With Astah System Safety, you can merge one project file to another. So that you can distribute the work among team members and merge all them into one file.
If you’d like to see the difference of diagrams and models in two files, click [Open Compare Diagram] button.How to compare models
[Merge] does not work for the following diagrams. Ones in you chose at step.5 will stay.
All the model elements you create in Astah System Safety will have ID internally – we call this “Model ID”. When you merge files, Astah will look into the Model ID and merge the model elements if they have the same Model ID.
When you clone your .axmz files, the Model ID will not be regenerated so it uses the same ID as the original file. In case you merge a file with another file that was created by closing the original one, you may want to reset Model ID of one file to prevent the unintentional result.
To reset the Model ID, go to [Tools] – [Correct Model] – [Reset All Models’ ID].
