Interface Theme Update

Continuing the interface design objectives for all HydroComp’s tools, NavCad 2025 now sports the main toolbar design first introduced for PropElements. Principal event buttons are collected and organized into Project, Components, Simulation, and Results groups. Our priorities are to maintain NavCad’s well-known and efficient workflow, but to also find aesthetic and process improvements that users expect with current versions of Windows.

Hull CAD import workflow and rendering

The hull CAD import module has been moved to an integrated docked page for better ability to view the hull geometry, as well as the data extraction attributes and features (e.g., cutting planes). A new rendering library has also been employed for smoother visualization and aesthetics.
