LDraw models are meant for display usages, not manufacturing ones ?
So they contain many approximations that don't hinder their display usages, but are not precise enough to get good mechanical properties. For example pin holes are modeled as 16-sided prisms instead of true cylinders. That's enough to cause pin insertion problems!
