Constrains question in assembly and the unnecessary shown of the datum plane

I want to add constraints, can be contact or distance,  in assembly using two sphere surface, (both surface with same DIA). But looks like  it does not work, please see picture. Any one can help?

One more question is , in the same assembly. There are some datum plane showing on the screen. They are from the component level when I worked on the detail drawing. Can I make these datum no-shown in assembly model or even in component as well?

Thanks.

For the assembly constraint, preselect the CENTERED constraint before selecting the spherical surfaces.

Actually, I want to make these two sphere surface contact each other.

You can use point on point (the center of the spheres)

You can try [Tangent]

Regarding showing datum planes:

You can hide them using Hide planes

You can place all datums with rules on layers.

Then using Layer Tree you can hide them on part, drawing or assy level.

    For datum planes, if you link them to a tolerance box, they do not appears in assembly. But sometimes they appears in the drawing and you have to "erase" them.

    I defined the datum plane in drawing. And I do not really need them shown in 3D, but these planes do show in the component level then shown in the assembly. I erased them in part but the other day I open the file, they show up again.

    Yes. You're right.
