Unable to Change Material at Wall Connection

[Anna_Gorres]

Hello!

 

I am unable to change the material where two of my walls intersect, shown in the photo enclosed. On the floor plan, it is where the 8' dimension marker is pulling from. Does this have to do with the Wall Connection? I tried looking into it, but so far have not found much. 

 

Thank you in advance,

Probably best to post the plan.

Hello Anna,  Have you discovered this tool yet?  This might be just what you need but again, just a guess.
