Is there a way to automatically model walls so they don't join?

[jj mac]

We would like to model a wall, such as a fire wall that has the ability to refuse an automatic join. These wall types should have the ability to heel to each other, but not to walls that do not qualify as fire walls. The obvious manual way to do this is to disallow the join from the walls intersecting the fire walls.

The goal here however, is to be able to automatically show the join conditions of fire walls and regular partition intersections modeled as if they were really being built - with the drywall shown as a continuous element on the wall. This will also help to avoid the drawings being misread in the construction phase as being continuous elements, although the wall tags and schedules will clearly indicate that the wall is a fire wall.

I have almost accomplished this by messing around with the wall functions and changing priorities of layers etc, but it's not 100%. Please see attached.

If anyone has some tricks, I'd love to hear it!

Thanks in advance!

Not as far as I know. I've had a similar situation (partitions abutting a basement retaining wall) and the only solution I found was to disallow wall join and align the ends. God help you if your abutting walls don't meet at 90 degrees though!

Just wanted to check to see if there were any new updates on this issue. I couldn't get a fire wall to maintain a continuous layer automatically, even after setting the "function" of the abutting walls to "core boundary" and "interior" and placing the drywall layers of the fire wall in the structural (as opposed to finish) layers of the wall. Oh well.

Revit 2016 R2 provides an option (Options Bar) while sketching walls, to preset their join behavior, either Allow or Dis-allow join.
