Mass Wall intersection

[Anonymous]

Could someone tell me how one could draw walls that are beveled inwards as shown in the image below?

I've been trying but I don't get how I can have the walls joins correctly at the intersections.

I've attached the .rvt file so please take a look if my question is not clear.

Thank you,

Hi, can you provide a plan and section img for the same.

Since your file is on 2019 version, i am not able to open it.

Several approaches: 

...Wall Reveal

...Void Sweep

...Attach to Roof with that pitch and hide Roof.  

...Use the Wall Join Tool to MITER the corners
