I've got a family table part model with the generic and one instance. I created a layer in the generic called GTOL_DTMS and I put the declared datums A, B, C & D on it and changed the display to HIDE so I don't have to see the datums while working on the shaded model. We do this for all models. However, when I open the instance of this model, the declared datums are visible and the instance does not have the layer GTOL_DTMS. I thought layers always propagated from generic to instances. I've tried using the model player to regenerate from the start, no luck.
