(background of the problem)
I ran into a problem yesterday filming my character from a long way off outside of a window. The Opacity of this hat looks really bad from far away:

If I move the camera to inside the window, the issue is fixed:

So if you happen to know a way I can solve the above issue, I don't have to create my 'Distraction' prop that I look at from outside the window and then switch to the "teacher".
I was trying to think of what distraction prop to create, and I walked by a furniture store with a hanging mobile (I had to look up the term because I couldn't remember last night):
I searched the marketplace for mobiles because I will always buy before I create unless I have more time than money, which is rare these days.
I didn't find any so I searched Google Images and found this and it looks pretty easy to make, except the little arch hangers I wasn't sure how to create that after looking at the arcs in IClone.

The spheres look easy to create and change textures, and the string could just be a very narrow cylinder, but the wood or bamboo or whatever texture that is for the arches I didn't know how to create.
I wish there a 3D eraser tool. Where I can take a model I want, and erase away the parts I don't want. Does anything like that exist (anywhere, not just IClone)?
Thanks, and sorry to post a bunch of questions in one thread, but it easier for me to follow one thread than multiples.
