I've used slope to roof with relative success with the Speciality/Trapezoid windows, but recently have needed to slope those windows to ceiling. I see that we have the option to do so, but no matter how I build the model, I can't seem to get the window to "see" the ceiling and to slope in any way with "slope to ceiling" checked.
I could find no documentation in the Help section of the program, but thought I might throw a line out here to some of you model building experts out there to help!
Thanks in advance for any hints.
