I know this has been asked but nothing recent seems to address the question. How do I delete components from the components list in the web? In the screen shot below I have no option to purge components and I have no way to select and delete one. It says one of them, Front Leg1, is in use and it’s not. This seems like it should be a very simple straightforward action.
You can only purge unused components. If you scroll to the bottom of the components list you should see unused components and the Purge button (recycle symbol)
The component you show highlighted must be used in the model somewhere or it would be at the bottom of the Components list, not at the top. Before you can purge it from the list you need to delete all instances of it from the model space.
you have to delete from the model itself, select a component and press delete from the keyboard. then you will see it under the unused components.
And if you have a Go, Pro, or Studio subscription, SketchUp for Web also has the Outliner, which allows you to select a Component (and any multiple instances of a Component) and delete from the drop-down menu. In my video, I hold Shift and click and select multiple components to delete.
