BullAnt is a Rhino3d/Grasshopper plug-in primarily for Architects and Engineers (but also other Rhino/Grasshopper users) featuring computational design tools to enhance and extend Rhino/Grasshopper.  BullAnt features commands including mesh relaxation (minimal surfaces), mesh inflation (ETFE cushions), symmetry automation, tessellation (polygon packing), geodesic domes and curve network processing.  Much of the structural sketching functionality is now deprecated and available in ggRhinoIFC plugin.

FractureHopper is an extension of GH for fractal math and chaos theory. It extens grasshopper with a number of utilities: Julia 2D and 3D sets and tests, Lorenz attractors, Rabinovich-Fabrikant maps, Bifurcation diagrams.

This toolkit focuses on the versatile nature of meshes, providing various effective functionalities for working with and editing mesh topology. Heavily inspired and driven by the concept of edge loops (thank you, Autodesk Maya and Pixologic ZBrush), the organizational data structure behind mesh construction provides a plethora of design possibilities, some of which are still being discovered today.

Rabbit is an open-source plug-in for McNeel’s Grasshopper that simulates biological and physical processes.

Generate Minimal Surfaces from boundary curves or do a minimal relaxation on a mesh.

Wasp is a Grasshopper plug-in, developed in Python, offering combinatorial tools to design with discrete elements. The description of each part includes all information necessary for the aggregation process (part geometry, connections location and orientation). The connections define the topological graph of the part, which is used to define the possibilities of aggregation with other parts. Wasp offers a series of aggregation procedures, allowing geometry- and data-driven generation of structures. Additionally, it provides tools for constraining the resulting aggregation, both at the local and global level, as well as utilities to visualize and process it.

Just an usual mesh pipe and mesh sweep. Find both in Mesh->Primitive panel.

FlexHopper offers very fast, particle-based physics simulation within Grasshopper. It let’s you simulate unconstraint particles, fluids, rigid and soft bodies, textile and spring system, inflatables and a combination of all these materials in one scene at unparalleled speed. You can add collision geometry, define custom constraints and emit new particles during runtime.

This is an outcome from a research in Computaional Design. Althought it is not that completed, you could enjoy it.

Droid is a 3D printing related Grasshopper Plug-in Library add-on, with control over model Slicing, Custom paths and Gcode generation.

A DISCRETE ASSEMBLY TOOLKIT FOR ARCHITECTS AND DESIGNERS Monoceros is a legendary animal living in the huge mountains in the interior of India. Monoceros has the body of a horse, the head of a stag, the feet of an elephant and the tail of a boar.

3D Graphic Statics is a structural form-finding method for generating compression-only funicular structures.

EleFront v4.3.0 is the Rhino 6 legacy release.  Component names and icons have been changed to make it easy to distinguish from the new version. Only install if you want to have the stable version and the beta installed side by side. If you are not testing the beta and only work in Rhino 6, install version 4.2.2 instead.  Version 4.3.0 works in Rhino 7 as well, but does not implement any of the new features that are present in Rhino 7 only.

Curve plus is a collection of curve modifier components developed over several years and wrapped up in this little library. The components range from simply exposing Rhinocommon curve commands, like spirals and control point weighting, to new tools like blending corners and a range of radial spirals. These components integrate into existing Grasshopper Curve, Vector, and Mesh tabs.

Zebra is a C# grasshopper plugin, developed by YFA team when a need came for an agent based design plugin

XOLOTL provides a set of components for volumetric modeling in Rhino Grasshopper. They work based on the principle of signed distance functions (SDF). In boundary representations (BRep), objects are defined by vertices connected by edges and faces. In function representations (FRep), objects are defined by a function f that maps any point (x,y,z) to a real value d, the distance to the objects: f(x,y,z)=d

Weaverbird is a topological modeler that contains many of the known subdivision and transformation operators, readily usable by designers. Instead of doing the work repeatedly, or sometimes using complicated scripts, this plug-in reconstructs the shape, subdivides any mesh, even made by polylines, and helps preparing for fabrication.
