You are showing your version (beneath your avatar,) as: 8.0.4810 which is SU 8.0M1 Sketchup 8.0 was updated to M2, Released 12/1/2011, and has build number: 8.0.11751 on Mac. For specific information on the release, see the Release Notes page.

You have too many things in nests and components that contain components and loose geometry. The back panel for example is not a component but all that geometry is included with components in a nested component. Nested components have their place but what I saw in your model is something I frequently see in other beginner's models. It is easily repairable and we'll cover that when we talk.

Ken, if there's no unselected geometry attached to the selected stuff when you are making the component, the Replace Selection with Component box will be automatically checked. If, when you are making the component, that box is not checked automatically, it is your clue that you have unselected geometry attached. There are times when it is handing to select only part of the geometry you have drawn for making a component. An example in my work flow is crown moldings around cabinets. I'll often draw the crown around the three sides of the case using Follow Me and then, when I know I have the correct profile, I'll split it into components so it will be accurately represented in the cut list. For most parts however, I draw one the geometry for one component before I move on to the next part. I generally use a triple click of the Select tool on the geometry to ensure I get all of the attached geometry selected before I make a component. Making one component at a time in most cases is easier and there are fewer chances for errors.

So just think of the Scenes you create as photographs or snap shots of your model. Assign layers to the parts of your model including dimensions. Organize them so you can turn unwanted layers off for each snap shot. Move the camera as needed and adjust the layer visibility to show just what you want to see. Then create a scene. Change to the next and repeat.

Tick the SVG box in the main cutlist window and the SVG images will be saved to the same location as the model is saved. Then just open the images. If you use Firefox, I think there's a plugin to allow it to open SVG images. I think Safari will open them directly. You can also open them in Photoshop and many other image editors. I don't use the layout portion of CutList often but when I do, it is usually to share with someone else. For those, I convert them to PNGs so they are more easily viewed.
