You can launch Astah by:
When launching Astah, it automatically looks for new updates through HTTP access and shows a dialogue if a newer version is available.
If you wish not to check for updates, change the option from [Tools] – [System Properties] – [Other].
If a license is not set up yet, a license dialog appears when you launch Astah.
You can open this dialogue from [Help] – [License] anytime.
If you have a floating license, click [Set Floating License]. For further steps, please read the floating license guide.
If you have a non-floating license, click [Set License key] and specify your license file (.xml).
A free 20-day trial is included at the first installment. Once the first 20 days are over, please purchase a license.
When you start Astah for the first time, you may get this blank screen.
But when you create a project or a diagram, all the panes will go active as below:
Project View provides an overview of the whole project. Tabs at the top can be used to switch the Project View between “Structure Tree”, “Hierarchy Tree”, “Inheritance Tree”, “Map”, “Diagram”, “Search”, and “Alias” views.
The Structure Tree is the default view in this Project View where you can see the structure of your project in a hierarchy. You can organize diagrams and models using packages.
Simply type a keyword, and hit the [Enter] key. The *, ? and camel cases are available.
You can filter by specifying the model type. If you want only Classes to appear in the tree, hit “type=class“.
You can also add a keyword to filter by its name too. (e.g: type=classEngine)
This shows Classes only and the following keyword works for Classes only.
This shows Packages only and the following keyword will work for package names only.
This shows [ER] package and models under the [ER] package and the following keyword will work for ER models only.
This shows diagrams only and the following keyword will work for diagram names.
When a model is used in other diagrams or in the same diagram within your project, you can find where they are used and jump to the specific model.
Map View is a controller of the diagram view. The yellow rectangle indicates the area that is currently shown in the Diagram Editor.
You can drag the yellow rectangle to change the area you want to see on the diagram editor.
You can create a yellow rectangle by a right-drag to pinpoint where you want to see.
If you do not need an independent map view, you can hide it.
