But in quick3D that would be done with a class derived from QQuick3DGeometry with primitives set to lines "setPrimitiveType(QQuick3DGeometry::PrimitiveType::Lines)" to construct a cube. Then register that class to qml and use it in your View3D. Hope it helps.
Any alternative to QQuick3DGeometry as I'm using 5.10?
