You can create annotation points, Min/Max annotations and show/hide annotations for Thickness colormaps, similar to Surface Colormaps.
When you create annotations for a Pointcloud or Mesh data object (not compared to a CAD model), the annotation shows the measured thickness.
When you create annotations for a Pointcloud or Mesh which has been compared to a CAD model, the annotations show the thickness deviation between the measured thickness and the CAD.
