Units 

GiD_Units edit|get magnitude_units|magnitudes|model_unit_length|system ?<value>?
To allow get or modify units and magnitudes.
Note: units doesn't exists without load a problemtype that define them

• GiD_Units get magnitude_units <magnitude>

Returns the list of allowed units for the <magnitude> (of the current unit system)
<magnitude> must be one of the values returned by [GiD_Units get magnitudes]

• GiD_Units get magnitudes

Returns the list of defined magnitudes

• GiD_Units get system

To return the current units system string
e.g.
GiD_Units get system
-> SI

• GiD_Units edit system <value>

To set the current units system
e.g.
GiD_Units edit system imperial

• GiD_Units get model_unit_length

To return the current geometry length unit string.
This unit declare the length unit of the coordinates of the geometry or mesh
e.g.
GiD_Units get model_unit_length
-> m

• GiD_Units edit model_unit_length <value>

To set the current geometry length unit.
<value> must be one of the values returned by [GiD_Units get magnitude_units <length_magnitude>]
Where <length_magnitude> must be the length magnitude name. This name depends on the problemtype units definition (L, LENGTH, or others)

e.g.
GiD_Units edit model_unit_length mm
