An old method of reproducing drawings that wound up with the copies being blue background with the lines in white. The original drawing was fed through rollers with the blank paper that exposed it to light. Then the blank paper was devleoped by exposing it amonia---very smelly process. The paper would develope into a blue color and the exposed lines were white---usually.

Who can help me draw a blueprint for a project?
A "blueprint" is an old way of copying an original drawing onto blueprint paper. UV light is used to expose the blueprint paper, and ammonia is used to develop the image. Sometimes the term, "Blueprint" is a way to say, "construction drawings", which may include plan views, elevation views, cross sections, profiles, or details. They are drawn by drafters, engineers, architect, or anyone with the knowledge and a CAD program or (shudder) pen or pencil on paper, linen or polyester film.
What is the difference between a general and specific tolerance and how can you tell the difference on the drawing?
when reading a blueprint, a general tolerance would apply for all dimensions that are not individually identified. eg, all tolerances are +\- .030" General tolerances are normally found in the information blocks of the blueprint. If for example a tighter tolerance is required, then a specific tolerance is noted for certain areas of the blueprint. These tolerances are normally found beside the affected area.
