Curves above Objects become hidden

I can’t seem to figure out what’s happening here. Any curve that overlaps a geometry on my viewport becomes hidden on the Shaded view. Meanwhile, changing the display mode to Arctic shows another weird behavior. Curves go through Polysurfaces on Arctic view similar to a wireframe viewport.

I’ve reset all display modes to default and the issue still happens. I also tried copying the geometries to a new file and the display issue still occurs.

What could be causing this? Thanks!

Is your geometry far away from the origin? This can sometimes cause display issues like this.

No, the curves are either coplanar or above the objects by a few millimeters.

Hi Thomas - I do not get this effect here, but the curves do have draw order applied - it might be that ClearDrawOrder first, then, if needed, apply BringToFront etc will sort things out.

Hi Pascal, thank you for mentioning the draw order. I accidentally applied BringToFront sometime before which caused the curves to go through geometries.

ClearDrawOrder fixed the issue.

Thank you so much. I’ve been bothered by this since yesterday.
