Sheet Metal Corner Break

To create a filleted corner break on a sheet metal model:

1. While in a Part Studio with an existing sheet metal model, click Corner break ().

   

2. Select Fillet for the corner break type.
3. Select a corner edge or vertex on the sheet metal model in the graphics area. A corner edge or vertex can also be selected in the flat view section of the Sheet metal model and flat view.
4. 选择测量类型，可以是：
   1. Radius - Specify the radial measurement of the fillet.
   2. Width - Specify the distance between the two ends of the fillet (a constant width).
5. 选择控制类型：
   • Distance - Fillet has a circular edge with the radius value entered. Onshape remembers this value when creating new fillets.
   • Conic - Fillet has a conical edge with the radius value you enter and optionally a Rho value to define the style of the fillet:

     

     Rho values: 0.25 (left; elliptical curve): 0.5 (middle; parabolic curve); 0.999 (right; hyperbolic curve - zoomed in)

   • Curvature - Fillet matches the curvature of the surrounding edges with a radius value you enter and optionally a Magnitude value between 0 and .999 to adjust the tangency. Turn Zebra stripes on (from the Show analysis tools menu) to see the tangency more clearly:

     

   输入半径值时，您也可以使用下图中以箭头指示的拖动操纵器来可视化圆角并得到估计值：

   

   Onshape remembers the selection for Measurement type and value and opens the dialog with the last selected option in subsequent operations.

6. Check Asymmetric and enter a Second radius to have a different fillet edge radius value on one end of the filleted edge. Click the Flip asymmetric arrow to use the other end of the fillet as the second (asymmetrical) fillet edge.
7. By default, Allow edge overflow is disabled. Check to allow the tangent edges to be 'deleted' from the fillet surface, if necessary. The edges that are generated by default strictly constrain the direction of the fillet along the fillet edges. When Allow edge overflow is enabled, the fillet can modify edges on the face created by the fillet to make a smooth, continuous surface. When the option is unchecked, the edges on the filleted face are preserved, resulting in a more free-flowing part.

   Click the Allow edge overflow dropdown to open a field where you can select edges to keep.

8. Click the checkmark () to accept the new Corner break feature.

To create a chamfered corner break on a sheet metal model:

1. While in a Part Studio with an existing sheet metal model, click Corner break ().

   

2. Select Chamfer for the corner break type.
3. Select a corner edge or vertex on the sheet metal model in the graphics area. A corner edge or vertex can also be selected in the flat view section of the Sheet metal model and flat view.
4. 选择测量类型，可以是：
   1. Offset - Sets the distance entered in the Distance field from the starting edge to the chamfer. This option is edge dependent; computation starts at the first selection and then progresses through the chain.
   2. Tangent - Sets the distance entered in the Distance field from the intersection of the tangent of the two adjacent faces to the chamfer. This option is NOT edge dependent.
5. Select a Chamfer type:
   • 相等的距离 - 倒角将在两个方向上从边延伸相等的距离。
   • 两个距离 - 倒角将在每个方向上延伸不同的距离。
   • 距离和角度 - 倒角将在一个方向上延伸指定距离，在另一个方向上延伸指定角度。
     

     Onshape remembers the selection for the Chamfer type and opens the dialog with the last selected option in subsequent operations.

6. Enter the Distance(s) for the chamfer. Onshape defaults to 45 degrees for the angle, but remembers the last inputted distance value for Equal distance and Distance and angle chamfers.
7. If you selected Two distances or Distance and angle, click the arrow button to flip the direction of all edges, or specify individual edges to flip in the Direction overrides field.
8. Click the checkmark () to accept the new Corner break feature.

• After a Corner break feature is applied, all model Joints' Type (Rip or Bend) and Style (Edge joint or Butt joint) are no longer editable in the Sheet metal table and flat view. It is recommended to add any Corner break features after finalizing all edits to the Sheet metal model's flanges and joints.

• You can use Corner break to apply fillets or chamfers to Bend relief edges and vertices, in addition to corners:

  

• You cannot add multiple fillets, chamfers, or a combination of both on corners using a single Corner break feature. Create an additional Corner break feature to add an additional fillet or chamfer to any vertex or edge of a previously-existing Corner break feature:

当钣金模型处于活动状态时（在创建或编辑的过程中），可使用其他工具：

• 法兰 - 为选定的每条边创建壁，通过折弯连接到选定的边。
• 卷边 - 在现有钣金零件上，为选定的每条边/每个面创建卷边。
• 薄片 - 向钣金法兰添加薄片。
• 折弯 - 沿参考线折弯钣金模型，并提供其他折弯控制选项。
• 制作接头 - 将两个壁的交点转换为接头特征，使其成为折弯（由圆柱几何图元接头的壁）或接缝（两个壁之间的小间隙）。
• 拐角 - 修改拐角类型和止裂槽比例。
• 折弯止裂槽 - 修改折弯止裂槽（折弯末端与自由边相交处的小切口）、深度和止裂槽宽度。
• 修改接头 - 修改现有接头，例如将折弯转换为接缝。当前，可以通过展开视图表使用此功能。
• Corner break - Break the corner on existing sheet metal parts by applying a fillet or chamfer. Select a corner edge or vertex and specify corner break type and distance. It is recommended to use this feature after all flanges and joints of the Sheet metal model are finalized.
• 钣金表格和展开视图 - 打开和关闭接缝/折弯表以及钣金模型展开图样的可视化。使用此表将接缝与折弯互相转换。
• 结束钣金模型 - 关闭（取消激活）钣金模型；在特征列表中创建特征。
