Are you trying to place an object in the model space, and it gives this message after doing so? In this case the whole message would be something along the lines of: "None of the created elements are visible in 3D View: <view name>. You may want to check the active view, its Parameters, and Visibility settings."
After resetting the visibility settings, as @seydauzun suggested, check the following:
- Do you have a Section Box activated? Placing an object outside it will also give this message.
- Is it a Central model? If that's the case, check also that the Workset you're using is open and active in the view.
- What is the Disciplane of the view? This can affect the visibility of certain objects.
Btw. don't just copy the existing 3D view or something - this will only give you the same view settings. Instead, create an entirely new one, by going View > 3D View > Default 3D view. If it doesn't create a new view, rename the old one.
