Click View tab > Visibility panel > Blanking > Blank Selected to temporarily hide the selected model components from the screen. Blanked model components are not deleted, but hidden. You can unblank them when required. This enables you to concentrate on the part of the model you want to work on without being hindered by other areas of the model.
You can use this when using a Level is not appropriate. This may be because a level may contain components you don’t want to be hidden or changing the levels may affect the model’s logical structure.
For more information see Example of using Blanking.
