Custom measurement allows you to define and execute custom measurements tailored to your specific requirements.

The Both, Before or After buttons are meant for:

• Both: you can draw on either the before or the after, because both of them are activated.
• Before: custom measurements are only applicable to the before 3D image.
• After: custom measurements are only applicable to the after 3D image.
  
  

Select and define the type of measurement to draw and calculate:

• Straight Line: Measure distances between two points accurately.
• Projected Line: Project lines onto surfaces or objects for spatial analysis.
• Freehand: Draw organic shapes or lines for customized measurements.
• Volume: Calculate the volume of specific regions.
• Angle: Measure angles between lines or surfaces within the simulation.
