Depending on the story’s overhead, the architect often defines the glass structure inclination by the position of the upper edge of the glass structure in order to then calculate the resulting angle of inclination of the glass structure.
ArchiGlazing works according to the same principle in its default setting: the angle of inclination to be expected from the positions of the baseline and the spot height hotspot is calculated and displayed in the Slanted Glass Structure dialog box.
If you wish to create the slanted glass structure with a particular angle of inclination (1-90°), you can overwrite the value given by ArchiGlazing. The position of the spot height hotspot will then be ignored and the position of the upper edge of the glass structure will be calculated again according to the angle entered.
Note: it is still necessary to select a spot height hotspot when creating glass structures with their own angle of inclination.
