3. Engineering Drawings
Defined as – technical drawings used to fully and clearly define requirements for engineered items.
- Not just a drawing, but also a language
- Drawings communicate all needed information from the designer to the worker who will make it

4. Engineering Drawings Items often included:
- Geometry - the shape of the object to be manufactured represented in different views
- Dimensions – the size of the object
- Tolerances – the allowable variations for each dimension
- Material – represents what the item is made of
- Finish – specifies the surface quality, functional or cosmetic

5. Engineering Drawings Title Block
The title block is an area of the drawing that conveys information about the drawing.
Items often included in a title block:
- Drawing Title
- Drawing Number
- Part numbers
- Name of Company
- Project Code
- Location
- Scale
- Units (inches, cm)
- Name of designer
- Name of Drafter
- DATE
- Signatures

6. Engineering Drawings Line styles and types
- visible lines – continuous lines used to depict visible edges.
-Heavy line for the outline
-Light line used for visible sections from the current view
Example
Drawing Example

7. Engineering Drawings Line styles and types
- hidden lines– short dashed lines that used to represent edges not visible from the current view
Example
Drawing Example

8. Engineering Drawings Line styles and types
- Center lines – alternating long and short dashed lines representing the axes of circular features
Example
Drawing Example

9. Engineering Drawings Line styles and types
- Cutting plane – medium to thick alternating long and short lines used to define sections
Example
Drawing Example

10. Engineering Drawings Line styles and types
- break lines – represent continuous sections of a design broken up to save room on the drawing
long break lines indicate a long break
short break lines indicate a short break
Example
Drawing Example

11. Engineering Drawings Line styles and types
- dimension lines- accompanied with measurements to define dimensions of the object
Example

12. Engineering Drawings Line styles and types
- Section lines – lines drawn to form a pattern to represent the interior section of a cutaway or the sliced section
Drawing Example
