Synopsis

&DUNIT

Description

Controls the units used to create all linear dimensions such as horizontal, vertical, perpendicular, parallel, diameter, radius, etc. This unit does not apply to angular dimensions.

Characteristics

Read/Write - Number - [1..5]

Constant Values

1 = &MM
2 = &M
3 = &INCH
4 = &ARCHFI
5 = &ENGFI

Parameters

Parameter

Description

&MM

GPA which indicates that the units of all linear dimensions will be millimeters.

&M

GPA which indicates that the units of all linear dimensions will be meters.

&INCH

GPA which indicates that the units of all linear dimensions will be inches.

&ARCHFI

GPA which indicates that the units of all linear dimensions will be architectural feet and inches. Any number exceeding 12 inches will begin with feet (e.g., 1' 2-1/2").

&ENGFI

GPA which indicates that the units of all linear dimensions will be engineering feet and inches. Any number exceeding 72 inches will begin with feet, and foot measurements will be incremented in 72 inch sets (e.g., 71-3/4" and 6' 4-1/2" and 6' 43-3/4"). Even after 6 feet is surpassed, the foot unit will not change until 12 feet is reached (e.g., 6' 71-3/4" and 12' 4-3/8").
