To clear some things up:
As I wrote, the object is not free. Graphisoft UK has all the rights to it. It is distributed by Graphisoft UK among their Archicad subscribers, and made available to other Graphisoft distributors to do the same. If you want it, and have a subscription, contact your distributor. If not, not. I will not post it nor its manual.
This object does some things (check the image, it shows what it can do) that I've had a hard time to achieve with Archicad's standard windows and doors. I mostly do residential work too. For example, I frequently prescribe the Danish Velfac windows, and I've never before been able to mimic their special geometry and modular nature fully. (It's been either 3D or 2D, either elevation or plan, always one pane at a time, never all at once). And of course the object can do a lot more, it's not limited to Velfac. You can define other (your own) presets if you like.
But, this object is not a universal replacement for all standard windows and doors. You will still need (some of) them. So it's not a replacement for Cadimage's Window Builder. And not for the Curtain Wall tool either.
I like it not just because it works well. I also like it because of its simple yet sophisticated user interface. I think some other GDL programmers have things to learn here, since this is done in pure GDL and not with an API that has to be updated for every new Archicad release. It's also "dynamically resizing" which according to Ralph means that despite its capabilities, it will (for small sizes) redraw faster than a similar standard Casement window!
That's all. Check it out for yourself, get an Archicad subscription!
(And please note: I will not answer any more questions about this. Ask your distributor!)
