Step 1: Create Model
Create any form you wish to see as a Window Object using ArchiCAD Construction Elements (such as Slabs)
Step 2: Save the Model as Custom Object
Select only the Window parts and show the selection in 2D or 3D. Go to: File/ Libraries and Objects/ Save 3D Model as… The Save Library Part dialog appears. Here you can select the type you want to save (in our example it is a window). Click on Options and make sure that “Editable GDL Script” and “Remove redundant lines from symbol” options are checked (See why ). The custom Library Parts will be saved to the Embedded Library by default, to ensure that they are always available and editable.
In case you need this Library Part in other project, you only need to modify the “Save to…” location and browse for a custom folder.
Step 3: Place the Window
Your custom Window will be automatically loaded to its Tool’s Settings dialog. If you click on the Window Tool and open its Settings dialog you will see your custom Window loaded from the Embedded Library (or from any other location you saved the element).
Now you can place it as a default ArchiCAD Window.
Step 4: Personalize your custom Window
The Window’s Floor Plan view is generated from a special built-in projection which may not match your needs. It can be simply modified, see How to simplify Floor Plan View.
The Wallhole of your custom Window will be always extended with an empty hole to a rectangular object. To create a custom shaped Wallhole, see steps in ArchiTIPS or Custom Shape Door Window on Help Center
