1. Blueprint A design plan or other technical drawing.
synonyms: plan, design, diagram, drawing, sketch, map, layout, representation
2. Title block The box located in the lower right corner of the drawing that contains general
information about the part in the drawing. Such as company name, drawing
number, part number, and other pertinent information.
3. Tolerance "Allowance for a specific variation in the size and geometry of a part."
4. Object line It is a solid line that outlines the shape or size of a part.
5. Hidden line It is standard practice to use dashes to represent any line of an object that is hidden
from view.
6. Center line Long and short dash lines. Usually indicates the center of holes, circles, and arcs.
The line is thin and dark.
7. Section line Medium lines drawn at 45 degrees use to show the interior view of solid areas of
cutting plane line.
8. Extension line Thin and dark line use to show the starting and ending of dimension.
9. cutting plane line An extra thick line used to show cutaway views or plane of projection where a
section view is taken. Arrow indicates the direction of view.
10. Dimension Line Thin and dark lines use to show the size (span) of an object with a numeric value.
Usually, terminates with arrowheads or tick markings.
11. Break lines Break lines are used to show a break in a drawing and are used when it is desired
to increase the scale of a drawing of uniform cross-section while showing the true
size by dimension lines.
12. Short break lines Short break lines are usually heavy, wavy, semi-parallel lines cutting off the object
outline across a uniform section.

13. Long break lines Long break lines are long dash parallel lines with each long dash in the line
connected to the next by a "2" or sharp wave line.
14. Orthographic a two-dimensional drawing of a three-dimensional object, using two or more
View additional drawings to show additional views of the object.
15. Isometric View is a method for visually representing three-dimensional objects in two dimensions
in technical and engineering drawings.
16. Nominal size The size used for general description.
17. legend A list that identifies patterns, symbols, or colors used in a chart
18. Scale Specify a percentage of original size to enlarge or reduce the size of an object.
19. Tolerances or a range of acceptable values established by engineering design or customer
specifications requirements
20. border line heavy black line drawn close to the outer edge of paper used for drawing plans
21. framing plan diagram showing the arrangement and sizes of the structural members in a floor
or roof
22. Revision Block A brief listing of revisions made to a drawing since it was initially released to
manufacture.
23. Cross Section a diagram that shows what the inside of something looks like
24. Materials List A list of all the materials and the amounts of each material necessary to carry out
the experiment
25. Elevation View the finished exterior appearance of a given side of a house
26. plan view A drawing that represents a view looking down on an object.
