Handling of Dress-Up Pattern
When parsing the physical model, a simplification of the diagram is done when a dress-up pattern is detected. This pattern corresponds to a wireframe part that is connected to an isolated 3D shape with a rigid connection. The simplification consists in replacing the wireframe components in the diagram with the detected 3D shape component. As a result, the diagram of the generated model is more compact and it is easier to replace body components (to have flexible bodies for example).
