| Question | Answer |
|---|---|
| Used to create technical drawings and sketches. | Technical Pencils and Pens |
| Technical Drawings | Hard to Soft Pens |
| Graphic Arts | Black to Light Pens |
| Not hard/soft, not black/light | Fine |
| For technical drawings and graphic arts | HB |
| is used as guide in drawing horizontal lines | T-square |
| provide drafters with angles commonly used in technical drawing- 30, 45, 60 and 90 degrees | Triangles |
| needed for measuring sizes and distances, and for transferring measurements from it to the drawing paper | Scale or Rule |
| tool used to measure or lay-out an angle or an arc | Protractor |
| drafting tool used as guide in mechanically drawing irregular curved lines | French Curve |
| Necessary when erasing inked or penciled lines, views, and so forth, located in areas where there are other lines | Erasing shield |
| Necessary when erasing inked or penciled lines, views, and so forth | Drafting eraser |
| Used to draw large arcs and circles | Drawing compass |
| Types of templates available | Circles, ellipses |
| Drawing template's measurements | 10mm 100mm 100mm 90mm 20mm 6mm (2mm up and down) 6mm (7mm up and down) |
| - The act of placing handwriting on a technical drawing. - Writing of titles, dimensions, notes and other important particular on a drawing | Lettering |
| IMPORTANCE - Gives pertinent information - Records ideas and help transmit these ideas - No matter how nice the drawing is, if the letterings are poor, the entire drawing will be spoiled | Lettering |
| Style of Letters | 1. Single stroke gothic lettering style 2. Roman Letters 3. Italic letters 4. Text Letters |
| formed with a series of single strokes that are wide as the pencil point or drawing pen | Single stroke gothic lettering style |
| – all letters having “accented” stroke or consisting of heavy and light or thick and thin lines | Roman Letters |
| – all slanting letters are classified as Italics | Italic Letters |
| these includes all styles of old English, German text, Bradley text or other various trade names | Text letters |
| Proportion of letters | 1. Normal letters 2. Compressed letters 3. Extended Letters |
| when letters are drawn neither too narrow nor too wide | Normal letters |
| 6 units H & 0 unit W | I |
| 6 units H & 6 units W | TOMQVAXY |
| 6 units H & 8 units W | W |
| 6 units H & 5 units W | Remaining letters of the alphabet except I TOMQVAXY W |
| –these letters are narrow in width in proportion to the height and are used when spaced is limited. | Compressed letters |
| – these letters are wider than the normal letters and are used when the space is very wide | Extended Letters |
| - The upper portion of certain letters and numerals are reduced in size where possible to produce the effect of stability and a more pleasing appearance | Stability |
| The central horizontal strokes of these letters are drawn slightly above the center | B, E, F and H |
| - Absolutely essential for good letterings - May be light horizontal type used to regulate the height of letters | Guidelines |
| - May be light vertical lines used to keep letters uniformly vertical - Fine, light, straight and parallel with cap line and base line identified for upper case letters and with waist line and drop line for lower case letters. | Guidelines |
| What are included in the guidelines? | Cap line, waist line, base line, drop line |
| The background areas between letters, not the distances between them, should be approximately equal | Spacing of letters and words |
| Space words well apart, but space letters closely within words | Space "O" |
| the size, length or amount of something established | Measurement |
| it denotes an instrument or device is used to ascertain the size, amount or degree of something | Measuring |
| the distance between the two given points and is determined by the unit length | Linear Measurement |
| Instruments used in making technical drawings of full size objects at a given enlargement or reduction | Scales |
| Types of Scales | 1. Metric scale 2. Civil Engineer's scale 3. Architect's scale |
| the standard in most of the world. uses the millimeter as its base measurement. | Metric scale |
| Common scales 1:50, and 1:5. For example, 1:50 scale equals onefiftieth (1/50) full size--or 1 millimeter on the drawing equals 50 millimeters in reality | Metric scale |
| are used to design large projects such as roads, bridges, and water mains. Depending on the project, 1 inch on the scale can represent 100 feet in real life | Civil engineer's scale |
| convert inches into feet and always read X inches = 1 foot 0 inches. The scale 1/4 inch = 1 foot 0 inches means that 1/4 inch in the drawing equals 1 foot in the actual building The size of the drawing is 1/48th the size of the actual building | Architect's scale |
| used to draft plans of large and smaller scale projects. These include buildings and structures, as well as interior and exterior dimensions of rooms, walls, doors and windows | Architect's scale |
| In technical drawing, objects are often drawn _________. This term refers to the relationship between the size of the object in the drawing and the actual size of the object | To scale |
| means that the size of the object in the drawing is the same size as the actual object after it is manufactured | Full scale (1:1) |
| means that the size of the object in the drawing is half the size of the actual object after it is manufactured | Half scale (1:2) |
| means that the size of the object in the drawing is twice the size of the actual object after it is manufactured. - an enlarged scale, are used on objects that are too small to draw full size with any meaningful detail | Double scale (2:1) |
| - Each line on a technical drawing has a definite meaning and is drawn in a certain way. - Two widths of lines are recommended for use on drawings | Alphabet of Lines |
| thick, dark line used to show the outline of the object and defines features you can see in a particular view: ___________ | Visible line |
| short dash lines used to show non-visible surfaces, usually shown as medium thickness: ---------- | Hidden Line |
| long and short dash lines. Usually indicates center of holes, circles and arcs: ______ __ ________ | Center line |
| a light line that extends from the edge or end of a main object line on a drawing. Used in conjunction with dimension lines to help determine the dimension of a particular feature. -not connected in edge of main object line | Extension line |
| thin and dark lines used to show the size of an object with a numeric value. Usually terminates with arrowheads or tick markings -> | Dimension line |
| used to designate where an imaginary cutting took place: long short short long with arrows | Cutting plane line |
| thin lines used to indicate the surface in the section view imagined to have been cut along the cutting-plane line: ///// | Section line |
| – a thin line used to connect a dimension line with a particular area or point on the drawing. It is also used to show notes or labels. | Leader line |
| are used when it is desirable to shorten the view of a long part | Short-break line/Long-break line |
| wavy: ~~~~~~ | Short-break line |
| Zigzag: zzz | Long-break line |
| – long line followed by two short dashes used to show alternate position of a moving part | Phantom line |
