To start, I would like to thank everyone who replied to "An easier way to do this" a post by Carcharodon. I also read "welding "Groups" together" by Curtis.
Both these post caused me to go back and review the part of "Google Sketchup for Dummies" book, which covers the use of Outline, Compoments and Groups. After reviewing those sections, I feel that I was correct (as I outlined my use of Layers) in the easier way post.
But, reviewing the book renewed expanded my knowledge of Layers and such. One point is the use of components in modeling. Also, Using the knowledge gained by reading "Welding "Groups"...I now plan to make more use of components. Thank all of you again, because people do read these post and good thinks come from it.
Question: I have a model that is all ready in progress that has several parts that could have been components. I could make one of these parts into a component. Once the "component" is created, do I have to delet the other excesting part and replace then with an "Instances" of the new component or is there and easier way of doing it? Thanks for your help, Bob
