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. 測定タイプを次のいずれかから選択します。
   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. 制御タイプを選択します。
   • 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:

     

   半径値を入力するときは、次の図に示す矢印で示されているドラッグマニピュレータを使用して、フィレットを視覚化し、推定値に近づけることもできます。

   

   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. 測定タイプを次のいずれかから選択します。
   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:
   • 等距離 - 面取りはエッジから両方向に等しい距離まで延長します。
   • 2 つの距離 - 面取りは各方向に異なる距離まで延長します。
   • 距離と角度 - 面取りは、一方向に指定された距離まで延長され、もう一方向は指定した角度だけ延長されます。
     

     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:
