Does the planner differentiate between the textures of walls or posts? Or does it simply let you select a 6" or 3" etc. wall section, or a 2-, 3- or 4-way post? I ask because it's nice to have the right quantity of post styles for, for example, Thoumonts exteriors, and sometimes there are particular wall sections you want to make sure you have for parts of a dungeon build. It turns out to be a distraction for my kids to see a wall with a door on it that doesn't really lead anywhere, simply because I ran out of walls... :)

AFAIK you can only use the 3", 6"... yellow walls. There isn't really anything other than the floor tiles with textures and no actual walls or props from the sets are available to use in the planner. Hopefully the next incarnation of the planner will address this.

It uses generic walls. There is hope that a later version of the planner will differentiate wall types, but this requires a 3D element to the program that adds complexity to programing.
