Room Size fitted to Layout

[Bandit]

Hi All,

First post so be kind.

I have prepared a scheme for OO gauge railway.

That is done.

Where I am at a loss the room is 4.87 x 3.66m

I won't to create the walls surrounding my scheme to see if it fits.

I am looking for a box shape with thick wide lines. But I can not see it in my mind how to achieve this.

Can you help?

You can add a line and set its width to the width of your walls.
