    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, glTF and OBJ files into them, changes labels and exports to STEP, glTF, OBJ and PLY; query reads parts, shapes, colors, placements, the hierarchy and the dimensions and tolerances 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 });
