Units

The user can specify the units for options such as paper size, margin widths, and cutting allowances. The default units are taken from the Catalogue. They can be changed before the value is input by using one of the commands:

MILlimetre

MM (a shorter form of the preceding option)

FInch(that means, feet and inches)

INch

followed, in the same command line, by one of the options:

BOres

DIstances

to define the type of measurement to which the units are to apply. This sets the current units, which remain in force until reset.

For example, a loose flange allowance could be specified in feet and inches by the command sequence:

FINCH DISTANCES

LOOSE 1’6

Alternatively, values may be input together with their corresponding units regardless of the current unit settings. Thus the previous example could be replaced by the single command

LOOSE  1 FT  6 IN

without affecting the current unit specifications.

The current units may be queried at any time by using the command

Query  UNIts

Units for dimensions on the isometrics are specified by the UNITS command. They can be queried by the Q OUTPUT UNITS commands.
