i see the ones in the rcl lib and there is a 3d view for them and no it seems to be some blue rectangle thing i search these small beige disk caps
But the footprint is the same, isn't it?
I have never used the 3D view, I'm afraid. (Does Eagle 7.x even have one? I have never looked for it...)
Do you really need the 3D view? For drawing schematics and having PCBs manufactured, it is not required, and it does not matter at all if the parts look different in the 3D view than the ones yo will populate later. Unless you have very special needs (e.g. modellng something in detail in 3D, because you want to fit it ino a tight three-dimensional enclosure) I would just ignore the details of the 3D view.
