In AC17, I've set up a material with a vectorial hatch attached to it (symbol fill type). I've attached this surface to a slab. When creating a 3d document with this slab, if the document is created from a perspective projection, the hatch will show up in the document, however if a parallel is used to create the 3d document, the hatch will not show up.
Both 3d document settings are the same, set to show vectorial 3d hatching. And there's no differences in in model view options or structure display.
What's going on here?
