I was creating a scene and hid some components. How do I get them back?
Edit → Unhide
if you used the hide command (context menu e.g.) to hide them. If they are hidden with the layer functionality, make that layer visible again.
You can also check View menu>Hidden Geometry, and, then, if you now see your components, right-click on them and select “Unhide” from the context menu.
You can also install the unhide all plug in from this link:
