### 10.5.4. Loading and Modifying Blades from ANSYS BladeGen

If you create a blade from scratch in BladeEditor, or if you convert a BladeGen BGD file into BladeEditor features (that is, load a BGD file) by clicking , then you can modify the blade by editing any of the features in the Tree Outline. By contrast, if you instead import a blade from BladeGen (for example, by clicking (see Importing Blades from ANSYS BladeGen)), the blade will be dependent on the BladeGen BGD file, but you can still modify the `HubProfile` sketch that appears under the associated `MerPlane` feature.

Note: If you edit the hub sketch, make sure to maintain a closed edge loop when modifying this sketch or the hub body will fail to be generated. You can check the loop while editing the sketch by right-clicking in the viewer, choosing Select Loop/Chain and then selecting an edge of the loop. This will highlight the loop and let you inspect it in order to make sure that it is uniquely closed.

You can modify the blade geometry using any of the standard DesignModeler geometry features. Some examples of the latter are:

- Adding edge blends to the blade geometry

- Trimming the blade and/or hub bodies

- Adding extrusions

#### 10.5.4.1. Limitations of Loading BladeGen cases into BladeEditor

The following BladeGen model features are incompatible with BladeEditor, and prevent successfully loading a BladeGen case into BladeEditor.

- trim profile

- End Angle definitions

- %Cam vs %Cam thickness distributions

- layers other than constant span fraction layers

- thickness of types `Normal to Camber Surface` or `Tangential`
