During the reading of a blueprint, a general tolerance pertains to all dimensions that are not independently identified. All tolerances are + / -.030. General tolerances are mostly found in the blueprint’s set of information. Let’s say for example, a compact tolerance is required, then a specific tolerance is considered for specific areas of the blueprint. These kinds of tolerances are commonly found along the affected area.
