### 10.3.8. SectorCut Feature

The SectorCut feature is used to generate a 3D hub sector by revolving a closed-loop sketch curve (existing in a constant-theta plane) about the machine axis. The resulting 3D hub is trimmed at the same theta extents as the StageFluidZone feature corresponding to the specified Blade/Splitter. The 3D hub is also trimmed, if necessary, by the hub curve belonging to the FlowPath feature corresponding to the specified Blade/Splitter.

The feature properties are as follows:

Table 10.2: Details View for SectorCut Feature

Details of [Feature Name]
Blade | [Blade or Splitter feature selection]
Sketch | [Sketch selection]
Flow Type | [Axial | Transitional | Radial]

A StageFluidZone feature must be present in the model above the position of the SectorCut Feature.

The Hub geometry will be placed in “Frozen” state to prevent merging with the Blade/Splitter geometry. If required, the Hub geometry can be merged subsequently by using an Unfreeze feature (see Unfreeze in the ANSYS DesignModeler User's Guide).

For the flow type:

- Select “Axial” for flow paths that are entirely parallel to the machine axis

- Select “Transitional” for flow paths that enter axially and exit radially or vice-versa

- Select “Radial” for flow paths that are entirely perpendicular to the machine axis
