Weird Shading/Normals Issue

[Anonymous]

I've been working on a simple wine glass model and right when I thought it was finished, I noticed that there are some issues with the shading on it, so I tried fixing smoothing groups. That didn't work, so I checked out how the normals looked and I'm not sure if they're correct. I tried a ResetXForm and also tried unifying the normals and that did not work. My knowledge of how to fix this issue is stretched thin, so I figured I'd look for help here. I've attached the scene file if anyone wants to take a look.

OK, you have multiple issues in the dwg that are creating the appearance you see in the viewport - after downloading your file this is what I did to give you the proper view of the shading and geometry of the glass:

1) go to viewport configuration tab ( views - viewport configuration ) select the lighting and shadows tab and use 1 light and unselect       hardware shading box.

2) In the upper right corner of viewport where it reads [ smooth + highlights ] click on this and select edged faces also.

your wine glass should look Great ( at least normal )  Let me know if this works for you -

Yep, this worked; the model looks fantastic now.
