Great tutorial! I am new to Cinema 4D and am learning from Getting Started with Cinema 4D. I am in chapter 6. and I have three questions:

1. The perspective window, the grid is in the wrong direction; how can I adjust the grid?
2. I can't scale or rotate the crab. The center of the scale icon is not activated. It's gray. How can I fix the issue?
3. I copied and pasted all the parts into a new document. Now, when I scale the crab, all the parts scale up individually, and you lose all the proportions. in the image, the pupils disappears. How can I fix the issue?
