Official Part

From LDraw.org Wiki

An official part is an LDraw part file which has passed the Parts Tracker certification process during which it gets quality checked by

  • at least 2 part authors
  • the parts tracker Admin.

On regular intervals, LDraw.org releases newly certified official parts. They can be found at

You can either download just the newly added/corrected files, or the complete set of all official parts together (complete.zip).

All other LDraw part files which have not passed this certification process are called unofficial parts.
