The document discusses the first angle projection method for creating orthographic views from a pictorial representation of an object. It provides instructions for sketching the front, top, and side views using freehand drawing. The key steps are to first sketch the outline of each view, then add visible lines and circles, followed by hidden lines and circles, and finally darkening all lines to create the finished orthographic projections from the pictorial presentation.

12. General procedure for sketching orthographic views
from pictorial view (isometric view):
Step 1 : Sketch with free hand, the outline of all the required views with
thin line (2H pencil).
Step 2 : Sketch with free hand, all the visible lines and visible circles in
all the required views with thin line (2H pencil).
Step 3 : Sketch with free hand, all the hidden lines and hidden circles in
all the required views with thin line (2H pencil).
Step 4 : After checking for technical mistakes if any, darken (with free
hand) all the visible lines, hidden lines, visible circles/arcs and hidden
circles/arcs forming the required views with HB pencil.
Step 5 : Lettering (both alphabets and numbers) should be done with
free hand.

13. An example :
Make free-hand sketches of front, top and right side views of the
pictorial view shown below.
