FreeCAD's Blender Interop Workbench demonstrating the Solidify modifer om a complex shape

This video is created to demonstrate that the FreeCAD's 3D offset operation fails, where the Blender's Solidify modifier succeeds. In this demo a mesh from an actual 3D scan was taken. And to give FreeCAD a fair chance, the imported mesh was already 'remeshed' (using Blenders remesh modifier manually).
