In most models “seams” show where they aren’t desired. I’m posting this on this forum because I’m relying on Hidden view, which I believe is specific to Va.
Here’s a corner in shaded and in Wireframe view. No 90 degree “seams” on the face of this door frame corner. (There’s no diagonal seam either, but every solid display mode erroneously shows those - let’s focus on the unwanted 90 degree seams.)
Here’s the rendered view with its display settings:
But here in the Hidden view (please note its display settings also) there they are, as they are in most every door frame I model. (This door frame happens to - unrealistically - wrap around a curve, but this issue happens with orthagonal door frames also.) Can I get rid of these things?) They are interpreted as an undesirable decorative feature.:
