When set offset to 0.008, the edge of my dresser turns wierd in Blender 2.82?

Hi Community,
Any idea why when I turn my edge of dresser to 0.008m at the offset. My dresser will show this strange looking thing?

Thank you.

Hey there

My guess would be that Offset value is simply too big for what physically possible. If your edge is thinner than 0.008meters than this will cause overlap (Clamp Overlap checkbox automatically prevents that by clamping the offset at a value before overlap can occur).
Don’t forget to apply scale to the object (especially if it has a non-uniform scale) to get predictable results.
