Design Scenario

Learning to use the equipment properly is the focus of this chapter. Learning to tear the tracing paper with a straight edge to taping down the sheet is the goal. EXERCISE ONE

Tape down an A-size sheet of paper and divide it into 6 spaces. With the straight edge, proceed to draw in each box with pencil the following lines. 1. Horizontal lines

4. Diagonal lines starting from bottom left

2. Vertical lines

5. Diagonal lines starting from bottom right

3. Crosshatched lines

6. Diagonal crosshatched lines

Draw the next three sets of lines with pen. Be sure to use the 45-degree triangle for precision. (See Figure 2.18.)

 {2.18} 

Line exercise.

EXERCISE TWO

Draw two lines 1 inch apart across a sheet of paper. Starting with the highest H pencil, divide the lines into seven boxes. In each of the boxes select a different pen and shade, starting with the highest H and working to the highest B. Reference Figure 2.19 when selecting pencil hardness. You will have your own scale based on the pressure applied when shading. (See Figure 2.20.)

DESIGN SCENARIO— SECTIONS FROM THE PLAN

Developing a building in section is one method that many designers find beneficial toward understanding the space. They can scale room heights and widths to visually accommodate their concepts. Seeing a design in a vertical form helps many people see if the scale of the space fits the needs. Having a living room with a greater height than the bath is easy to design on a floor plan, but need to be sensible in the overall design. Drawing rooms at various heights throughout the building

can create complex construction issues.

between spaces. A simple way for most designers to reflect an exterior is through elevation and section with the use of a human scale factor. The human scale factor  is a human placed

in a drawing giving a sense height and width. Designing using the scale method allows for the creation of multiple heights, such as the American split-level house. The housing type is based on three levels within a two-story

The details on the front view describe all the components. Cabinets are considered a furniture piece, and the designer must remember that individuals of different heights will be using them. Always research the furniture type and sizes that are required for the end user. The product will need to be creative yet functional.
