Astah Professional offers “expressions” that help you customize your layout and design. This makes your working environment friendlier, and improves the clarity of communications. Expressions include use case descriptions, alias names for models, font settings, customizable icons, mini icons, highlighter/marker pens, and free writing tools.
Export and import in various formats.
Export the diagrams you create in Astah Pro to a variety of formats, including image files (jpg, png, emf, and svg), RTF documents, HTML, Entity Definition Report, and XMI. You can also copy and paste into Microsoft Office documents and print with customized settings.
