How do I add a set I own?

Find the Set in the catalog and choose Add to My Sets (the set equivalent of adding a piece).

What happens

Adding a set creates your owned copy of it and automatically creates a Piece for each member model in the box — so your individual cars and engines show up in your collection too, already linked to the set. From there you can fill in condition, photos, and notes on each one just like any other piece.

Your new set tracks completion — how many of its members you actually have — which is handy if you're missing a car or two. See How does set completion work?

A few related situations:

• Own two of the same set? See Can I own more than one copy of the same set?
• Already logged the cars individually? See What are "loose pieces" and how do I promote them into a set?
