fhe process adopted by tlie author of making this tracing is as follows : 
Tracing in circles or parts of circles. 
” ” lines showing straight parts of members. 
” ” freehand curves of members. 
” ” centre lines. 
Putting in dimension lines. 
Marking off dimension points or arrow heads. 
Writing dimensions. 
Sectioning parts shown in section, 
i'iug a separate mark to eacli piece, 
utfcing on bill of material shown on drawing,
