Here is my dilema. I would like to create a section or an elevation that shows objects farther away from the cut plane getting lighter. Is there any way to accomplish this or do I need to go add this to the wish list area?
Thanks for any help.

No.
You really only have two options. Use the linework tool to individual pick lines you'd like to change the lineweight of (painful and not very good if you still plan on making lots of changes)
OR
Enable shadows (printing time increases but gives the best indication of depth).

Check out the attached pdf. I thought it was an interesting quick fix for this issue.

I like the simplicity of your approach strandcad.

Has any one tried strandcad's method? I am trying it but when I do a plot preview the building behind the glass doesn't show up at all. Using Revit 9.1. Figured it out. Have to be sure to set the raster processing instead of vector processing.

Very good idea! My question is did you make a new object set as glass or make it a curtin wall?

I made it a curtain wall with no mullions what so ever.

the glass sheets are a clever method, just watch your materials schedules or take-offs if you have any! Another way that I read somewhere is to select all the elements you want to appear halftone, type something into their comments parameter (like maybe "west elevation fade" ), then create a view filter that displays as halftone elements with that comment. I guess that only gives you two layers of depth, so it is more limited than the glass method, but it is another way - and one that isn't such a danger to birds.

There is a way that I found works better than using the Linework Tool. It's a matter of selecting "Override Graphics in View: By Element" when you right click a specific element. {Just underneath "Hide in View: Elements"} What I did was change the color of the projection lines. Changing the value in your color by increments of 25 is pretty close to a 10% screening increment. I went ahead and established my own shades of grey in the custom colors (making the procedure a little quicker). This technique seems to work rather similarly to the screening process in AutoCAD. Effectually, it's the same concept as using linework except it it's a lot faster, for me atleast. Edited on: Thu, Apr 3, 2008 at 5:13:47 PM

Another method that I've been experimenting with that doesn't involve using a 3D as an elevation is to get your elevation & crop region setup and limit its view depth, then dulicate it, move this view to cut where the previous view left off and override the graphics for everything to a 75% gray and limit its view depth, and repeat for as many layers of fading you want. You can then overlay your elevs on the sheet, placing the furthest on the sheet first, and if you print with raster graphics the views will obscure each other. You could also thicken the cut line of the 2nd view to provide a silhouette edge around the 1st if you're careful about where you cut. Cheers.

In 2008 and later, you can view, over-ride the graphics of objects - including their surface patterns.

OR you could just mask over the model farther away and change the surface transparency of the masking region.

zfarrell,
Can you walk us through your suggested process? Ive been using Revit and have never seen this. Perhaps it is not a knowledge response.

I'm using Revit 2013.The technique is rather tedious, but gets the job done easily. Under the (Annotate) tab, click the Masking Region. Mask over everything that should be a shade lighter. Complete the mask, right-click it, and go to the Override Graphics By Element window, and change the Surface Transparency percentage. The regions can be layered up, so if you're using two regions on top of one another, both at 25%, the result is 50% transparency.
The only downside to using this technique is that it is view specific and somewhat tedious to draw a masking regions on every elevation, also if the model changes, the masks will also have to be individually altered. But on the up-side, its a quick and effective technique, reccomended for projects in later stages that arent expecting any huge changes. It also does not alter the model like adding sheets of glass would.
Version 2013 has issues with printing "surface transparencies" of model objects, but doesnt seem to have a problem with the detail items. Give it a try and see if it works for you too.
