Units in Outfitting

Distance and bore units are handled in much the same way as before and should need no conversion. Other attributes will now be converted to and stored in appropriate units. Where a database has stored all quantities of a dimension in the appropriate unit, the new functions can be used without upgrade.

Attributes other than distances and bores have the UNIT field set for the first time; in previous versions of AVEVA Hull and Outfitting, they were until now stored as values with no specified unit, other than by use and convention - they could change from application to application, and project to project. This approach is not compatible with automated conversion so the storage units must be defined. For compatibility, it is possible to set the units to NUMERIC which will disable Units conversion for that physical dimension. Disabling a specific dimension in this way means that no advantage will be gained from the introduction of that dimension.

Previous versions of Schematic Model Manager had special units support for Angle, Area, Pressure, Temperature, Volume and Weight values that could be included in the ISO15926 format import file. Units UDAs were provided as mandatory UDAs and were attributes on each Diagram element (SCDIAG). The chosen units for these dimensioned quantities could be set in the Project Options form in Schematic Model Manager. In 12.1, the new units capabilities mean that the special units support in Schematic Model Manager is no longer required. Data imported in 12.1 will be stored in the appropriate units consistent with the data read from the ISO15926 import file. The upgrade process for projects moving to 12.1 includes a part upgrade for Schematic Model Manager dimensioned data.

Please note that the CATA database elements MSET, MTYP, ATLI, USEC and UDEF are no longer used; they will be removed from the database in due course.
