Morphology
The compound combines 'snap' (a sudden sharp action) and 'line' (a mark), so a B1 learner who knows both words can infer this refers to a line produced by snapping (i.e. the chalked string that is snapped to mark a straight line). The term names the action and resulting mark in a literal, mechanical way, making the meaning directly derivable from its parts.
Etymology
Snap line comes from a simple tool: a chalk-covered string that you stretch tight and snap so the chalk hits the surface and leaves a straight line. So a snap line is the string used 'to mark a straight line' when building or fitting things.
