Figure 83 and Plates 22 and 23 are indicative of what might be obtained from a class. The problem represented on Plate 23 is advantageously colored with the intended stain and with a small section of side wall and trim visible. See Chapter 16, Figures 458 to 463. Figure 102a shows the method of enlarging a design into a full size working drawing for shop purposes.
(_b_) Subdivide the rectangle into vertical and horizontal divisions.
(_c_) Determine parts to be treated by contour enrichment.
(_d_) Determine method suited to the project: wood turning, moulding, etc.
(_e_) Group the wood turning curves under a definite system included under Rules 2a and 2b. Group the mouldings under crown, intermediate, and base classifications. Add this enrichment to the primary mass or make other simple variations that will not destroy the unity of the project.
(_f_) Dimension and otherwise prepare the drawing for shop use.
_Note_.--If the designer is not properly equipped to prepare his own mouldings, he should consult moulding catalogs or the stock of some local lumber company.
Design a wood pedestal with the curves grouped into three horizontal divisions.
Design a hall table 2 feet 10 inches high and add simple contour enrichment.
Rule 5a. _Outline enrichment should be subordinated to and support the structure._
Rule 5b. _Outline enrichment should add grace, lightness, and variety to the design._
Rule 5c. _Outline enrichment, by its similarity, should give a sense of oneness or unity to the design, binding divergent members together._
2. What two forms of enrichment are commonly used in industrial arts design?
3. What four qualities are added to industrial design by contour enrichment?
4. What disturbing elements should be guarded against in the application of contour enrichment?
5. Describe the curve of force and its function in the contour enrichment of wood.
6. What are mouldings? Name three types of mouldings, their positions with relation to the eye level, and some curves used in their design.
7. Give examples of curves of continuity and contrast. By what means should two contrasting curves be separated?
8. How should a curve join a straight line?
9. Explain the grouping of contour curves in wood turning projects similar to a round leg or candlestick.
