  1. Blueprint Drawing and Interpretation - Skilled Trades 1201

  2. 1. Discuss the "Alphabet of Lines" used in technical drawings. Note the WEIGHT of certain lines as "thin" or "thick".

  3. 2. Evaluation - Draw a table on an 8.5x11 sheet of paper with 11 rows and 3 columns. For each row, draw three duplicates of one of the line types (in the left column), in pencil, paying attention to the weight of the line. Put your name on the sheet of the paper and put it in your folder.

  4. 3. Evaluation - On the back of the sheet used above, list the letters A through J and identify the line types used in the technical drawing below:

  6. An Isometric Drawing - Observe the two figures in the drawing below. Note how the figure (1) in the top right hand corner is in a "3-D View'. This is an Isometric View. It is similar to a perspective drawing one might draw in art class, but simplified so that the three major axes of a box are drawn vertical, and at 30 degrees from horizontal to the left and right. This makes them easy to do with mechanical drafting tools. All faces of an isometric are drawn using the same scale) The basic "box" of an object has 6 faces. It is a convention (standard practice) to draw it with the longest face to the left. In this case, however, the longest face is drawn to the right.

  7. Creating an Orthographic View - An Orthographic View includes the side, top, and front view of a figure. Note the lines (2 and 3) extending from the representation of one of the faces(1) of the figure.

  8. In the next picture, note how the lines can be used to aid in the drawing of the other two sides. Now we have a drawing with an Orthographic View and an Isomertic View in the top right corner. In this drawing the top is red/yellow, the front is blue, and the side is green.

  9. 5. Evaluation

  10. For the following figure, create an Orthographic Drawing with a front (blue), top (pink), and side (green). Note that you will have to use "hidden lines" to represent some of the edges. The drawing should fill most of an 8.5x11 sheet of paper, be drawn in pencil, and should be drawn with the aid of a ruler. Put your drawing in your personal folder.

  11. 6. Discussion of House Plans

  12. In this section, we will explore the various types of drawings used to direct the construction of a house with a focus upon the trades explored in this course.

  16. As as class we will examine a reference set containing the common symbols found in a set of house plans. We will use this reference to identify features such as:

  17. overall dimensions of rooms

  18. locations of doors, windows and types

  19. common architectural symbols for appliances etc

  20. Locations and number of 120 volt receptacles

  21. Locations and number of lights

  22. Locations and number of switches and the devices they control, distinguishing single, and three-wayswitches

  23. all water appliances

  24. the location and number of valves and other water control devices

  25. the approximate number of feet required of each type of pipe

  26. the number of fittings (90s, 45s, couplings, etc) needed to install pipe runs

  27. Evaluation - Using 8.5x11 paper, you will draw a floor plan and elevation plan for a cabin based upon specifications provided by your teacher. In the floor plan, you will provide information on doors, windows, furniture location/built-ins/appliances, electrical, and plumbing. You will draw the floor plan first and derive the elevation plan from it.
