Directly after opening of the dialog box the right side is still empty.

If you want to create a new mapping, double-click on the desired "gray" class. The dialog box (the wizard) Mapping the class system [Map class system] opens.

[Note]Note

Does it matter whether, for example, ECLASS 4 is mapped to ECLASS 5 or vice versa?

Yes, it does matter. This shall be explained with a small example:

ECLASS 4 class 01-02-03-99 is divided more precisely into:

  • ECLASS 5 Class 01-02-03-01

  • ECLASS 5 Class 01-02-03-02

  • ECLASS 5 Class 01-02-03-03

  • ECLASS 5 Class 01-02-03-04

Then a mapping from ECLASS 5 to ECLASS 4 could work automatically (all projects that use one of the four ECLASS 5 classes are classified according to the one ECLASS 4 class).

However, mapping from ECLASS 4 to ECLASS 5 may not work automatically because the mapper does not know which of the four options to use if it finds a project that was classified according to ECLASS 4 class 01-02-03-99.

To be able to resolve these cases, the mappings of ECLASS 5 -> ECLASS 4 and ECLASS 4 -> ECLASS 5 are two separate mappings.

In the following sections you can find information on the single dialog pages of the wizard.
