Compare Diagram

Compare Diagrams

You can compare models and diagrams in two files you created with Astah System files. Differences can be shown in a list and also in diagrams visually with markups.

1. Open a file then go to [File] – [Compare Project and Merge].
   
   
   
2. Select another project file to compare.
   
   
3. [Differences] pop-up opens with a list of diagrams and models of both project files in a tree view side-by-side.
   
   
   Diagrams and models that have differences will be indicated with color:
   – Blue: This model exists in both files but something is different than one in another file
   – Red: The model does not exist in the file but exists in another file
   – Green: The model exists only in one file and not in another file
   
   
   
4. If you want to see the differences in diagrams visually. Select a diagram in the tree view and click [Open Compare Diagram].
   
   
   
5. Two diagrams open with markups.
   

You can merge files

If you’d like to merge two projects into one after comparing the models, click the [Merge] button.
