Again, I should READ

As the title states, I should READ. I am working through these new books for Unity3D and C#. I should have known what was happening because I have done this many times before. Working through one of the first chapters I ran into problems. When I was trying to place items on my terrain nothing was happening so, as I did before I stopped and spent hours trying to figure out the problem. Long story short, there was no problem. I decided to continue on and look at the errata for the book later to see if someone else had the same problem. The very next page the author states ‘nothing is showing’ and this is because etc. etc. and goes on to explain why and how you need to place this type of item.
Mike: Remember, READ and you may find the answer and avoid serious frustrations  .
