Revit Architecture: Allow and Disallow Wall Joins

One of the best features of Revit Walls is their ability to automatically join with each other. No more manually trimming and extending wall layer lines in AutoCAD! Just place your wall segments into your model and let them automatically resolve the junctions between their various layers. The image below shows a typical join between two wall types…

You will note how the outer layers (plaster) of the internal wall automatically interface with the the plaster layers of the external cavity wall. In most situations you do indeed want Revit to automatically join one wall to another. But what about the remaining situations where you simply want to butt one wall up against another and “not” have them join? Thankfully in Revit, we have the ability to toggle the “auto-joining” behavior on and off.

If in our above example we do not want the internal plastered wall to auto-join with the main wall, we simply do the following…..

First of all select the internal plastered wall. Once selected you will notice a blue grip a small distance away from the end of the wall. For clarity, I have pointed towards it with a green arrow in the image below…

Go ahead and right-click on this grip. This will bring up a floating context-sensitive menu. Near the top of this menu you will see the option to Disallow Join….

Go ahead and select this. Upon deselecting the wall, you will see that the two walls now simply crash into each other and make no attempt at all to resolve their junction…

Go ahead and select the internal wall again. You will see the blue grip that you just right-clicked on….

Now you can simply drag on this grip to place the end of the wall exactly where you need it to be. For this example, I’m going to simply butt up the internal wall against the plaster face of the cavity wall….

Notice how the inner plaster layer of the external cavity wall remains continuous- with the inner wall simply butting up against it. A typical example of where you may wish to disallow joins would be for toilet cubicle partitions- you would want them to simply butt up against the wall of the room they are in. At any point, you can switch back to auto-joining your wall, by right-clicking on the grip and selecting Allow Join.
