"Cannot extend layer(s) of the highlighted vertically compound wall." error

[seutaojiang]

hi I am a new user of revit and I am trying to  unloack brick  layers of the exterior wall (please see the attached image file). But when I open the little padlock and press "ok" button,  Revit gives me an error message:  "Cannot extend layer(s) of the highlighted vertically compound wall."  The walls are not attached to anything. why i get this error meaasge?   How can i extend the brick layer?

Thank you very much in advance!!!

Select all the walls in the project and Detach All.

thanks for your reply!!! Do you mean secect all walls, then detach top/base?  i did that and does not work...

[seutaojiang]

where is the Detach All command/button?

I mean pick a wall and select all similar, then Detach Top/Base=>Detach All.  That's what I do.

....I'll look at your file and report back.

thanks a lot!!  i did what you described but still cannot make it work....

...works here. Detach All allows me to modify and unlock wall layers.

Interesting.  I just did it.  Selected wall "Exterior - 240 110 brick+40 gap+90 stud", right-clicked and picked Select All Instances=>Visible in View, and then clicked Detach Top/Base =Detach All on Contextual Tab. Afterwards, I modified and unlocked wall layer in Edit Assembly section view no problem.

Hi 

In your file, the outer Brick layer is still LOCKED...

Now I did. Thank you for the kind comment. The only thing you missed was to "DETACH AL" on the Options Bar after you click on Detach Top/Bottom.
