I’m trying to use the “slab edge” tool in Revit Architecture 2011 to create a brick ledge with an exterior grade beam that will be accurate in elevation and any section that I cut. Since the “slab edge” tool is based on a profile, I created a profile with the desired shape. When I used this profile on a slab that went all the way out to the face of the exterior wall the slab covered up the brick ledge I had created in the profile. I then went and offset the slab the width of the brick ledge and adjusted the placement point of the slab edge profile. I also created another profile that did not have a brick ledge for exterior doors and adjusted its placement so it would be flush with the profile that had a brick ledge. All seemed to work fine until I extended the brick portion of the wall down into the brick ledge I created. Now the brick shows up below the door in elevation and in section. Editing the wall profile doesn't work either because the location where it needs to be edited is where the door is being hosted.

I also wish the profile could also be parametric that way I could adjust the “slab edge” per project specifics (ex: grade beam depth/width, brick ledge depth/width, etc). I tried creating a component to add to the slab that was fully parametric but even though it worked it seemed to be a much more cumbersome way of approaching it when Revit has a built-in tool.

Is there a better way to create an accurate brick ledge that will show up in section?

Any help or suggestions would be appreciated.

Have you tried to create a VOID geometry (in-place) to create your brick ledge? That might work. I'm sure others have done this in different ways....

Have you tried creating a foundation wall with a parametric ledge where you specify the depth of the ledge in the properties? I used this to create a slab ledge for a garage floor, but this same wall could be flipped to use as a brick ledge.

Create a new concrete wall type with two 4" walls, while you're in the "edit assembly", click "preview", "modify" (make sure you're in section view), then zoom in on the top, select the top of wall line and unlock it. This will allow you to edit the "top extension" offset under constraints in the properties after you've drawn the wall. You would have to create a new wall for every thickness though, and then use linework to hide the line between the two walls.

 Being an old post, have you figured out a good way to do it yet?
