Very odd. Using 2018, the original object Shelled to -0.03, but TurboCAD crashed when I tried to save the file (didn't even drop down the File sub-menu items); this happened both times.
Re-starting the first time got a Windows Compatibility popup. And the Open Last Edited option referred to an earlier file (but clicking on Open File defaulted to this file).
Third time was the charm, but I used the mouse to open the File / Save As requester instead of my usual <Alt> Menu selection method, so that's a bug of some sort.
Attached is the file after I 3D Sliced the object. It failed when I V-snapped to the outermost vertices, so I manually clicked just below that vertex in Front view to get this result.
