Define tool-specific unit IDs
Use the unit management system (UMS) spreadsheet to define the unit ID of your new units of measure.
NX Unit ID
UMS works with Classification's "NX Unit ID" attribute as described in managing units of measurement. You can configure the unit's value in the unit_definitions file and then run the ums_import_unit_definitions utility with the -allowOverwrite flag to update the display units.
Custom alias unit ID
You can add a tool-specific unit alias ID for another tool, such as HEEDS.
Procedure
- Create a new attribute dictionary definition on the Unit Definition Class using Classification Admin in the rich client to store your new column.
- Create a new attribute in the Classification dictionary, e.g. named "HEEDS Unit ID".
- Define the format as
STRING(60)and default value asEMPTY. - Add the new attribute to the Unit Definition Class.
- Change the User Data 1 field value to
Alias:HEEDS. - Add a new column named "HEEDS Unit ID" to your
unit_definitionsfile and add your values. - Run the
ums_import_unit_definitionsutility with the-allowOverwriteflag to update the display units.
