Getting rid of edits you made to a component?

Hi there,
very, very new to sketch up here. I have made an indent in a component that I would like to get rid of (see below)

so that the top is one smooth piece again. how might I do this?

Assuming it’s too late to just use Undo, the easiest would be to open the component for editing and use Push/Pull to pull one side over to the other. Then erase any remaining unnecessary edges.

Thanks very much :wink:
