10、changing the technical contents. International Standard. For drawings for tender, manufacturing drawings and setting drawings in pipe- line construction as well as in machine construction and the construction industry, isometric projection has been introduced to a great extent, since it reduces draw
11、ing work and it makes the presentation clearer. For the purpose of this part of JIS B 0011, all dimensions and tolerances on the drawings has been stencilled in upright lettering. It should be understood that these indications can be freehand writing or inclined (italic) lettering without altering t
12、he meaning of the indications. The matters underlined with a dotted line in this part is not included in the original For the presentation of lettering (proportions and dimensions), see JIS O01 1-1. 1 This part of JIS B O 0 1 1 specifies supplementary rules, in addition to the general rules given in
13、 JIS B 0011-1, applicable to isometric representation. Iso- metric representation shall be used where the essential features are to be shown clearly in three dimensions.
