Hidden Lines not Wider than Category

In Object Styles (or Visibility/Graphics), the Structural Framing Category, Projection Line Weight is set to 4. This means that the Hidden Lines Subcategory cannot be set higher than 4. Actually, it can be set higher than 4 but will not display higher than 4. 

Structural Framing Lineweight not Changing in Section

Imagine you have a Girder and a Joist as defined by Revit. You would like the Joist to be a thinner lineweight than a Girder, in every view. Not possible by default. Changes to the Subcategories of Structural Framing in Object Styles only affect plan, NOT SECTION. Subcategories of Windows, Doors, Wall Sweeps and other objects are affected by changes in Object Styles, just not Structural Framing. How do we work around this programming error? Edit the Structural Framing Family, make a new Subcategory, Assign the geometry to this new Subcategory. Now in the Revit Project file, open Object Styles and edit the lineweights of the new Subcategory you just made.
Anyone know why this is the way it is? Anyone have a better workaround?

Revit and Landscape Design

When asked 'does Revit do Landscape Design?' some will immediately say 'No!'. They are quick to point out it's 'limited' site tools. But I think we need to ask 'limited compared to what?'. AutoCAD doesn't come close to the overall drafting efficiency that Revit provides. Plus, AutoCAD has no automated site tools and it's 3D tools are definitely 'limited'. How about Sketchup? Sketchup has a similar 3D toolset to AutoCAD, granted it's graphics are much nicer. Still, both Sketchup and AutoCAD  slow to crawl when dealing with large file sets. AutoCAD Civil 3D is a wonderful tool, it handles large files and has excellent 3D and BIM tools. Civil 3D should be the tool of choice for landscape architects, problem is it's relatively hard to set up and use.

So to what are we comparing Revit's tools? To Revit mostly. All of us in the Revit community have been asking for improved site tools in Revit from day 1. This is mostly because of the potential we all see. Has Autodesk done anything about it? As of today, not much. Yet Revit's 3D and BIM site tools are better than AutoCAD and Sketchup and are easier to use then AutoCAD Civil 3D. So can Revit be used for landscape design? Yes, landscape designers and architects are using this tool around the world with success. Below are some examples:
