    Class OCCTAssembly

    Assemblies as OpenCascade documents: a document holds parts, the sub-assemblies that group them and the instances that place them, with names, colors and placements, the way a STEP assembly does. manager builds documents step by step from parts and nodes, loads STEP files into them, changes labels and exports to STEP and glTF; query reads parts, shapes, colors, placements and the hierarchy back out. Every label in a document is addressed by its label id string. A document stays in memory until it is deleted.

    const box = await bitbybit.occt.shapes.solid.createBox({ width: 10, length: 10, height: 10, center: [0, 0, 0] });
    const part = await bitbybit.occt.assembly.manager.createPart({ id: "box", shape: box, name: "Box" });
    const root = await bitbybit.occt.assembly.manager.createAssemblyNode({ id: "root", name: "Root" });
    const instance = await bitbybit.occt.assembly.manager.createInstanceNode({ id: "box1", partId: "box", name: "Box 1", parentId: "root" });
    const structure = await bitbybit.occt.assembly.manager.combineStructure({ parts: [part], nodes: [root, instance], clearDocument: false });
    const doc = await bitbybit.occt.assembly.manager.buildAssemblyDocument({ structure });
    const parts = await bitbybit.occt.assembly.query.getDocumentParts({ document: doc });
    const glb = await bitbybit.occt.assembly.manager.exportDocumentToGltf({ document: doc, meshDeflection: 0.1, meshAngle: 0.5, internalVerticesMode: false, controlSurfaceDeflection: false, mergeFaces: false, forceUVExport: false, fileName: "assembly.glb", tryDownload: false });
    await bitbybit.occt.assembly.manager.deleteDocument({ document: doc });
