I've got a strange issue with my project: every wall has good intersection and don't have any line out of place while modeling. But as you can see in the image, when I publish any PDF there's some strange line between them.
I suppose it's generated by the "Clean intersection" but I don't know how to fix it.
I've tried with different color palette but it doesn't make any difference.
Thank you in advance to anyone will reply or help me
