PartDesign Chamfer

Description
This tool creates chamfers on the selected edges of an object. A new separate Chamfer entry (followed by a consecutive number if there are already existing chamfers in the document) is created in the Project tree.

Usage

 * Select a single edge, multiple edges or a face on an object, then start the tool either by clicking the button or using the menu . In case you selected a face or a 3D object  all its edges are respected for chamfering.
 * In the appearing Task panel you can define the chamfer in 3 ways:
 * : The chamfer edges are equally distanced from the body edge.
 * : The distances of the chamfer edge to the body edge are specified. The distance direction can be flipped.
 * : One distances of the chamfer edge to the body edge is specified. The second chamfer edge is defined by the angle of the chamfer. The distance direction can be flipped.
 * If you want to add more edges or faces click the button and select edges and/or the faces.
 * After clicking the button you can add all edges of the object by right-clicking and selecting  from the context menu.
 * If you want to remove edges or faces
 * either select the edge/face in the list of the dialog and press the key. Note: Since there must be at least one edge for the feature, the last remaining edge or face in the list cannot be removed.
 * or click the button. All edges and faces being previously selected are highlighted in purple. Select the edge or the face to be removed.
 * Ensure Use all edges checkbox is unchecked or else some widgets in the dialog will be disabled.
 * Click to validate.
 * For a chain of edges tangential to one another, one single edge can be selected; the chamfer will propagate along the chain.
 * To edit the chamfer after the function has been validated, either double-click on the chamfer label in the Project tree, or right-click on it and select.
