May 14, 20113 MIDTERM PROJECT INSTRUCTIONS: You may use your class notes and textbook. You may not use anyone else's notes or receive help from another student. If you have a question or cannot proceed without help, ask me. 1. Use the guidelines provided and neatly letter the following statement: (10 pts) THE IMPORTANCE OF GOOD LETTERING CANNOT BE OVER-EMPHASIZED, THE LETTERING CAN EITHER MAKE OR BREAK AN OTHERWISE GOOD DRAWING 2. Using the indicated scale, measure cach line and write your answer in the space provided. (20 pts) Metric 1:100 Engineer's 1"-30 Architect's Full Size (Fractional Inches) Architect's 1/4" 1-0" ingh Hand sketch a multi-view layout (front, top and right) of the part shown. Include visible, hidden and centerlines. Additionally, produce a 10-15 word note on the drawing. Your note(s) can be a standard tolerance note and/or a material note, for example. Use proper lettering to format your note(s). 3. TS CBORE 38 DEEP In the drop box, submit a scanned image of this sheet with your responses and a scanned image of your hand drawing. HEAT TREAT 1O-250 CRS I REQDExplanation / Answer
1. Lettering enables the technical communication regarding the drawing with different people such as drafter, engineer and client etc. thus it is very important to use a standard lettering following certain rules to convey information about drawing features. This makes conveying information consistent, efficient and easy. Follow the guidelines provided to you and practice as much as possible to master this skill.
2. Scales are used to draw real life object on paper. Depending upon the requirements and convenience various scales are used.
Metric: 1 cm = 1 m ( i.e. 1 cm on paper = 1m in real life)
Engineering: 1" = 30 feet (or 1" = 360" or 1:360, for big area)
Full size : 1:1 ( means if 1" on ground then 1" on paper, detailing)
Architecture 1/4" = 1'-0" ( 1/4" = 12" or 1:48 or scale factor 48 )
Now measure the given lines using units mentioned and convert. e.g. in first case measure given line in centimetres and convert as 1cm = 1 m.
It's like you are given a secret map to a treasure with conversion units, you just have to convert and walk that distance in given direction to find it. Hope it helped.
