Automatic mesher for thin-shell structures in Rhino
With click of a button you get nicely meshed and properly connected thin structures, ready for FEM analysis.

Features
- Optimal triangular meshing of surfaces, better than Rhino's algorithms
- Uniform size remeshing of meshes
- Automatic stitching of gaps between edges of surfaces and meshes
- Resolving intersections and stitching that allows gaps between perpendicular surfaces
- Automatic resolving of complex intersections between meshes
- Optimization and simplification of non-manifold edges after resolution of intersections
- Automatic cleaning of small parts (e.g. artifacts after intersection)
- Automatic cleaning of defective triangles
Future features
- Adaptive-size meshing and remeshing
- Optimization of triangles quality
- Re-checking if holes occured to be filled
- Interactive remeshing of specific parts
- Quadragulation to obtain pure-quad or quad-dominant meshes
Installation
Option 1: In Rhino 8, under Tools > Package manager search for Meshell and click Install.
Option 2: Download as installable plug-in from Food4Rhino.
Usage
Automatic meshing
Enter MeshellAuto into the command line to merge surfaces within some tolerance and prepare the full mesh. Command options:
- Remesh = whether to use uniform remeshing techniques (On), or use default Rhino meshing techniques (Off)
- BaseSize = how large should cells be
- GapsTol = maximum tolerance for stitching gaps between objects
Explode the mesh into manifolds
Enter MeshellManifolds into the command line to explode the selected mesh into separate manifold meshes.
Remesh full mesh
[Coming in v0.5] Enter MeshellRemesh into the command line to re-mesh a mesh into elements of different size.
Remesh selected mesh part
[Coming in v0.5] Enter MeshellRemeshPart into the command line to re-mesh a specific part of the mesh into elements of different size.
Quadragulate the mesh
[Coming in v0.6] Enter MeshellQuadragulate into the command line to convert the mesh into a quad-dominant mesh
