Dimension Numerical Display

The following task explains the methodology for managing V5 Dimension Numerical Display standards for V4 to V5 migration. You will learn: 
  • how the migration of Dimension Numerical Display is carried out,
  • and what you need to pre-define concerning the V5 standard parameters before starting the migration process.
V4 Numerical Displays are known as Value Display Formats in V5.

Migration mechanism

The migration engine tries to map the name of the V4 Numerical Display used by the dimension to migrate to the name of a V5 Value Display Format:

  • If a V5 Value Display Format bearing the same name as the V4 Numerical Display is found, then this Value Display Format will be applied to the new dimension in V5. 
  • If not, all existing V5 Value Display Formats will be scanned and the closest description will be used. However, the result will not be exactly the same.

Pre-definition

There are two possibilities:

  • If you used a standard PRJ (delivered by DS), you do not have to customize anything in particular before migrating the V4 2D Models.
  • If you created a specific Numerical Display in V4, you need to re-create it in V5. If you do not then, dimensions which use this Numerical Display will not be mapped during the migration and the result will be different than in V4.

In V4, the Numerical Display (including all its parameters and values) is defined in the DRWSTD function, under Annotations > Description > Visualization > Numerical Display.

In V5, the Value Display Format is defined in the Standards Editor, under Standard > name_of_standard > ValueFormats. 
Some of the pre-defined Value Display formats which are provided by default in V5 cannot be modified: for example, NUMM.DIMM, DISTINCH, etc. Since they cannot be edited, these formats do not appear in the Standards Editor.
