- How do I identify a Lego part? 1 answer
I've found http://rebrickable.com/myparts linked in one of the answers here on this site and I'd like to list all of the parts I have at home (probably a thousand or two). The problem is, there is a lot of similar pieces on Rebrickable, including some which have "similar" in the thumbnail image, or have three zeros for parts, sets and colors.
For example there is a 1x2 brick with no hole in it: 3004. What is the difference between this and 3004px3? Can I filter the useless bricks out? How can I find the version with circular hole in the middle used a lot in Technic?
But the whole question boils down to: How to efficiently identify bricks and their names?
