s (and Doors) are able to display the side from which they open in the form of opening symbols, one for the plan view and another for the elevation view (Arch_Window#Openings
). The symbols normally appear in the 3D view. If an Arch_SectionPlane
includes the Window or Door, these opening symbols also appear in the ArchView projection (TechDraw_NewArch
) in the TechDraw_Module
In the 3D view, the opening symbol normally appears at the lower part of the Window or Door. However, in certain cases, the opening symbol appears at the top of the element.
In a window composed of two panes that are supposed to open, one symbol appears at the bottom edge, and the other at the top. This looks ugly to me but I'm not sure if it's the intended behavior. I'd prefer to have all symbols at the bottom edge of the element.
I cannot reproduce this behavior exactly. In my models I've created many Doors; some show the opening symbol at the bottom, and others at the top; this is seemingly random. I suspect it has to do with the original placement of the Arch_Window
object, or maybe it's the orientation of the camera, or the direction of the normal of the object or sketch. I'm not sure, and as I said, I cannot replicate the appearance every single time.
In the attached file the objects Window
, and Door007
, show this behavior. The others have the opening symbols in the "regular" position at the bottom edge.
Of course, in the ArchView (TechDraw_NewArch
) projection of TechDraw everything looks fine because from the top the symbols all look in the same plane. The issue described here concerns only the 3D view of the Windows and Doors.
