Term: altBuild
Definition:

A boolean property indicating whether a MOC (My Own Creation) is an "Alternative Build," meaning it was designed using exclusively the parts available in a specific official commercial set. This distinguishes it from "original" MOCs that may use a custom selection of loose parts.

Examples:

True for a spaceship model built using only the pieces from the LEGO 31107 Space Rover Explorer set.

False for a custom building that requires parts from multiple different sets or individual brick purchases.
