This definition generates the interior and exterior projection hatches of VisualARQ walls.
You select a wall in the model, and all walls (of the same style or not), will be hatched on their interior and exterior faces.
Some parameters let you choose whether you want to generate the hatches on the interior wall faces, or on the exterior faces, and if it only applies to walls of the same style.
It only works with VisualARQ walls, so it is necessary to install VisualARQ.
This definition doesn't work with curved walls.
