Draw UML Diagrams Faster Using Our UML Specific Features

Why Drawing Flowcharts is 3 Times Faster with Creately

Drawing UML diagrams with Creately is basically a cakewalk because of its unique UML features. Say for example, you are drawing a class diagram; when you connect two objects, our smart connectors automatically detect that it’s a class diagram and from the drop down that shows up, you can select the relationship of that connector.

And with our text to shape feature, you can modify and format various UML objects exactly the way you want them to by simply changing the text within the container. Powerful features like this really make UML diagrams more fun and more productive.
