Yellow lines represent the model size in the world/map.
A funny way of putting it, it's like wearing a cardboard box in real life.
For example if the yellow lines are too tall above the model like for a NPC they can't walk under a door etc.

hey, I had a question about your hitbox addons, what do the yellow lines represent? I know that the blue lines are for the hitbox.

Hey, could you fix the Enabling and Disabling in the Doors Hammer FGD? I haven't been able to work on my map because I want to add portal doors that can appear and disappear first.

Hey dude I have a crap ton of extra s&box keys and I'm giving them out to Gmod creators. Any chance u want one?
