Set of Seven Drawings
A picture is worth 1,000 words and so technologists often communicate in drawings instead of text. To ensure effective communication and minimize confusion, standards are followed.
There are several ways in which objects are portrayed. Pictorial sketches look like the object. Three kinds of pictorials are isometric, oblique (cavalier, cabinet, or general), and perspective (one point, two point, or three point). There are also multi-view drawings where each face is shown separately. The most common multi-view is the orthographic.
To complete this task you must:
- Get a sheet of objects from the teacher. There are easier ones and more difficult ones available.
- Sketch seven objects to make a presentation set on orthographic paper.
- The sketches for each object should include a pictorial and a multi-view.
- Additional drawings may be done for extra credit (see formula below).
- Drawings that receive a grade of B or C may be reworked. The grade for the reworked drawing will replace the grade for the original drawing.
- Drawings that receive a grade of D must be reworked. The grade for the reworked drawing will replace the grade for the original drawing.
- Present your Set of Seven drawings to the teacher for evaluation
The sketches for each object will be graded on an A, B, C, D scale. 4 points will be awarded for each A, 3 points for each B, 2 points for each C and 1 point for each D. Seven object drawn correctly in every way will result is a total score of 28 points for this activity.
S = 34 x T / (P + 6)
- S is the score out of 28 points
- T is the total points earned
- P is the maximum possible points (i.e. the number of drawing times 4 points per drawing) but not less than 28
Evaluation of the drawings for each object will be based on the following:
- Correct method used to create pictorial box
- Pictorial correct
- Tonal shading added to pictorial
- Correct method used to create multi-view box
- Object show correctly in multi-view
- All hidden lines shown
- Adequate contrast between construction and object lines
- No overstrokes
- Construction lines used to line up views
- An adequate number of views in proper order
- One object per sheet
- Drawings in pencil
- Pictorial in upper right
- Multi-view in remaining area
- Fill in the title strip on each sheet
