Miter Flange Limitations

  • You can edit the miter Bend Parameters, but after step-by-step recognition, the default values are restored.
  • To convert an imported model into a sheet metal part, FeatureWorks uses the SolidWorks API. If this API fails, FeatureWorks does not recognize the miter flange. To check if the API is working, open the imported part in SolidWorks and click Insert > Sheet Metal > Bends. If the operation fails, miter recognition also fails.
  • The miter flange sketch should have only one line and arc entity.
  • If the flange faces have internal loops, miter flanges are not recognized.
  • Miter flanges on multiple edges that are not recognized:
    • With the position type Material Inside.
    • With the position type Material Outside and relief type Tear.
Miter flanges on multiple edges with offset and relief (rectangular, obround, or tear) applied are not created with offset. The flange sketch is created at the start of the flange face with a zero offset value. Sketch of flange start face
Miter flanges with the position type Material Outside or Material Inside and with non-planar lateral faces are not recognized.

The highlighted lateral faces are non-planar, so the miter flange is not recognized.

Miter flanges are not recognized if the selected edges are separated by circular arcs tangential to them.
Circular edges separate selected edges
If the flange/bend faces are trimmed off due to feature interaction or another reason, miter flanges are not recognized. Miter_TrimmedFaces.gif
Miter flanges on multiple edges are recognized incorrectly for these conditions:
  • Relief type Obround
  • Obround is overlapped by the bend connected to the flange.
Incorrectly recognized as two half obrounds
Redundant faces/edges are merged when you run FeatureWorks. For miter flanges on multiple edges, if the lateral faces are split, they are combined to form a single face. Miter_RedundantFaces.gif  
Miter flanges with a non-planar start lateral face and a planar end lateral face are not recognized.

In the example, if you select the flange faces in the clockwise direction, recognition is successful, while counter clockwise selection fails.

Planar face Non-planar face
For miter flanges created on split edges, after step-by-step recognition, the two split edges merge into a single edge and the geometry changes.
