Yes. If I understand the question. There is probably more than one way to do what you need. You can make a wall that will display only a line where the reference line is if that is what you need. And you can make that line any type you want.

What your asking about might be the typical 2-line walls of a plan that shows only the core/framing with dimensions only to one edge of the core.
This is a common way to show Floor Plans that the Framer likes to use because it does not show any of the other wall skins that he does not care about. Is that what you need?
If you can show a picture of what you want it to look like I am sure it can be done with ArchiCAD, no matter what it is.
