The Properties panel is opened through the main upper toolbar under 'Tools > Properties'.
The Properties panel reveals 'File Information' for most items that are selected with the mouse.
Some items such as scans, folders, and piping components will have a few adjustable property values. A scan file, for example, can have its transformation manually changed by making changes to its 'Scene Node' and 'Scene Position' values.
