public Mesh BooleanUnion(Mesh tool)

Returns a new mesh unifying the tool mesh and the original mesh.

public BoundingBox BoundingBox()

public Mesh CloseCracks()

Removes internal boundaries of a Mesh. An internal boundary occurs when there are coincident vertices, such as if Mesh had separate triangle groups for the lid of a pot and the body of the pot.

public Line[] Edges()

Converts the Mesh edges to Lines, and returns them

public Mesh[] Explode()

Converts Mesh triangles to individual meshes and returns them.

public Mesh GenerateSupport(double baseHeight = 0.4, double baseDiameter = 8, double postDiameter = 3, double tipHeight = 1, double tipDiameter = 0.5)

Returns a new Mesh with support structure. Default threshold settings are used if input is empty.

public PolyCurve[] Intersect(Plane intersectionPlane)

Intersects input Plane with the Mesh, producing a PolyCurve

public Mesh MakeHollow(int holeCount = 1, double holeRadius = 1.5, double wallThickness = 2, double solidResolution = 128, double meshResolution = 128)

Returns a new Mesh that has been hollowed out for 3D printing.

public Mesh MakeWatertight()

Returns a new Mesh that is watertight and 3D printable. As a result of making a Mesh watertight, self-intersections, overlaps, and non-manifold geometry is removed from the mesh. The method computes a thin-band distance field and generates a new Mesh using marching cubes but doesn't project back onto the original Mesh. Basically the Mesh is filled with a bunch of tiny boxes, and a new mesh is created around this.

public Mesh Mirror(Plane mirrorPlane)

Reflect the Mesh across the input Plane

public Point Nearest(Point point)

Nearest point on the Mesh to the specified point

public Mesh PlaneCut(Plane plane, bool makeSolid = false)

Create a precise geometric planar cut which removes portions of the mesh that lie on the side of the plane in the direction of the plane normal.

public Point Project(Point point, Vector dir)

Projects point onto the Mesh along the specified direction

public Mesh Reduce(double triangleCount)

Returns a new Mesh with a reduced number of triangles.

public Mesh Remesh()

Returns a new Mesh distributing triangles more evenly over the whole of the selection regardless of any change in triangle normals across the given selection.

public Mesh Repair()

Returns a new Mesh with the following defects repaired: Small components: if the Mesh contains a very small, disconnected segments, relative to the overall Mesh size, they will be discarded. Holes: holes in the mesh are filled in Non-manifold regions: if a vertex is connected to more than two *boundary* edges, or an edge is connected to more than two triangles then the vertex / edge is non-manifold. The mesh toolkit will remove geometry until the mesh is manifold This method tries to preserve as much of the original mesh as possible, as opposed to MakeWatertight, which resamples the Mesh

public Mesh Rotate(Vector axis, double degrees = 0)

Rotate the Mesh around the input axis by input degrees. Rotation is centered at the origin

public Mesh Scale(double scaleFactor = 1)

Scale the Mesh by the input amount

public Mesh Scale(double x = 1, double y = 1, double z = 1)

Scale Mesh non-uniformally by scale factors

public Mesh Smooth(double scale = 4)

Returns a new smooth Mesh. Smoothing type by default is cotangent which smooths without spreading the vertices.

public string ToJson()

Convert the Mesh into a JSON object formatted with dynamo.geometry:mesh-1.0.0 schema.

public Mesh Translate(Vector vector)

Translate a Mesh in the direction of input Vector by the length of the Vector

public Mesh Translate(Vector vector, double distance = 0)

Translate the Mesh in the direction of the input Vector by the input distance

public Mesh Translate(double x = 0, double y = 0, double z = 0)

Translates the Mesh by the input distances

public Point[] TriangleCentroids()

Returns Triangle Centroids

public Vector[] TriangleNormals()

Returns the normals for each triangle face in a given mesh.

public Surface[] Triangles()

Converts the Mesh faces to Surface patches, and returns them. Note: this method can generate A LOT of heavy Surfaces, and may slow down Dynamo with large meshes.

public List<int> VertexIndicesByTri()

Returns the vertex indices for each mesh triangle. (as opposed to unique vertex indices)
