other shape code number, form of designation or abbreviation shall
be used in scheduling.
A dimensional sketch
shall be drawn over the dimension columns A to E. Every dimension
shall be specified and the dimension that is to allow for permissible
deviations shall be indicated in parenthesis, otherwise the fabricator
is free to choose which dimensions shall allow for tolerance.
