Advanced Compare projects options:
In the same dialog, click the
Advanced button to see more compare options. The Use the older project as Base option is selected by default. This means that the project whose creation date is older is set as the Base project, while the one that was created later is set as the Compared one (i.e. the projects you indicated as the Compared and the Base might end up being swapped based on their creation date). In this case, all changes are marked as made in the Compared project. If you deselect the Use the older project as Base option, the Base and the Compared projects will remain as you selected them in the Compare Projects dialog.

In the Optimize for drop-down list, select
- Speed, to compare the projects faster. This is the default option and it is sufficient for most projects. Keep in mind that this option requires more memory.
Memory, to compare bigger projects. Sometimes the memory required for the Speed compare mode exceeds the memory available for MagicDraw on your machine. In that case, switch to Memory mode, which conserves memory. However, this option slows the procedure down considerably.
