Unit specification in XML file
The unit type is written to the XML Template by writing according to the Unit types table, e. g. UnitType="Length^2/Force"
The unit definition for the specified unit type is written to the XML Template as a list of basic units separated by | , e. g. UnitDefMetric="m|kN" UnitDefImperial="in|kip"
The unit for certain data is written to the XML Data by taking text from the Unit Types table and adding an underscore and a specific unit to each base unit specification, eg. Unit="Force_kN*Length_m/Angle_rad/Length_m"
Units description
The currently used Unit System is specified in the task or in the stored data from the following options:
| Name | XML | Description |
|---|---|---|
| Metric | [V] Metric
|
Metric unit system used elsewhere in the World except the USA |
| Imperial / English | [V] Imperial
|
Imperial (English) unit system, inches, feet, pounds etc. |
The unit is determined by the unit type (e.g. Force/Length^2 and consists of one or more basic units (Force, Length). The special unit type is Undefined, for which the unit description is specified by the user.

Exceptions
If the Unit Type is Force/Length^3, the description is adjusted for the following combinations of basic units:
| Force | Length | Popis |
|---|---|---|
| lbf | in | pci |
| lbf | ft | pcf |
| kip | in | kci |
| kip | ft | kcf |
If the Unit Type is AltitudeLength, the description is completed with "n. m.", e. g. "m n. m."
