The JustMeasure interface is divided into several working areas.
Top area
The top area contains project controls, file loading and saving, export and basic application controls.
Workspace
The source image is displayed in the center. This is where perspective correction, calibration, helper geometry placement and measurement take place.
Tabs
Each source can be opened in a separate tab. You can quickly switch between drawings without opening multiple separate files.
Tool panels
Tools are grouped by purpose. Some advanced tools are available only in the PRO edition and are marked with a PRO badge in the help.
