How do I get rid of these dark lines on transparent glass?

[Cadxsan]

Why isn’t this transparent dark line disappearing? I have already tried making it a union, changing the material to glass, exporting the union as a mesh, and I even checked if there was a gap in between the 2 parts. There was no gap, but the line does not disappear no matter what I do. Is there a way to get rid of it?

How to get rid of dark lines between trancparent parts?

Okay, your problem is that the parts are not correctly lined up against each other: one part is too thick, one part is too thin, some parts are overlapping, you get what I mean. So I suggest that every part should have the same thickness, do not overlap the parts with each other and just line them up correctly then “unionize” them so it has that smooth and clean look.
