"Tip of the year 2007" fade out in elevation from Revit model

Joe Zhou from our Hong Kong office says - "this tip provided by Kei from Autodesk helped us and is so good I want to let everyone know about it"

This tip is useful especially in Scheme Design stage when you want to create fade out effect in elevation sheet. Here is the procedure to achieve 'half toning' far side elevation view overlapped on regular elevation view both layout on same sheet

Create two elevation views:

1 - Farside clip just about enough width (does not need to be accurate) that will appear on specified elevation view angle.

2 - Foreside with thin layer of depth clip, but having overall width for ground surface. (This is for better performance + not to show farside objects)

3 - Place them on sheet in order: Place farside first

4 - Then, place foreside - when placing this view, you should be getting center of gravity ‘cross reference lines’ for accurate location (placement order matters for foreground/background. See elevation image above, farside is overlapped by foreside without trimming at right edge.)

If you happen to place foreside first then the farside, delete foreside then replace it.

Kevin Parks says: Another way to accomplish the same thing is to select the objects and use "override graphics in view" to halftone the objects.
That way you don't have to mess with multiple views.

I've posted another option for this here: http://bimmanager.blogspot.com/2007/12/shading-elevations-in-revit.html

Tip of the year??? Yikes.

Though it was previously stated I will reiterate: The recommended method to accomplish this is with "override graphics in view"...this way you can have many overrides for many object(s) not just an overall greyscale!!!

Composite views are useful and fun but in this case I think they are a waste as well as inflexible!!!

Use Revit like Revit.

1) initially we're trying to use "override graphics in view" by selecting the objects as mentioned by Kevin, but this is very limited as too many objects in our project's elevations are spanning across foreside & farside, but this is the best method if foreside & farside objects are relatively isolated.
2) David's method is cool but this will increase "modeling" overhead, besides, this seems a bit distance from Revit's whole "idea", but this is the best method if more levels of fade out effect are expected.
