TraverseAllSystems

C# .NET Revit API add-in to extract graph structure of all MEP systems.

For more information, please refer to The Building Coder discussion on traversing and exporting all MEP system graphs.

Options

Use element id or UniqueId for to identify node
Store JSON graph bottom-up or top-down

The two bottom-up and top-down JSON storage structures both comply with the jsTree JSON spec.

Bottom-Up JSON Structure

[
  { "id" : "ajson1", "parent" : "#", "text" : "Simple root node" },
  { "id" : "ajson2", "parent" : "#", "text" : "Root node 2" },
  { "id" : "ajson3", "parent" : "ajson2", "text" : "Child 1" },
  { "id" : "ajson4", "parent" : "ajson2", "text" : "Child 2" },
]

Top-Down JSON Structure

      name: 'Child 0_1',
      type: 'window',
      otherField: 'something...',
      children: [
      {
        id: 0_1_1,
        name: 'Grandchild 0_1_1'
      }]
    }, {
