Intention of the site

Now that Graphisoft offers a platform for uploading free objects the necessity for a duplicate here is removed. But the necessity for development of GDL objects is far from gone, and this work is done mostly on top of already heavy daily work loads in most architectural offices.

You need a lot of organization to keep all those cute ideas for helpful GDL tools on track, and you need a way that development can be set aside and resumed when other competing daily demands on your time permit. can help you with this! offers authors the ability to collect their ideas, and maintain "to do" and bugtracking lists on dedicated project pages set up for you within this site. (Similar to the way works for stand alone programs). These project pages can be private to the author or offer various levels of public access.  Upload or embedding of documentation files is possible too.

Setting up a public project page can awake the interest of potential customers who might find you through this site. Clients can also be updated with your progress and any future development plans for your objects.

Please note, this site is NOT intended as merely an advertising page for your objects so far. But you are free to link to your own or other sites, where user can buy your objects.

Beside the object pages there is also a small collection of mathematical resources and a few GDL algorithms dealing with frequently occurring problems.
