ArchiCAD Total Custom Window Tutorial

By David Pacifico, RA, October 30, 2003

Want to create your own total custom windows? From round tops to sloped head or sill, creating your own custom windows in ArchiCAD 8 is easier than ever before. Here's how.

1. Draw or build the custom window with slabs, walls and other tools so that the window is face down on the ground. Be sure to use a single slab for the glass that will also act as the WallHole (so have it go through the Mullions to the jamb.) Build the window so the center of it is the project zero.

2. Select your creation and activate the 3D window.

3. Chose File/GDL Objects/Save 3D Model. Name it and place it in a project specific library. The file type is .gsm (no more .win or .dor).

4. A dialog box will come up with 3 buttons at the top. Select the middle button for a window, check “remove redundant lines” and choose format as “editable gdl script.”

5. Draw a wall and place your new window in it.

6. Now, if your window has a non-square WallHole, you will need to select the window and choose File/GDL Objects/Open Object. (Don’t be afraid! We just need to copy and paste some GDL here.)

7. Click on the 3D Script button.

8. Scroll down until you see the script that is the single slab that you used to make the glass. Select and Copy the script that starts with cPRISM_ "Glass", "Glass", "Glass" and ends with BODY -1. (Note, the data between is the coordinates we will be using for the WallHole).

9. Scroll down to the end of the script and paste. Delete the first pasted line that likely looks like:
cPRISM_ "Glass", "Glass", "Glass"

10. In front of the next line type WALLHOLE. (This cuts the wall for the window.) Click the button Check Script.

11. Save the object and Rebuild.

Extra CreditIf you want to make it a corner window, change the object Subtype by opening the object and clicking on the "select subtype" button in the main window and choosing the corner window subtype.
