Hello Alex!
Ldraw files are made of text lines.
Typically, in model files (that contain parts), lines begin with numbers
lower than 2
0: comment
1: part (position and orientation)
Typically, in part files (that contain primitives), lines begin with numbers
from 2 to 5
2: line (2 points)
3: triangle (3 points)
4: quad (4 points)
Of course most parts also contain line(s) 1 as subpart(s) because of either
complexity or standardization.
Read http://www.ldraw.org/reference/specs/fileformat for more info about
line format.
Happy programming,
Damien
