Inter-page linking

Elements in a drawing can be linked to a specific page in the same document. This helps the user define the UI flow when creating an application or website mockups.

Linkings defined in a document are converted into HTML hyperlinks when the document is exported into a web format. This process creates an interactive version of the mockup in which viewers can see a simulated flow when clicking on the UI elements.

The predefined objects can be added into the working environment using “drag and drop” operations. Plus, you can move the shapes to any area of the workspace, undo or redo your actions, align the objects, lock an element, perform basic editing operations (cut, copy, paste), and resize the canvas.

The tool offers support for connectors, which can be used to wire shapes together in a diagram. Additionally, you can links elements in the drawing to a specific page, zoom in or out, and customize the text in terms of size, font, and location.

Exporting options

The tool enables you to print or export the generated design to PNG, PDF, SVG, or ODT file format, use hotkeys for better control over the entire process, switch to a full-screen mode for a better focus on your work, group, or ungroup shapes, as well as make the objects the same width or height.

Last but not least, you can install a new collection of shapes, provided that the file format is EPC or ZIP, and use the clipart browser tool that integrates with OpenClipart.org to find clipart and add them into the drawing.
