Blueprints

3. Points from the reference line to the specific joint or area to be welded.
5. key that explains the meaning of the various symbols and abbreviations used in a specific set of drawings
7. The ratio used to represent the building or object accurately on paper
9. A standard section on every drawing sheet containing essential project information, such as the project name, date, designer, and drawing number.
10. thin, solid lines with arrowheads at both ends. They show the distance or measurement between two points, with the actual measurement value typically placed above or within the line.
12. medium-weight lines made of short dashes. They indicate edges, surfaces, or components that are not visible in the current view
13. thin lines with a pattern of alternating long and short dashes. They mark the exact geometric center of symmetrical objects like circular features, holes, or axes of rotation.

1. The horizontal line that serves as the anchor for all weld symbols and dimensional information.
2. These lines show that a part of an object has been omitted or shortened to save space on the drawing.
4. These are thick, continuous lines used to define the visible edges, outlines, and boundaries of the main object
6. section at the opposite end of the reference line used for supplementary information, such as the specific welding process
8. A geometric shape placed on the reference line that indicates the type of weld required
11. numerical value indicating a specific measurement (length, width, height, etc.).
