I hid a component, now it won’t unhide in Sketchup Pro 2019.
Does it show up in Outliner? Are you sure you didn’t erase it accidentally? Did you assign a layer/tag to it and turn off the visibility of that tag? Did you hide the geometry within the component instead of hiding the component? Do you see a mesh where it should be when you turn on Hidden Geometry in the View menu?
Share the .skp file with us and we won’t need to play 20 questions. Also please give your thread a useful title instead of using your name.
Thank you! I got it to show in light outlines. Then I was able to get it to unhide.
