Format for Information Transfer

Each time the export link is invoked, one neutral file will be created. Thus, each one can contain information about one or several model objects.

• Each model object consists of one or several primitives. These primitives must not intersect. If they do, it will cause unnecessary interference, erroneous visualization and unnecessarily increased process time.

• Each neutral file contains a number of lines with a variable number of characters, maximized to 80. Each line starts with a keyword. Some of the keywords are followed by a comma and a parameter, belonging to the keyword.

• There must be a semicolon at the end of each line. The order of keywords is highly relevant.

• Parameters can be of four types: keywords, strings of characters, integers or reals.

• Strings must be surrounded by apostrophes. Reals can be with or without exponent but must be readable by FORTRAN and C programs.

• Blanks are allowed between terms, parameters and separators but irrelevant, except within string parameters.

• The use of keywords for solid primitives are exactly the same as for the link which converts a neutral file into objects.
