Meshing and export

Mesh From Implicit samples the implicit on a grid and extracts its surface. The most important input is MinFeatureSize: the voxel size of that grid, in model units. Set it smaller than the smallest detail you need to keep, such as the thinnest wall or strut.

• Each time you halve MinFeatureSize, the grid has eight times as many voxels, so start coarse and refine.
• BoundingBox limits meshing to part of the model. Leave it empty to mesh the whole implicit.
• Adaptivity (0 to 1) uses fewer, larger triangles in flat regions. Above about 0.3 the mesh mixes triangles and quads.
• Smoothing runs mean-curvature passes before meshing. It rounds the surface and softens creases, with slight shrinkage.

Mesh From Volume extracts the surface of a scalar volume at an Isovalue, normally 0. Its resolution is the voxel size the volume was created with, so set that on Scalar Volume From Field, Scalar Volume From Mesh or Scalar Volume From Points, or change it with Resample.

The panel 5. Remesh rebuilds a mesh's triangles without changing its shape:

• Remesh Sharp keeps sharp edges and grades triangle size by curvature. Use it for parts with sharp edges and crisp features.
• Remesh Smooth produces evenly sized triangles across the whole surface. Use it for organic shapes and smooth lattices.

Contour extracts the cross-section of an implicit on a plane as curves, without meshing. Use it for drawings, slice checks and toolpaths.

Meshes from Morphé are ordinary Rhino meshes. Bake them, or wire them into any Grasshopper component, and export from Rhino in the format you need: STL or 3MF for printing, OBJ for other tools.
