Hello Barry and Lingswigyer,
Thanks for the tips. Your responses are similar to what I found from previous forum posts (mostly from Barry..thx). I am still at a loss. I am sure there is one setting clicked on or off. However, I followed my same procedure, set up a new project from my template and all works fine. In this model the doors and windows only are not displaying at level -1. They display on Level 1 though!
I've checked all settings that I can see or know of and still no luck.
Floor Plan Cut Plane settings same as other projects.
Doors and Windows appear to have same settings within the same storeys of current project and other projects.
I don't see how to set their "home storey" other than setting Sill to Level -1 under sill/header height.
Here are screenshots of what I've done.
I started learning ArchiCAD at age 50....bear with me,
