Autodesk - Powershape

5-axis machining requires perfect surface continuity. PowerShape’s "ribbon surface" and "blend surface" tools allow machinists to fill holes and smooth transitions so that the ball-nose end mill doesn't chatter when hitting a bad edge.

Originally developed by Delcam (a UK-based leader in CAM software) and later acquired by Autodesk, PowerShape is a dedicated hybrid modeling software. Hybrid modeling means you can work with solid bodies, surfaces, and meshes (STL/OBJ) inside a single file without converting or "repairing" the data.

While tools like Inventor or SolidWorks rely on parametric history (changing a sketch changes the final part), PowerShape works more like a sculpting or repair shop. It is designed to fix corrupted CAD files, add complex manufacturing features (like draft angles and electrode geometry), and prepare 3D scan data for machining.

Since Autodesk is heavily investing in Fusion 360, many users worry that PowerShape is being abandoned. However, Autodesk has confirmed that PowerShape remains a critical "bridge" for high-end manufacturing because Fusion 360's parametric kernel (ASM) cannot yet handle the same level of corrupted mesh and surface repair that PowerShape's Delcam kernel can.

Currently, Autodesk is focusing on "Interoperability" – making PowerShape run as a background engine within Fusion 360 Ultimate. Expect to see less UI development in PowerShape, but deeper integration into the cloud-connected manufacturing workflow.

For injection molding and die casting, EDM electrodes are required to burn complex cavities into hardened steel. PowerShape Autodesk includes automated electrode design wizards. It extracts the "burn zone" from a model, creates the electrode head, adds a holder and a shank, and generates a setup sheet—all in minutes.
