When you start Astah Professional or UML for the first time, you may get this blank screen.
But once you create a project or a diagram, the left pane will open:
Astah Professional and UML consist of six sections:
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 or referenced in multiple diagrams in your project, you can find where it is used then you can jump over to the location. There are two ways to do so.
Open a list of diagrams
Open diagrams as thumbnails
Map View is a controller of the diagram view. The blue rectangle indicates the area that is currently shown in the Diagram Editor.
You can drag the blue rectangle to change the area you want to see on the diagram editor.
You can create a blue rectangle by a right-drag to pinpoint where you want to see.
If you want to change the location of the Map View, you can change it from System Setting.
If you do not need a Map View, you can hide it by clicking on [-] button on the Diagram Editor.
[Diagram] view shows a list of all the diagrams in the project file. You can sort this list by its name, diagram type, the model type and also packages where the diagrams belong to.
You can open the diagram or jump to where the diagram is in the structure tree from the context menu of the diagram in this list.
In this Search view, you can search models and diagrams within a project.
You can use search options to access the specific models or replace strings, and clean up the project by finding unused models or broken hyperlinks…etc.
You can filter out models that are not on any of the diagrams or referenced by any other models and also find broken hyperlinks.
To learn more about Search features, please read this guide.
Dark theme is available since version 9.0. To change the theme, go to [View] – [Look & Feel].
After changing the theme, you will need to restart Astah.
