ArchiCAD Objects: GDL Handbook

Objects are good, objects make the model and don't they say "whoever dies with the most objects wins". Not sure about that last one...

But one of the great strengths of ArchiCAD is it's intelligent parametric BIM objects. And although the ArchiCAD library contains a large amount of library objects to cover a wide range of uses you often need to make custom objects for specific design elements of a project. There are essentially 2 ways to do this:

-Graphical GDL

Which essentially means creating an objects in ArchiCAD's modeling tools. And this is not only easy but what most of us do when we need a special window or lighting fixture. You can also create objects in other modeling tools and import as ArchiCAD objects.

-GDL scripting

This is what you do when you need a higher level object with intelligent parameters. It might be something that you need to intelligently change the size of without distortion, materials of different components or select from an array of options.

-Hybrid objects

That's my term for those that start out as being modeled in ArchiCAD or another program and then have parameters added through GDL scripting.

For those looking to create Graphical or Hybrid GDL objects there is a great tutorial on "Building Objects Creation" on the Graphisoft website.

For you hardcore types there is the new GDL Handbook HERE.

$90 get's you over 500 pages of information on creating GDL objects using scripting that you won't find anywhere else. Amaze friends and family with your ability to do GDL gymnastics. Better yet, impress your co-workers and your boss-maybe there is a raise in the works for you this year!

So cruise on down to the CADgarage and get your GDL tuned up now. And buy $10 more of stuff and you get free shipping!
