Geometric Description Language
Encyclopedia : G : GE : GEO : Geometric Description Language
The GDL is the programming language of ArchiCAD library objects and the GSM is the file formats of this CAD objects.
These objects are similar to blocks in the AutoCAD, but unlike the blocks, these are parametric, and the 2D and 3D features are connected, so in all kind of view man can get the corrects visualization (for example a side view on the section, top view on plan, and perspective or isometry in the 3D view).
All versions of the ArchiCAD contains its own default libraries, also objects as furnitures, windows, doors, trees, peoples, cars, construction elements, etc.
There are a several commercial website for saling high-detailed intelligent parametric objects, which are perhaps better and more variable than the default libraries, for example there are a lot of environmental objects like plants, peoples or garden elements, which are not included in the original software.
