BladeModeler contains a rich set of tools and functions for designing a turbomachinery blade from scratch,
CLICK using industry-specific tools, workflow, and language that the blade designer expects.
CLICK the user can re-design existing blades to achieve new design goals or create completely new blade designs from scratch.
CLICK When either re-designing or evaluating an existing blade design, BladeGen facilitates the import of blade geometry interactively or through user supplied files.

Create blades for multiple stages
Eventually all BladeGen functionality will be migrated to BladeEditor
Some parameters can be exposed in Workbench for design exploration/optimization
Provides geometry connection between BladeGen and DesignModeler
Allows for the import of multiple BladeGen models into one DesignModeler session
Allows for easy editing of blade geometry
Components from another CAD source can be imported and combined with blade geometry (i.e. A volute)
