Morphology
The meaning 'a measuring device for calculating board feet' is directly and transparently derived from combining 'board' (a piece of lumber) with 'rule' (a measuring tool). This noun+noun compound follows a common English pattern where the second noun names an instrument used with the first, so a B1 learner who knows both words would likely infer the meaning.
Etymology
Board rule may come from a simple shop tool: a flat board or metal strip with a measuring rule and numbers that let workers read sizes and get 'board feet' quickly. That's why the phrase means a measuring guide or standard for working out how much wood you have.
