How to model this? / curtain wall question?

[jakubc]

Hello
I'm modelling this egg-kind of structure (attached as a picture) and I wonder, if there's any easy way to model this strange windows on it - I mean with details, boundaries and mullions. Can I do that with some window/curtain wall settings, or do I need to just cut it from morphs and stuff and then save in library as a window object?
How would you approach such a project in Archicad?

Thanks for answers in advance, Jakub

It may depend a bit on your particular needs but in general detailed openings with compound curves are best done with morphs as you suggest.
