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.

If the 2 diameters are the same and they are centered, they are contacting each other.
You can use coincident and select one of the spheres and a point on the surface of the other.
You could try tangent (pre-select the tangent constraint - don't use automatic)
For the datums, you can add the datums to a layer and hide that layer in the assembly. This works in Creo 3. Before creo 3 or maybe sometime during creo 2 development, layers would not work on set datums.

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.

Thank you . Your reply fix my question. I just need to go to the layers to make these hidden.

And then remember to "Save status"
Otherwise the next time you open Creo, the settings are reset to the latest saved status.

Yes. You're right.
