I went thru the library but can't find an object to suit.
Four Seasons Greenhouses has a special flavor of ArchiCAD with those shapes as object, but they don't seem to be in the real library. Double check before doing this:
You can construct the straight sloped parts using roof elements.
The bent nose piece could be from segmented roof parts using the roof arc tool to get the bend- see attached for tool location.
You'll set the magic wand to a high number to keep the roof segments tiny and the nosing smooth. Once you have the segments for the glass, copy them and simply increase the roof thickness to make the flanking mullions.
For muntins, make short roofs with perpendicular sides.
This exercise relies on cut and paste - use the section view to evaluate and position the pieces as you work.
For the nosing, you could also make a curved wall and save it as a library object, but I suspect you are not performing at that level yet - and for a one-off, why bother?
