So, there is a drop down under View Properties for DISCIPLINE.
I have NEVER been able to find proper and complete documentation about what gets turned on and off in your view when you change this. We are learning by trial and error, but why oh why is there no list simply indicating what each of these shows.
Do a Google search on it and you’ll find people getting confused why their walls aren’t showing up, or why the hidden lines in ductwork suddenly goes away.
If aynone has a list, please point me to it. Otherwise I’ll continue mentally documenting things that disappear when we notice them.
