I’m having some issues with lines and surfaces that appear when my geometry intersects with clipping planes (see screenshot). I’m using an own display mode (duplicated from the pen display mode) and trying to make a 3D section. I’ve changed section styles in the layer panel (added hatches, determined lineweights).
Thank you for trying to help. The residual lines do appear when I use the standard pen display mode as well, they don’t when I use shaded for instance. Moreover, I’ve noticed that they’re not only appearing when objects hit clipping planes, but also in regular geometry a lot of extra lines appear (see image below). I’ve attached the 3dm file in the link below.
