Yes of course - and I don't mean to start the comparison game, that is covered plenty elsewhere! I shouldn't have even said the R word.
I was mainly meaning that we/I am locked into AC for the foreseeable future, so I am very interested in finding solutions that work!
At the risk of veering off topic, I understand the potential in GDL, however, it seems to me to have such a high learning curve to be essentially unusable by the architecture community. It seems/feels like trying to use some sort of advanced robot to hang a picture frame. Sure it is extremely powerful, but all I need is to be able to pick up a hammer and drive in one nail. I don't need powerful, I need easy to use.
I personally would love to spend the time learning GDL, but my employer is not going to pay for that ability. Even if it was a financial option, most architects are not willing/enthused about learning to write code. It is challenging enough getting people to use AC or (gasp!) upgrade to a new software. At least in my limited experience. ...this is a discussion I would love to continue, but perhaps not in my window question!
...back to windows, for now, we are going to find the windows that we can best match our needs, and use 2D drafting where necessary to "fix" them. And probably live with some graphic quirks in some places. We will also be looking into the Cadimage stuff as I mentioned.
Thanks again Laszlo!
