# CTE Resource Center - Verso - Engineering Studies Task 1132453215

Sketch orthographic and isometric projections.

Definition

Sketching should include
• using sketching techniques to sketch standard projections
• using simple engineering drawings as examples.
Optional approaches may include
• using basic technical drawing instruments
• using basic technical drawing techniques to draw standard projections
• using drawing instruments in accordance with standard procedures.

Process/Skill Questions

• What are the three primary views used in multiview drawings?
• What is orthographic projection? Why is it important to identify the front view of an object?
• How is the front view of an object identified?
• Why are pictorial drawings used?
• What is the isometric axis, and why is it important?
• What are non-isometric lines? What are some examples?
• What are the steps in drawing a pictorial view from a multiview drawing?

Mathematics

G.3

The student will solve problems involving symmetry and transformation. This will include
1. investigating and using formulas for determining distance, midpoint, and slope;
2. applying slope to verify and determine whether lines are parallel or perpendicular;
3. investigating symmetry and determining whether a figure is symmetric with respect to a line or a point; and
4. determining whether a figure has been translated, reflected, rotated, or dilated, using coordinate methods.

G.14

The student will apply the concepts of similarity to two- or three-dimensional geometric figures. This will include
1. comparing ratios between lengths, perimeters, areas, and volumes of similar figures;
2. determining how changes in one or more dimensions of a figure affect area and/or volume of the figure;
3. determining how changes in area and/or volume of a figure affect one or more dimensions of the figure; and
4. solving problems, including practical problems, about similar geometric figures.
