Brick Parts Names: Full List With Numbers and Diagrams
What is the hardest thing about reading a MOC instruction? It is not the structure — it is the string of terms you cannot put a name to. "2x4 brick," "1x2 plate," "1x1 slope": if you cannot decode them, you end up guessing part by part. Learning brick parts names is the first lesson in building, and the basis for finding parts, buying parts and following someone else's plan. Below we walk through five families: bricks, plates, slopes, Technic and minifigures.
This is the most complete brick parts names list we have assembled, covering the classification, names, numbers and uses of every common part. Newcomers and veteran builders alike should keep it on the desk as reference. Every MOC instruction on brickplan.cn uses standard part names, so knowing these terms lets you read any plan without effort.
