5. Group It

Using a group is extremely beneficial if you have to make changes to your model later in time. Organizing parts of the model into groups allows you to alter one part of your model without affecting the faces and lines attached to it. Click on the surfaces/lines/figures right-click>create a group. Double-click the group to easily edit it.

6. 层——但不要太多

使用图层来顺利地进行工作 。 如果您要将其他模型或cad文件导入到SketchUp中 ， 可能会有无数新层形成 ， 如果您删除任何一层 ， 请小心它们可能来自cad文件或其他模型 。 隐藏未使用的层(windows>Layers)能有效地隐藏当前未使用的模型部分 。

6. Layers – but not too many

Use layers to perform work smoothly. If you are importing other models or CAD files into SketchUp there might be innumerable new layers added from them. If you choose to delete any layers be careful – they might be from the CAD file or other models. Hide the layers you are not using (Windows>Layers) to hide the parts of the model you are not currently using.
