Change the wall thickness in the online version

[artemisclark]

I am using the online version.
All walls are automatically 3" wide, which is not realistic (wall studs 2x4 = 3.75" + drywall on each side, add 1" = 4.75". Outside walls are 2x6 etc.)
Is there a way to change the wall thickness in the online version?
Thank you!!!!

You can double click on a wall to change its thickness or select more walls and choose Modify walls in the contextual menu.
