The update Software Ideas Modeler 15.20 brings a major platform upgrade along with workflow improvements and important stability fixes. This release focuses on modernizing the underlying runtime, improving diagram layout consistency, and refining navigation and processing in complex projects.

Platform Upgrade to .NET 10

Version 15.20 moves Software Ideas Modeler to .NET 10, ensuring better performance, long-term platform support, and improved compatibility with modern systems. This upgrade lays a solid foundation for future development and enhancements across the application.

Harmonize Diagram Layout

A new Harmonize Diagram Layout feature helps bring visual consistency to your diagrams. With a single action, element placement and spacing can be aligned more uniformly, making diagrams clearer, cleaner, and easier to read—especially in large or evolving models.

A new setting Skip Connectors in TAB Navigation gives you more control over keyboard-based navigation. When enabled, TAB navigation focuses only on diagram elements, allowing for faster and more efficient selection without unnecessary stops on connectors.
