I understand that there is a "display curvature function" under the "Evaluate" tab. However, I am unsure of what is the exact kind of curvature data being displayed on the curves. Is there a way to set the view mode to display the curvature data in the form of "Gaussian curvature"?

Also, is it possible for SOLIDWORKS to export the curvature data of each point into something to the likes of a .txt or excel file for further processing using other softwares like MATlab?
