SurfacePsycho stands out in the Superhive library for keeping its shapes as Geometry Nodes, so blend files stay usable without the add-on. It's under heavy development, so treat it as an evolving tool and check the developer's page and GitHub for the latest status.
SurfacePsycho is a Blender add-on focused on surface design, with .step file import and export. It stores everything as Geometry Nodes, so blend files that contain SurfacePsycho shapes can be opened, shared and archived even without the add-on installed.
That storage approach is intentional. Because the shapes live as Geometry Nodes, there's no risk of losing data if the add-on isn't present, and your work doesn't depend on the developer continuing the project. Documentation is provided, and a demo video is available.
The add-on is under heavy development, so you can expect inconsistencies and incompatibilities between versions, and the developer welcomes feedback. It is released under the GPL license and lists Blender 4.1 as its supported version. The source is available on GitHub.
Surfacepsycho is best for surface design work in Blender, including hard surface, car design, industrial design, architecture and product design.
Surfacepsycho is completely free to download and use.
SurfacePsycho lists Blender 4.1 as its supported version and is marked as Blender extension compatible. The add-on is under heavy development, so you may run into inconsistencies and incompatibilities between versions, and the developer notes that feedback is appreciated. For the current state of compatibility with your Blender build, check the developer's page and the GitHub repository before installing. Its shapes are stored as Geometry Nodes, which keeps your files usable across setups.
SurfacePsycho stores everything as Geometry Nodes, which the developer designed so you don't lose data without the add-on. Blend files containing SurfacePsycho shapes can be opened, shared and archived even when the add-on isn't installed. The stated reasoning is that no one wants to depend on a single developer who could stop maintaining the project. This makes your saved work independent of whether the add-on is present, which matters given that it is still under heavy development. Details are on the developer's page and GitHub.
SurfacePsycho includes .step import and export as part of its surface design toolset in Blender. That lets you move .step files in and out of your Blender projects while working with the add-on's shapes. Because those shapes are stored as Geometry Nodes, the resulting blend files stay openable and shareable even without the add-on. The add-on is still under heavy development, so behaviour may vary between versions; the developer's page and GitHub repository cover the current documentation and status.
SurfacePsycho is listed here as free and is released under the GPL license. Because licensing terms can change, check the developer's page for the current details before you rely on them. The project also accepts donations through a donation portal linked by the developer. Since the add-on is under heavy development, keeping an eye on the developer's page and the GitHub repository is worthwhile for updates to its licensing and its feature set.
