Mesh boundary

Creates polyline curves around all mesh boundaries.

Inputs

• geometry

  • Accepts a single geometry connection (unless the SHIFT key is held).

Outputs

• geometry

  • Output primitives.

• points

  • The list of points of the output primitives.

• points.x

  • The list of x values of the points of the output primitives.

• points.y

  • The list of y values of the points of the output primitives.

• points.z

  • The list of z values of the points of the output primitives.

• boundary mask

  • The list of boolean values identifying if a vertex was used to create a curve or not.

• boundary indices

  • The list of indices of the vertexes that define the resulting boundary.

Note(s)

• An example of an instance where a mesh boundary will not be made (and therefore will turn a false result in the boolean mask output) might be where mesh edges/boundaries are welded together (and thus not a boundary) or, a primitive type other than a PolyMesh is input into this node.

• Other names for this node include: MeshBoundary, Edges, Contour, and Border.

Example(s)

• Polyline box

• Loft along curve w/ cap

• Isolate face holes and boundary
