Hi
I'm currently trying to work out how to do something similar from the Glazing used on the Vorosmarty Budapest building (an example of ArchiCAD's). Its the curved sections towards the top that I am trying to achieve however I realise it isn't that all plane sailing!!!
I would be really grateful if anyone could help as it's proving to be quite a headache.
To give an idea I've knocked up something of a visual in sketchup to show what I'm aiming for.
The curves at the top can be done with profiled walls. Use long sections for the glazing and horizontal mullions and very short ones for the vertical (curved) mullions.
