Fan or propeller blades are aerodynamic shapes. To have a functional fan or propeller blades you will need to do some calculations or you might already have the data configured for your projects. In this tutorial I will only create a shape from my imagination without a proper dimension. Here's where I'll start:
Start your CATIA program and go to the Part Design workbench (Start > Mechanical Design > Part Design). I will start by creating the hub for the blades to be connected to. Select the zx-plane and start the Sketcher workbench. Draw something like I draw in the 1st picture.
Then use the Join tool on the Operations toolbar (Insert > Operations > Join) for the Fill and Multi-Section Surface to make them become 1 entity.
