I'm having an issue with a split region wall's foundation.  I've split the wall so that I can have the CMU portion of the wall extend beyond F.F. level.  However when I bring the material I'm not interested in extending back to the finished floor level it creates another foundation (see attached image).

Any ideas on how to get around this? I could use a filled region to draft in the foundation or create an additional wall for the footing, but it'd be nice (and cleaner) to use the same wall.

Thanks in advance.

Read up the help files with regards to wall construction, you can specifically create a wall to do as you want, for example, I've used a wall where the Gypsum wasn't attached to the top, and thus I could ensure that it was showing the proper height per code above a ceiling for a fire rated wall.  To do this, edit your type properties for the wall, go into the construction editor, make the section preview show up, click on the desired layer, and if you notice at the very top, there is a lock, unlock this lock by clicking on it, now that layer(s) is/are variable in height and can be dragged to the correctly desired height without changing the wall's height, etc.

Thanks for the quick reply.  However, I understand how to edit a wall so that certain layers can be different heights, what I'm having a problem with is when I make the bottom constraints of the layers at different heights it wants to put a foundation at both the levels.  The image I attached is a single wall with the gyp pulled up from the bottom of the CMU, when I place a foundation at the wall, it wants to put one at both the bottom of the CMU and the bottom of the GYP.  Any ideas?

Here is a link that thetabest is talking about

This is a pretty cool tool, you can make a stacked wall look alike (not a true stacked wall) using the region tools.  Sometimes stacked walls have trouble joining properly so this is another technique.  Not what you asked but it was on my mind.

@Cadman -> Thanks for the backup

@jonesstudioinc -> Sorry, was starting with the approach you'd want to go, now knowing that you have done this, and knowing that the gyp is what is causing the issue, just remove the gyp from the wall construction, and place a new wall on top of this one built with gyp, or do as I did for my basement walls, I had a 5/8" layer of gyp as its own wall, and thus the footing only attached to the concrete wall.  I've found in Revit that sometimes its easier and better to have several walls combining into "one" wall, vs the more complex approach of actually constructing it in the wall.

So to summarize, remove the gyp from the equation, footing should now work correctly, then either place a new wall on top which has gyp built into it, OR make a wall which is nothing more than gyp and abutt it to the wall which has the footing.

Figured that'd be the way I'd have to go! Thanks for your help!

I'd agree with Trent, often it is better to place two or more separate walls when you have differing surfaces, like tile for showers, and the like. You may also want to check the depth of the cut view. I have looked at a section before and wondered what is that. All to find out that the depth of view was more than I needed and was showing information in the distance that was confusing the issue.
