Walls not joining correctly with both walls with a base extension distance

[sam_harders]

I am getting an issue with Wall Joins and base extension distance

like this previous issue mentioned
https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Base-Extension-Dis...

i am using revit 23 and what is happening is exactly the same

currently i need to update every join manually to mitre

I have seen this before and there are a couple of workarounds there but just to make sure we are not overlooking some obvious Revit traits.

Are they placed with "Disallow Joins"...select the wall and click the T sign to re-allow Join

Are you using Unlocked Layers with Base extension?.... On the Ribbon

1. go to Modify >> Geometry >> Wall Joins
2. Then hover over the Corner >>> click to select >> Change to Mitter 

Or Alternatively:

• Disable Join on one wall only
• Stretch wall to allow Geometry to Join following Layer function

NOTE: If you disable Join on both walls >>> You will need to manually invoke Join Geometry tool

Hey Thanks for the Reply

They are not placed with "Disallow Joins"

yeah i have the brick and cavity unlocked while the stud is locked. so it works with out slab drop down. 

(have tried only brick unlocked but has the same issue)

Yeah i know i can update every join manually. but i shouldnt really need to do this. 

In my original post i had a linked issue report from Revit 2016 with this issue. 

So i assume its just a bug and i will need to do this workaround until its fixed. Hopefully dont need to wait another 7 years.
