ISO 14985 pdf download.Hard-copy output of engineering drawings — Specification for the structure of control files
1 Scope
This International Standard specifies the structure of a control file that can be used for the output of electronic images of engineering drawings to various forms of hard-copy output devices. This International Standard is not intended to define a minimum standard for the hard-copy device since different devices may support different features according to their complexity and intended use.

3 Terms and definitions
For the purposes of this International Standard, the terms and definitions given in ISO 61 96 and the following apply. 3.1 X axis horizontal axis of an image when the image is correctly oriented for viewing 3.2 Y axis vertical axis of an image when the image is correctly oriented for viewing 3.3 plot control file file used to control the way in which a drawing will be produced on a hard-copy plotting device 3.4 job control file file used to control the way in which a sequence of drawings will be produced on a hard-copy plotting device
4 Structure of Plot Control File
4.1 Format The format of the plot control file is shown in Table 1 . The language used for the plot control file structure and text options shall be English, and the file shall be in ASCII text format. Text strings may be in any language. 4.2 General Requirements The plot control file shall comply with the following general requirements: a) The plot control file shall begin with a section key labelled [ PLOT CONTROL FILE HEADER ] and shall terminate with a section key labelled [ END OF PLOT CONTROL FILE HEADER ]. b) Each group of settings between the section keys shall start with a group key, which shall be enclosed in square brackets: [ IMAGE FILE ], [ DRAWING OUTPUT ], [ PENS ], [ ANNOTATION ], [ MEDIA ], and [ FINISHING ]. c) The header structure shall indicate whether the several settings following each group key are mandatory or optional. d) A carriage return or line feed character, or both, shall separate entries in the file header. e) The field identifier shall terminate with an equal sign (“=”). f) Blank lines and spaces shall be ignored except when enclosed within quotation marks. g) Treatment of the data shall be case insensitive except for text strings to be used for annotation. h) If the first valid character on a line is a semicolon, the line shall be considered a comment line. Comments shall occur only between the start section key and the end section key. i) When the data in a plot file produces any type of conflict, the plotter shall produce the best plot it can rather than reporting an error.
