Change wall textures at once

[nr1]

Hello,

is there a possiblity to change the textures / colors of all walls at once?
(Select the texture / color of the inside / outside seperately?)

When selecting all walls via mouse i always have the problem that the left / right part of each wall is different (so sometimes it's the outside direction, sometimes the inside)

thx

To change the color/texture of the inside wall sides, you should create rooms and modify those rooms, because their modification dialog box allows to set the color of the wall sides touching the room (see More color options for wall section here).
To change the color/texture of the outside wall sides, you should select the walls that are not oriented like the other ones and choose Plan > Reverse walls direction. Then, select walls you want and set the color/texture of the outside.
