Here’s the fill situation (not this particular post but the entire thread):
As to line attributes, it’s just too overwhelming to attempt to find a display representation which removes hidden lines, respects line weights by layer, shows colour tone on particular objects, renders proper fill patterns on sectioned Va Objects, prints with sharp vector lines, and sometimes enables transparency and sometimes renders dark tone to distinguish glass panels on windows. I have taken to using a Va Section View superimposed over a shaded 3d view with glass objects SetObjectDisplayMode to Rendered. It’s cumbersome.
