Introduction to Day 19
Today, under Warm up, we quickly revise all Workouts in Sessions 1-4, and upto Day 18.
For Workouts, we practice some more variations of sinuous lines and springs, and also use shroud and change tools for some of these exercises.
Under Sense of Perspective Space, we learn how to draw Vertical and Horizontal Cylindrical Objects in One-Point Perspective

• Grid: G2, G13
• Different drawing tools
• Tracing sheets
• Measuring ruler/scale
Overall Time Plan:
• Warm up : 15 mins.
• Workout : 60 mins.
• Sense of Perspective Space : 90 mins.
15 minute Exercise:
0-5 mins : Practice very fast hand and body movements while drawing Horizontal, Vertical and Inclined Lines, Curvatures, Radial Lines and Rings, and various Sinuous Lines and Springs, recalling this and all earlier sessions.
5-10 mins : Now, repeat the various workouts covered in Session-1-4, and upto previous day WITHOUT the underlay grids by CHANGING TOOL (use an H or 2H pencil today). As a warm up exercise using a different tool, the focus should be on maintaining line uniformity as well as good fluency of the drawn lines.
While drawing these, remember to:
1. Draw them for various lengths, diameters and radii.
2. Draw lines in either direction and curvatures, both clockwise and anti-clockwise.
3. Draw them at various pace - fast, slow, fast to slow in a single line, etc.
This practice of initially drawing the lines fast and then slowing down will help your body get into smoother drawing action for the workouts and perspective exercises ahead.
<Warm up Ends>
Today's practice plan includes repeating today's entire workout session using
(b) Change of tools (10 minutes) and
(a) Shroud (10 minutes).
Therefore, try to finish all the exercises mentioned in this workout session within the first 25 minutes.
1. Aim: Drawing repeating curve profiles: Sinuous Lines and Springs that are diagonally oriented, correctly
• Improve line quality
• Improve fluency
2. Set up:
• Tracing sheets, soft pencils, music
• Grid - G2, G13
Diagonally Oriented Sinuous Lines and Springs
Variations explored: Offsetted, Tilted, Progressive/Regressive. Use of different tools, shroud.
19.1) Vertical Sinuous Lines/Springs - 10 mins - 1 sheet
Practice Vertical Sinuous lines and Springs in the 5x15 grid template G2, as sets of successive lines as well as offsetted lines as shown below. To begin, practice for the following values:
(a) a = 7.5cm; p = 10cm,
(b) a = 5cm; p = 15cm.

19.2) Tilted, Progressive/Regressive Horizontal Sinuous Lines/Springs - 10 mins - 1 sheet
Image 19.2: Tilted, Progressive and Regressive Vertical Sinuous Lines and Springs
Continue to use the 5x15 grid template G2 for this exercise. Maintain the gradual increase in amplitude for the progressive and regressive curve profiles.Use pitch, amplitude and frequency values of your choice for this exercise and incorporate variations such as reversal of drawing direction, different tilt angles, etc.
19.3) Regular/Offsetted Diagonally oriented Sinuous Lines/Springs - 10 mins - 1 sheet
Draw sets of regular sinuous lines and springs successively at 2cm gap on a dense 45 degree diagonal grid (GT13). For a start, vary the pitch and amplitude as follows:
(a) a = 10cm; p = 7.5cm for a sinuous line
(b) a = 15cm; p = 5cm, with overlap = 2.5cm for a spring, as in the sample sheet below.
Note: It is highly essential that the forearm is at a perpendicular to the edge of the board.
Repeat by offsetting to the right. Maintain equidistant spacing between consecutive lines.

19.4) Tilted, Progressive/Regressive Diagonally oriented Sinuous Lines/Springs - 10 mins - 1 sheet
Using the same grid template G13, Draw tilted diagonally oriented Sinuous Lines and Springs, maintaining the relative tilt, as shown below. For Progressive/Regressive curves, ensure the change in amplitude is gradual.

19.5) Redo with Change of Tools - 10 mins - 1 sheet
Repeat all that you covered in today's session by switching between various tools such as brushes, pastels and a rapidograph in the next 10 minutes.However, a lot of you might need more practice, so feel free to continue until you feel more confident about your line quality.
19.6) Redo with Shroud - 10 mins - 1 sheet
To conclude, repeat by using a shroud for the concluding 10 minutes of this workout session. If you feel up for it, you could use a different tool, say a fineliner/microtip pen while drawing with a shroud, for added complexity.
Sense of Perspective Space
Discussion: Drawing Cylindrical Objects oriented Vertically or Horizontally in One-Point Perspective
Vertical and horizontal cylinders are easiest to draw accurately in One-Point Perspective, the reason being:
(a) There is no taper along the vertical in case of a Vertical Cylinder,
(b) the Horizontal Cylinder is composed of successive perfect circles (assuming Vanishing point lies outside object, midway)

2. Set up:
Tracing sheets, measuring ruler.
