I spent a fair amount of time creating weld beads in an assembly model (and learning the quirks thereof). In my drawings I want to add a shaded isometric view. However, the weld beads are not showing up. How do I get them to appear?

While we're at it, how would I represent the beads in the 2D views? Is that what the "caterpillar" symbol is for. How is that used? (This is the first drawing I've done with significant weld representation."

Thanks
