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].
When a license is not set up yet, a license dialog appears. You can open this from [Help] – [License].
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:
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.
