The solver button changes appearance after results exist. Running the solver refreshes the active results and updates the model choices shown on the canvas toolbar. ## Data Tab The **Data** tab is the primary project navigator. It contains: - **Maps** - **Damages** - **Assets** - **Sources** Right-click a root item to add new objects. Right-click an existing object to edit, rename, or delete it. Double-click an editable object to select it for editing. ## Property Grid The lower-left property grid edits the selected map, damage level, asset, source, or consequence model. Properties are grouped into categories such as **ID**, **Display**, **Model**, **RCV**, **Anchor**, and **Scale**. Fields with an ellipsis button open a specialized editor. Examples include notes, chemical selection, geometry picking, image pixel picking, and damage values. ## Canvas The canvas displays raster maps, assets, source markers, IDs, and solver overlays. The status bar reports cursor coordinates and other feedback. The canvas toolbar includes: - **Refresh** - **Zoom In** - **Zoom Out** - **Zoom All** - **Pick Query** - **Measure Distance** - **Active Model** result selection, visible after a successful solve ![[Images/Main-UI-Populated.png]] ## Message Log The message log at the bottom records file operations, solver validation, solver progress, warnings, and report generation status. Right-click the message log to clear it or copy it to the clipboard.
