Idea

Hello @sebastian.hemmann,

I do agree with your point 2. Once all walls and pillars are built in a model, I don't want to move them accidentally.

Currently there is no convenient way to make all pillars "No Select". With all pillars highlighed in red I've tried the Toggle No Select button in the Edit Selected Objects panel but it does not work. I guess it's because by default pillars don't have a drawflags node. @Jordan Johnson would it be possible to correct this ?

In the meantime, @sebastian.hemmann you can use this script to make all pillars "No Select":

treenode Walls_surrogate = drawsurrogate(Model.find("Walls"));
int nr_pillars = Walls_surrogate.subnodes.length;
for(int index = 1; index <= nr_pillars; index++){
    Object Pillar = Walls_surrogate.subnodes[index];
    treenode drawflags_node = Pillar.find(">visual").subnodes.assert("drawflags");
    drawflags_node.dataType = DATATYPE_NUMBER;
    switch_noselect(Pillar, true);
}

And you have to hit reset after the 1st time you execute this script.

Later if you want to make all pillars selectable again, you can just switch true to false in the last line.
