* **EdgeLoop**

  Click an edge to select an edge loop.

  The clicked edge displays a brighter highlight than the other edges in the loop.

  Ctrl+click the same edge to deselect the loop.

#### **Segments**

The number of new faces added over the beveled edge.

#### **OffsetMode**

* **Proportional**

  The bevel amount is proportional to each crossing edge length. The input number should be between 0 and 1.0.

* **Absolute**

  The bevel amount is same for all edges. The input number is a distance in the model unit.

#### **Straightness (0-1.0)**

0 creates the most rounded bevel. More segments are required.

1.0 creates a flat bevel.

#### **WeldAngle (Mesh only)**

The tolerance in degrees for welding mesh edges.

#### **RetainShape (Mesh only)**

All new vertices added to the mesh will be on the original mesh edges.

#### **KeepCreases (SubD only)**

Specifies if creased edges will be retained.
