Used to describe an action that has just been completed, often followed by a result or observation.
Long explanation:
The ~たところ grammar point is used when an action has just been completed and the speaker wants to describe an observation or result that follows from it. It can be translated as 'just finished doing something' or 'just did something'. The formation is the same for all conjugatable words, which include verbs, い-adjectives, な-adjectives, and nouns.
