Layout & Drafting: What's the plan?

Unfortunately, not. Maybe it might work for small scale of project like housing. However, usually more than thousands of elements are created in a architectural project. It doesn’t make sense to set section attributes one by one whenever a new object is created. It will slow down work significantly.
Actually, I thought a Rhino 8 new feature, Section Style will be able to support different attribute for projection and section. However, it’s just hatch style. I don’t know why Mcneel call it ‘Section Style’.

Another problem with working on drawing through Rhino is to make model space get messy. 3D model and 2D drawings should be created and managed in a different space or in a different viewport so that model space does not get messy. Unfortunately, Rhino does not support different layer state setting for each viewport. If it will, we can see a only 3d model in a viewport and only 2d drawings in another one. This method will make it possible to manage drawings more efficiently.
