| Working Drawings | are detail or assembly drawing, containing the complete information for the construction of an object or the assembly of a product. Also referred as detail or assemble drawings, contains the complete info. for the construction of an object or the assembly of a product. Classified as shape, dimensions and specification. |
| Assembly Drawings | It is a drawing that contains the complete information for the construction of an object or the assembly of a product. |

| Orthographical Projections | a means of representing a three-dimensional object on a two dimensional drawing. It uses multiple views of the object, from points of view rotated about the object's center through increments of 90 degrees. Equivalently, the views may be considered to be obtained by rotating the object about its center through increments of 90 degrees. |
| Isometric Projections | Is a pictorial drawing that shows Front surface, side surface(s), top surface, height, Width, and depth of the drawing in a single view. |
| *1st Angle of projection | 12 |
| *3rd Angle of Projection | Mechanical drawing used to show true proportion without distortion along all dimensions. The three views are usually sufficient to describe the shape of an object. Most commonly used views are front, top and right side view. |
| Object Lines | 14 |
| *Hidden Lines | Hidden lines show holes or lines that you could not normally see from the view that you are looking at it. These lines are usually lighter and are dashed. |
| *Center Lines | 16 |
| *Phantom lines | 17 |
| *Cutting Planes | 18 |
| *Section lines | 19 |

| Surface | 25 |
| Scale | 26 |
| Viewing Size | refers to the size of the parts in a drawing compared to the size of the part. For example a house would have a reduced scale and watch parts would have an enlarged scale. |
| Drill | 28 |
| Ream | 29 |
| Boring | A way of producing holes that are round and concentric by means of a secondary operation using an straight fluted sizing tool. |
| Rounds | 31 |
| *Fillets | 32 |
| Chamfer | 33 |
| Undercut | cutting a recess in a diameter to permit two parts to join. When viewed on a drawing it is the looks like two square cut outs on each side of the part or shape. This operation can also be referred to as necking. |
| Taper | 35 |
| Knurl | 36 |
| Finish | 37 |
| Basic Fits | 38 |
| Nominal | 39 |
| *Tolerance | 40 |
| *Limits | 41 |
| *Bilateral | 42 |
| *Unilateral | Is a tolerance that is either a plus or a minus from the specified size, so the permissible variation in the opposite direction is zero. |
| *Allowance | 44 |
| RC Fit | Running and Sliding fits: These fits, for which tolerance and clearances are given in the appendix, represent a special type of clearance fit. These are intended to provide a similar running performance, with suitable lubrication allowance, throughout the range of sizes. |
| LC Fit | Locational Clearance fits: Locational clearance fits are intended for parts that are normally stationary but can be freely assembled or disabled. |
| LT Fit | Locational Transition fits: Locational transition fits are a compromise between clearance and interference fits, for application where accuracy of location is important, but either a small amount of clearance of interference is permissible. |
| LN Fit | Locational Interference fits: Locational interference fits are used where accuracy of location is of prime importance, and for parts requiring rigidity and alignment with no special requirements for bore pressure. |
| FN Fit | Force or Shrink fits: Force or shrink fits constitute a special type of interference fit. The interference varies almost directly with diameter, and the difference between its minimum and maximum values is small to maintain the resulting pressures within reasonable limits. |
| *Full section | 46 |
| *Half Section | A view that cuts a quarter of the section out so you can see the interior of the part. |

| *Datum | 58 |
| Rectangular | 59 |
| *Diameter Symbol | this symbol is used to dimension the outside to outside part of a round and should precede the dimension value. This symbol uses only one leader line to show the dimension. |
| *Radius Symbol | 61 |
| *Symmetrical lines | 62 |
| *Reference Dimension | 63 |
| *Machine symbol | 64 |
| *Finish symbol | 65 |
| *Do not machine symbol | 66 |
| *Reference Dimension | A dimension shown on a drawing for information only and it is not used for the manufacture of the part. This dimension is has parenthesis () around it. |
