Smart Designer: AI-Powered Diagramming
Software Ideas Modeler 15.60 introduces Smart Designer, a new AI-powered sidebar designed to help you create and update native, editable diagrams directly from text prompts.
Instead of generating static pictures, Smart Designer builds real diagram elements and relationships inside your project. Out of the box, it provides strong support for UML diagrams, ER diagrams, wireframes, and mind maps, along with basic support for other diagram types. You can choose a specific diagram type from a grouped menu or keep the Auto option selected and let the AI choose the most suitable diagram type for your prompt.
Smart Designer can work with your existing model context. It uses elements and fields currently selected in the editor, retrieves relevant project context on demand, or lets you manually attach specific diagrams and model elements.
In addition to creating new diagrams, Smart Designer can modify existing content—renaming elements and fields, changing field types, and adding new fields, elements, or relationships. Before modifying your model, a review dialog displays affected elements, any shared diagrams where those elements appear, and clear before-and-after values. Approved changes are applied as a single undoable operation, and generated drafts can also be inspected in a dedicated dialog. You can configure both a primary and a secondary AI model in the settings.
Improved Look and Feel and Modern Outline Icons
Version 15.60 refreshes the application's look and feel with a new set of modern outline vector icons.
Crisp 24x24 outline icons are now used across the ribbon, toolbars, menus, toolbox, and sidebars, scaling cleanly on standard and high-DPI displays in both light and dark themes. If you prefer the traditional appearance, you can switch between Modern (outline) and Classic (colorful) command icon styles in Options at any time.
Improved Color Picker
The color picker has been enhanced to make selecting and fine-tuning colors faster during styling.
In addition to the default palette, it now includes built-in Modern UI and Pastel palettes. A quick footer bar gives immediate access to color shades, recent colors, live HEX input, an eyedropper tool, quick copy, and transparent fill selection, alongside RGB and HSL adjustments in the color mixer.
Workflow Improvements and Stability Fixes
This release also delivers practical editing improvements, better error reporting, and multiple stability fixes.
The Add Multiple tool now respects grid snapping and snaplines when placing new elements on the canvas. Use case flow steps entered as text now support full Undo and Redo, and importing an invalid settings profile displays a clear error message.
Several crash scenarios and export issues have also been resolved—including preview refreshes while editing, element creation or copying after type changes, adding relationship bend points, editing fields and attributes, SVG export of formatted requirements, and EMF generation when copying or cutting elements.
