Chamfers and
fillets don't have to be created time-consuming in the sketch, but you work
directly in the 3D view and can edit several edges in the same
course.
Example:
Select the
desired face and in the context menu of face to edit, click on New Chamfer/Fillet....
New Chamfer/Fillet...
In the dialog
Chamfer/Fillet, adjust the settings if
needed and click on OK.
