NOTE: This is a suggested outline. Topics and assignments may vary. Classwork and homework represent a group of suggested problems. Assignments will vary as determined by your instructor. Some of the homework assignments will be from the back of the chapter, and some will be assigned from the Drawing pages in the back of the book.

Getting acquainted with the various drawing instruments. Using two triangles as a pair for parallel and perpendicular lines.

Read: (T) Ch. 1 and Ch. 2 Proper lettering for the professional look; use of the Ames lettering guide.
Read: (T) Ch. 4, especially Sections 4.16 and 4.17.
HW: Use the Ames lettering guide and refer to the instructions in the insert.
Use 1A paper, use 4H or 3H lead to draw light guide lines; use 2H or HB pencil and print the assignment per Drawing 4.3 or 4.4.

Scales for Dimensioning and Sizing. Learning to read scales to eliminate the need for algebraic conversions of measurements. Measurements are read directly from the various engineers' or architects' scales.

Read: (T) Ch. 2, Sections 2.24 - 2.32.
Class: Drawing 2.2 (Instructor may use pages 54 & 55 from Reference workbook.)

Geometric Construction. Using plane geometry concepts to understand how lines and angles blend.
        Read: (T) Ch. 5, Sections 5.1 - 5.43.

Multiviews for three dimensional viewing. Revolving the object for different perspective views. Proper layout of orthographic views.

Read: (T) Ch. 6, Sections 6.19 - 6.31.
Class: (T) Figure 6.52 or 6.53, select some forms for multiviews.
HW: (T) Figure 6.53, construct the multiview for the same isometric done last week.

Orthographic projections. Using the glass box concept and revolving an object to see the principle views in orthographic layout for drafting and model making. Review the seven principle planes for description and references.
        Read:&(T) Ch. 7
        Class: (T) Fig. 7.1, 7.2, 7.3, 7.4, 7.16, 7.43, 7.46
