Chamfer removes or adds a flat section from a selected edge to create a beveled surface between the two original faces common to that edge. You obtain a chamfer by propagation along one or several edges.
In the Chamfer.x dialog box, you can create a chamfer using
various options:
Mode
The following modes are available:
Length and Angle (Default mode, that is intersection of the two
perpendiculars of the normal lines): Enter a length value and an angle value.
Length1 and Length2: Enter two length values.
Important:
The
Symmetric extent
option appears. Select it to define the same value for both lengths (Length
2 is no longer available).
Chordal Length/Angle: Enter a chordal length value (that is the chamfer width) and an angle value.
Note:
Width = Lenght / cos (Angle)
Height/Angle: Enter a height value (i.e. distance between the intersection of the two adjacent faces and the chamfer face) and an angle value.
Note:
Height = Lenght * sin (Angle)
Hold Curve/Angle: In the Hold Curve box, select the edge or the curve up to which the height of the chamfer is to be calculated and enter an angle value.
Hold Curve/Length: In the Hold Curve box, select the edge or the curve up to which the height of the chamfer is to be calculated and enter a length value.
Important:
For creation of a chamfer, objects to chamfer and the hold curve must belong
to the same 3D part.
Propagation
Two propagation modes are available:
Minimal: Edges tangent to selected edges can be taken into account to some extent. The app continues creating chamfer beyond the selected edge whenever it cannot do otherwise. In the example below, the chamfer is computed on the selected edge and on a portion of tangent edges:
Tangency: Chamfers the entire selected edge as well as its tangent edges. It continues to create the chamfer beyond the selected edge until it encounters an edge that is non-continuous in tangency as shown in our example:
Other Options
Based on your requirement you can select the following options:
Reverse: This option is available in all modes. Selecting this reverses
the chamfer configuration.
Without Reverse
With Reverse
Corner Cap: This option is available in all modes. Selecting this caps
off the chamfer vertex.
Without Corner Cap
With Corner Cap
Symmetric Extent: This option is available only in the Length1/Length2 mode.
Selecting this creates a symmetrical chamfer, that is, Length2
is same as Length1. You need to define only
Length1.
How Chamfers are Computed
The system uses the intersection of the two perpendiculars of the normal lines on supports to define the distances and angle values. The edge between the two surfaces is not used by the chamfer computation.
option appears. Select it to define the same value for both lengths (Length
2 is no longer available).
