How to Change Modeling Settings in Google SketchUp 8
All you need to know about the controls in the Modeling section of the Styles dialog box in Google SketchUp is that there’s not much to know. Use the controls to adjust the color and visibility of all the elements of your model that aren’t geometry. To open these options, choose Window, Styles; click the Edit tab; and then click the box icon on the far right, at the top of the tab. The controls are described as follows:
Controls with color wells: Click the wells to change the color of that type of element.
Section Cut Width: This refers to the thickness of the lines, in pixels, that make up the section cut when you use a section plane.
Controls with check boxes: Use these to control the visibility of that type of element in your model. Three of them are a little confusing:
Color by Layer: Tells SketchUp to color your geometry according to the colors you’ve set up in the Layers dialog box.
Section Planes: This refers to the section plane objects that you use to cut sections. They’re gray with four arrows on their corners.
Section Cuts: Unlike section planes, this setting controls the visibility of the section cut effect itself. With this deselected, your section planes don’t appear to cut anything.
Match Photo settings: When you photo-match, adjusting the visibility of your photograph is sometimes helpful. Use these controls to hide, show, and adjust the photo’s opacity in both the background and the foreground.
