Manipulators of Chamfer

Chamfer manipulators have a shape of a blend surface's cross-section (straight line segment) with two square markers at endpoints.

On straight edge a single manipulator appears at the midpoint. On curved open edges two manipulators split blend surface in equal length sections. On curved closed edges either two or four manipulators might appear in different cases.

In chamfer by offsets and chamfer by offsets along faces modes each of two manipulator's endpoint markers represents its own offset value (Offset 1 or Offset 2).

Moving the mouse cursor over any of a manipulator's endpoint markers leads to a radius icon appearing near the cursor. Dragging the mouse while holding, when radius icon is present, leads to a corresponding Offset value change in accordance with the cursor movement. Depending on the Common Properties checkbox condition, Offset changes either for all edges at once (which affects the appearance of their manipulators) or for the corresponding edge only.

In chamfer by length and angle mode manipulator's way of operation depends on the condition of the checkbox which is located to the left side of the Angle field on the Edges tab of the Parameters window. If checkbox is enabled (by default) both endpoint markers represent Length value, while Angle does not depend on the manipulators usage. Disabling the checkbox makes one of the endpoint markers represent Length and other represent Angle. As to the rest manipulators in chamfer by length and angle mode are used in a similar way as in other types of chamfer modes.
