Wall Jogs and Tough Clean Ups

UPDATE – Please check out Bjorn’s quick and easy technique in the comments.  It’s one of those things that makes you say “no way!”  You still might need to do some “dancing” with some elaborate stacked walls, but the below tip is an excellent first step that should resolve a lot of the issues.

There comes a point in any Revit wall’s life that it just cannot clean up.  It’s not when the wall is too big, Revit LOVES big.

It’s when it gets too small.

Look at the below two wall strings.  Go ahead, I’ll wait.
Still waiting...
All set?  Great.  Now, they look fine, right?  Clean up nice and pretty.  But look what happens when I scoot that lower wall in both strings up just 1/8″.

What in the world happened to the wall string on the left?!  That jog got all messed up!  But the one on the right is fine!  What’s happened here?

Well, the overall width on the wall on the left is 1′-1 7/8″.  That’s the key.  Once a jog, or clean up length gets less than the overall width of the wall, the wall gets very confused and mad.  The top two “horizontal” walls are overlapping the lower “horizontal” wall, and making cleanup a nightmare.

Is there a solution?  Sort of.

First thing you need to do is think about how it would actually be built… you know… in the real world.  Would it really be jut the wall walking around this gap, or would it be a different wall type, etc?

From this point, there are a couple options, none of which are ideal.  We have tried them with mixed results.

You can make an architectural column and slap it on the wall.  We’ve done that.  Works… OK.

If you want to use walls, there is a very round about way to try and get these things to clean up.

First we need a frame of reference on our walls.

So, walls 1 and 5 are our major horizontals, 3 is the smallish horizontal, and 2 and 4 are our right and left verticals, respectively.  You’ll see from the above image that I have already started my work. 

The first step is to disallow the join between 2 and 3 and 3 and 4.  On the appropriate end for each wall, you need to right-click on the grip and select DISALLOW JOIN.  You’ll do this for the lower grips on 2 and 4, and both gripd on 3.

Then you need to do some aligning, and you will only figure this out with trial and error and a lot of undos.  For this case I ended up aligning and constraining the left face of wall 3 to the left (interior) face of wall 2 and the right face of wall 3 with the right (interior) face of wall 4.  Then I aligned and constrained the lower face of wall 2 to inside the finish material of wall 3.

The final step is to simply JOIN GEOMETRY on each combination of walls: 2 to 3 and 3 to 4.  And here’s the thing – THE ORDER THAT YOU SELECT WHAT WALL FIRST MATTERS.  In this case, I selected the “verticals” first, so I clicked 2 then 3, and then 4 then 3.  It “feels” like the first thing you select when you join geometry “wins”.  I have zero scientific data to back this claim up, but that’s what my gut tells me.

Poof!  Nice and clean.  And if I nudge or straight out move wall 3 up, the clean up stays with it.

This is definitely one of those cases where no one solution fits all problems but if you know the possible solutions, you can hopefully pick an appropriate response.

  1. This is one that had me stumped for a little while as well, until I ran into a little tip somewhere.

    Highlight the vertical wall (wall 2 and 4 in your pic) that gets too short for Revit and click on the blue grip points once each. That should auto-cleanup your join. Repeat on the other side.

  2. It was not in the help file, I don’t want to take credit for this. Like I said I ran across it somewhere when a customer of ours had severe issues with lightly protruding walls.

    David Light’s excellent blog solved it for me:

    Funny fact was that the guys at the TechCamp 2008 in Paris couldn’t get it to work, I ran into this about a month later.
