Now let's take a step toward how to actually use groups for architects and interior designers. Remember, groups are unintelligent containers that have no connection between copies. Groups simply isolate entities to make it easier to work on pieces of a model, rather than tediously picking through one big blob of sticky geometry.
We need to group our model into useful categories that will make it easier to work on. For this demonstration we will create groups based on shape, color, and size.
First, we need to separate like shapes into their corresponding group. There will be one group containing cubes, one for spheres, and one for pyramids.
Next, we need to further organize the shapes by color. Within each shape group there will be three more groups, one for red, one for gray, and one for white.
Finally, we need to further organize the shapes and colors by size. Within each of the three color groups held within each of the shape groups, there will be two more groups, one for small, and one for large.
The Outliner sheds some light on model organization by displaying a file tree type diagram of your model. Open it by clicking on the Window dropdown > Default Tray > Outliner. Keep these tips in mind...
Once your model organization is in place, you will inevitably need to move objects and geometry from the base level of SketchUp into a group, or even from one group to another. You can move entities within your model organization using the "Cut" and "Paste in Place" commands. The advantage of "Paste in Place", compared to "Paste", is that it drops the clipboard contents back into your model at the exact same coordinates. Follow these steps...
