Starting from Dragonfly 2020.1, you will have the Scalar Information panel for meshes, where an Export to CSV button is located:

While the Dragonfly UI (prior to 4.1) does not have an option to export the thicknesses stored within a Thickness Mesh, here’s how you can do it through the Python console :

- open the Python console (main menu, Tools->Python Console)
- type this:

m =

- then drag your mesh from the Data Properties and Settings panel and drop it on to the Python Console
- press enter
- m now contains your mesh
- type this:

d = m. getVertexScalarValuesAsPandaDataFrame()

- pressing enter after each line. Note the double slash used in the file path

You’ll then have a csv file of the thicknesses.
