Changing Scenes

• What is Meridian Tapping and How Can It Help

Why do I see a warning box when I create a new scene?

Occasionally when you create a scene, an ominous warning pops up, demanding attention before you can go on (Figure 12-3). Here's what's going on: SketchUp keeps track of the Styles you're using. When you choose a style and then make changes to the style, SketchUp takes note. The change could be something like turning on shadows or hiding guides. When you create a scene, SketchUp remembers the style used in the scene. However, if you made changes to the style but haven't saved those changes, SketchUp gets confused. Later when you show this scene, do you want to see the original style? Do you want to see the changed style? Usually you want to see what you're viewing at the moment in the modeling window, and that's the changed style. The problem is SketchUp can't show you what you see in the modeling window unless you save the style and its changes. So it gives you a few choices via radio button:

• Save as a new style. Choose this option when you want the scene to show the style with changes. SketchUp automatically creates a new style to match what you see in the modeling window.

• Update the selected style. This option also saves the view that you see in the modeling window. The difference is that it saves the style changes to the original style. That means any other scenes that use that style will look different, too.

• Do nothing to save changes. If you choose this option, the scene won't match what you see in the modeling window. SketchUp doesn't create a new style and doesn't change the existing style.

At the bottom of the warning box is a checkbox where you can tell SketchUp "Quit bugging me with this annoying question." That's not exactly what the label says, but that's what it means. Turning on this box is the same as always choosing the "Do nothing to save changes" option. In this case, you're responsible for remembering when you've made changes to styles and making sure that the scenes are saved with the look that you want.
