HFSS save options: "Save preview images in project file"

Hi

Could anyone say what this option does in HFSS : "Save preview images in project file" [picture attached]

Dear rizoeda,

This save preview images option will help us to show the our model image as a image when you open the old files. Try to open by saving the with enabling and without enabling the two files. When you try to open the one you enabled will show the preview of your model other one cannot show anything.

Thank you sree479.
