How do you unhide hidden groups in SketchUp?

You can unhide hidden groups in SketchUp using the View menu or the Outliner.

Here's how to unhide hidden groups in SketchUp:

Method 1: Using the View Menu (Hidden Geometry)

1. Navigate to the View Menu: In the SketchUp top menu, click on "View".
2. Enable Hidden Geometry: Select "Hidden Geometry". This will make any hidden entities (including groups) visible in a lighter, dashed style.
3. Select the Hidden Group: Click on the group you want to unhide.
4. Unhide the Group: Right-click on the selected group.
5. Choose "Unhide": Select "Unhide" from the context menu. This will make the group permanently visible.
6. Toggle Hidden Geometry (Optional): If you want to hide the dashed display of all hidden geometry again, return to the "View" menu and deselect "Hidden Geometry".

Method 2: Using the Outliner

1. Open the Outliner: The Outliner is typically part of a tray window. If you don't see it, go to "Window" -> "Default Tray" and make sure "Outliner" is checked. If you use a custom tray, look in "Window" -> "Trays".
2. Locate the Hidden Group: In the Outliner, you'll see a hierarchical list of all entities in your model. Hidden groups will often be displayed grayed out or with a different icon that indicates their hidden status.
3. Unhide the Group: Right-click on the group's name in the Outliner.
4. Choose "Unhide": Select "Unhide" from the context menu.

In summary, SketchUp provides two straightforward methods to unhide groups: enabling "Hidden Geometry" through the View menu to visually select and unhide them, or utilizing the Outliner for a direct, hierarchical approach to managing entity visibility.
