Let's say , I create a sphere and add an attr named "Test" (this attr is only used for find this sphere.). then , maybe some reference or import things. Now, I've many objects in my scene , but how can I select the just sphere I made before. Since the sphere name may changed by referencing , I guess it can be done by using the attr name "Test". But I don't know how.
Any and all helps and suggestions will be greatly appreciated!
