I wanted to ask advice of the community on the pros vs. cons of applying a cast stone cornice to a wall comparing adding the cornice profile to the wall after the wall is placed, or adding it to a complex wall assembly as part of the wall.

What do you suggest and why?

(see attached image)

thanks,

Jeff

If it were me I would like to see it as a part of the actual wall that way once you have it created you dont have to mess around with placing sweeps to get the profile you want on the top of the wall.

I prefer to add these in place rather than as part of the wall. 

Some wall defined sweep problems:

1. Sweeps in the wall can not be controlled independent of the wall. 
2. In plans, they can not be turned off. 
3. If the wall ends with a rake angle - like a sloping roof - the sweep is not cut at an angle but is cut square at its shortest point.
4. These can only be horizontal

In place sweep advantages:

1. Can be controlled separately from the wall.
2. The ends can be adjusted.

Disadvantage - they are always horizontal.

In place roof facia advantages:

1. If sketched in one sequence, they will miter correctly at every corner.
2. They can be controlled separate from the wall.
3. They will even angle at rake eaves.

Maybe a better option in some cases is the in-place family sweep because it can go at any angle.

Thanks to both for your quick replies.

WWWHub, a question back to you. Are you suggesting that there is a third way; in place roof facia? I'm not sure how you would do that given the parapet condiion in the image I attached. Would you mind clarifying?

thanks,

Jeff

There are lots of "games" you can play in Revit.  In most cases, I suggest you don't use these tricks but they are available.  Obviously in your case, your cornice should be related to the wall and a wall hosted element would be your best choice. 

I suggested the roof facia solution primarily for conditions where you might have sloping roofs and gables.   But yes, in your case, you could use a trick but I would not recommend it.  It is just something to talk about and expand your knowledge.  Roof facias can be set up with offsets. In addition, the profile can be defined anywhere in relation to the origin in the profile family.  So, you could use the edge of the roof behind the wall to place a cornice on the wall.  DON'T DO THIS!  Just fun to think about it.

Understand..?
