1. What is the primary difference between the Model tab and the Layout tab(s)?

1. the Model tab is used for drawing in 3D and a Layout is used for drawing in 2D

2. the Model tab is where you create the drawing and a Layout tab represents the sheet that you will plot or print on

3. the color of the background

4. the Model tab displays the drawing you are copying from and the Layout tab is where you lay out the new drawing
