  • How can I increase the performance of Astah?

    The performance level of Astah depends on the RAM capacity of your machine.
    Try the following methods if you have not tried them yet:

    1. Use the latest Java environment

    Refer to the How to use a specific version of the JavaVM and use the latest version of Java. 

    2. Hide title bar (Mac only)

    If you are on Mac, hiding title bar seems effective in some environments.
    Go to [Tools] – [System Properties] – [Diagram Editor] and take the tick off for [Hide title bar of the Diagram Editor (Restarting Astah is required)] and restart Astah.
    Hide title bar from diagram editor 

    3. Change Look and Feel (Mac only)

    If you are on Mac, changing the look and feel may work.
    Go to [View] – [Look & Feel] and choose one except [Mac OS X].
    Look and Feel 

    4. Turn off the mouse cursor tracing option

    In some environments, having this option on will make rendering slower. 

    5. Tune some garbage collection settings

    When the value of INITIAL_HEAP_SIZE is set to 16m, the garbage collection does not work fully unless your computer uses more memory than 16MB. 

    To tune up, please change the -Xmx size by following the instructions here:

    If you are on Windows
    Open astah-uml.l4j.ini file which is located in Astah Installation folder with text editor and change the heap size
    (e.g) -Xmx1024m

    If you are on Mac
    1. Go to Application folder and right-click on “astah uml.app” and select [Show Package Contents]
    2. Open [Info.plist] file you can find under [Contents] package
    3. In this file, will find the following lines. Change the -Xmx value.
    -Xms16m
    -Xmx768m

    If you are on Linux
    Open /usr/lib/astah_uml/astah-uml file with a text editor and modify the JAVA_OPTS=”-Xms16m -Xmx384m” line. 

    6. Use the latest version of Astah

    Download the latest version from Download page. 

    7. Hide Map View

    Please follow the instructions here. 

    8. Hide Alias View

    Please follow the instructions here. 

    9. Disable Content Assist and Suggest Feature

    Disabling the Content Assist (A dotted green line that appears on the diagram when you try to move and align objects with others) and Suggest Feature could increase the performance a little. To close, go to [Tools] – [System Properties] – [Diagram Editor] and take the tick off two options.

Functionalities

  • Does Astah Support Object Diagrams?

    Yes. Please create Object diagrams using the Class diagram.
    Please use [Instance Specifications] and [Link] are on the Tool Bar of Class Diagrams.

  • I copied objects but when I edit one, the change applies to the another.

    In that case, Clone the model instead of copying. A cloned model will be an independent model.

  • My Astah file does not open.

    Astah project files (.asta) are upward compatible. If project files have been edited by newer version, they cannot be opened in older version of Astah. For information about model versions, click here.

    If you cannot open project files using appropriate version of Astah, please change the stack size in the [Tools] – [System Properties] – [File].
