Overview
The main manipulations possible on an analysis (MLD) are as follows:
Note The terms "MLD" and "Analyse" are used interchangeably to define the database structure associated with a project.
Handling an analysis (MLD)

Duplicate/Copy an analysis

Duplicating an analysis makes it possible to have two identical analyses with different names.
To duplicate/copy an analysis:
  1. Open the analysis to duplicate in the data model editor.
  2. On the "Home" tab, in the "General" group, expand "Save" and select "Save as". The analysis description is displayed.
  3. Modify the analysis name and directory.
  4. Confirm changes:
    • All files used to describe the duplicated analysis are automatically copied into the specified directory.
    • The duplicated analysis is automatically associated with the current project.
Note The backup subdirectories of the original analysis are not copied. The new analysis contains no backup.

Delete an analysis

To delete an analysis:
  1. Open the Windows explorer.
  2. Delete the full directory of the analysis (<Project name>.ANA directory).
Note If a project uses this analysis, it will be necessary to associate the project with another analysis when opening it.

Rename an analysis

To rename an analysis:
  1. Open the analysis to be renamed in the data model editor.
  2. On the "Home" tab, in the "General" group, expand "Save" and select "Save as". The analysis description is displayed.
  3. Enter the new analysis name.
  4. Confirm changes.
  5. All files used to describe the renamed analysis are automatically copied into the specified directory.
  6. The renamed analysis is not automatically associated with the current project. Associate (if necessary) the renamed analysis with the current project. For more details, see Linking an analysis to an existing project.
  7. In the Windows explorer, delete (if necessary) the directory of source analysis.

Linking an analysis to an existing project

To link an analysis to an existing project:
  1. Open the project to associate.
  2. On the "Project" tab, in the "Project" group, click "Description". The project description opens.
  3. In the "Analysis" tab, click on "Add analysis" and select the path of the WDD file corresponding to the analysis you wish to associate.
Remarks:
  • Several analyses can be associated with a single project. For more details, see Project with multiple analyses.
  • Deleting an analysis and replacing it with a new one: If data from the original analysis is manipulated in the project, associating a new analysis can lead to errors (duplicate errors, display errors, etc.).

Zoom factor

You can specify a zoom factor in the data model editor to reduce or enlarge the graph display of the current analysis.
To specify a zoom factor:
  • 1st method:
    • On the "Display" tab, in the "Help for edit" group, choose the desired zoom factor.
    • Enter the zoom factor in the status bar of the editor (bottom right).
  • 2nd method:
    • Press the Ctrl key.
    • Modify the zoom factor with the mouse wheel while keeping the Ctrl key down.

Move the display of an analysis

To move the display of an analysis:
  1. Display the analysis in the data model editor.
  2. Press the Alt key.
  3. Change the position of the analysis graph by holding down both the left mouse button and the Alt key.
