OT since two people have asked why we have reference lines: Reference lines are critical; do take the time to understand how they are used and can be used.
The reference line for a wall, for example, "anchors" a space-critical surface of the wall (your choice of what you deem space critical). Frequently, the reference line might be the exterior structural face of a composite or profiled wall. By placing the wall with the reference line there, you can change the entire assembly of the wall and still have the structural, bearing volume of the new structure aligned at that position, all in one step by selecting a new wall type. The exterior skins may grow or shrink. The core(s) may grow or shrink, and the interior finish skins can grow or shrink, but the entire structure will align as intended - e.g., outside face of bearing core to outside face of bearing core below / outside edge of slab below, etc.
Also beware when you are making new composites. There is nothing to indicate which side of your composite the reference line will be on. The reference line of the composite will be at the top of the window where you assemble the materials. Knowing this may save you the trouble of having to reassemble your composites to be consistent with what has been arbitrarily designated as inside or outside in some other place.
Steve, are you talking about ArchiCAD 17 here? Or previous versions.
The reason I am asking is that the whole Reference Line, plus Left/Right/Center method of Wall placement is overhauled in ArchiCAD 17. So you always know what is the Outside and Inside of the structure and it does not change when modifying the Reference Line Location.
Yes. 17. The overhauled method and arbitrary designation of what is Inside/Outside is something that not only works a little different in 17 but also may preclude the way some ( perhaps only me ) were using the Reference Line before. This is not the best thread to get into the details about that. Which is why I was just offering a word of caution.
Having more Lines of Reference ( I would call them ) and tools to manage them, may compromise the ability of the "Reference Line" to proved a single and consistent frame of reference for both spacial and material orientation. The solution I was hoping for would have taken into account the main reason we need a single and always consistent frame of reference in the first place. Openings. It's the language and terms that are being used that needed the over haul. Not the Reference Line.
If you are using terms relative to the Reveal and/or the Reference Line the need for ambiguous terms like Inside/Outside are irrelevant.
This does not mean there would be no need for more "Lines for Reference" in Composites.
