Interface AssemblyStructureDef<T>

All part definitions (shapes that can be instanced)

All nodes (assemblies and instances)

Labels to remove from existing document. Can be part labels, instance labels, or assembly labels. Ignored when creating a new document.

Updates to apply to existing parts in the document. Each update can change the shape, name, and/or color of a part. Ignored when creating a new document.

Each entry copies a label tree from a source document into this document, preserving sub-assembly hierarchy, names and colors. The copied root then behaves as a regular part: instance nodes can reference it by partId and place it multiple times with different transforms.

Whether to clear the existing document before adding new content. Only relevant when an existingDocument is provided.

• true: Clear all existing shapes, then add new parts/nodes (full rebuild)
• false: Keep existing shapes, apply removals/updates, add new parts/nodes (incremental)
