TYPES OF LINE
It is used for showing visible details of the object
3) Visible 0.4 to 0.5 mm Dark Object line
No. Line type Illustration Thickness
LENGTH 3 TO 4 mm.
1) Construction line 0.1 to 0.2 mm Very light projector
2) Leader line 0.2 to 0.3 mm Medium dark Extension line Section line
5) Center line, Axis 0.1 to 0.2 mm Medium darkt The line of Symmetry
4) Dimension Line 0.2 to 0.3 mm Medium dark
It is usually extended beyond the out line of the object
THICKNESS NOT MORE THEN 1MM.
Special care should be taken to draw arrow heads. It should be as dark as the dimension line. Draw two lines of the arrow heads so close that their is no need to fill it with the pencil. generally arrow heads becomes darker due to filling it with the pencil.
6) Dotted Line or 0.4 to 0.5 mm Dark Hidden line

Multiview Orthographic Projection
First angle orthographic projections : Refer figure Below:
1) The object is above H.P. and in front of V.P.2) The plane of projection is behind the object.3) The common line between H.P. and V.P. is known as X Y line.4) The common line between V.P. and PP is known as X1 Y1 line.5) All the planes are opaque and hinged to vertical plane as shown in the fig.6) Front view shows Length and Height of the object.7) Top view shows Length and Width of the object.8) Side view shows Height and Width of the object.

Lets start drawing First Level of Front Face “f1” with Bottom most line at origin “O”.
Accordingly Draw Second Level of Front Face “f2” as shown Follow the same method of projection to Develop the Top View & Left Side view.
