• Library Object file extension changes in ArchiCAD 8 and later

A New Feature in ArchiCAD 8 that Library Objects all have the same extension, *.GSM.

The following extensions are no longer available in version ArchiCAD 8 and later, which means you cannot save in these formats (opening such files created with older version is still possible):

All these GDL Library Objects are now saved with the *.gsm extension and they are identified by ArchiCAD by their Subtype.

The handling of GDL files is a bit special case because of the relation of GDL files (*.gdl) and some of ArchiCAD's legacy features.

GDL Script Files are simple text files with the *.gdl extensions. These could be called from any script of any Library Object file and used as macro scripts. However, there is a special use of GDL Script Files: The MASTER_GDL files. ArchiCAD handles any GDL Script File starting with the string "MASTER_GDL...." in their file name in a special way. These files can be used to load attribute definitions, define line types, and materials etc. (see more in the GDL Reference Guide).

How to create GDL Script Files?

There are several ways to do that:

1. Create a simple Text file with a Text Editor Application (like Notepad on Windows, TextEdit on Mac OS X), write in your GDL code and save it. After saving, change the file extension of this simple text file to 'gdl' and that's it.

2. Create an empty Text file. Save it, Change its file extension to 'gdl'. Then use File > GDL Objects > Open Object... In the Dialog, select' GDL Script from the 'Files of type' drop-list so you will see *.gdl files in your folders. Open the GDL files and edit it. After editing, you can save it with the File\Save as... menu item.

It is still possible to save the current Floor Plan as GDL Script in *.gdl format using the File\Save as... menu item. The resulting file will contain only 3D GDL data, so 2D element information will not be saved from the Floor Plan with this type of save.

When a GDL Script files is opened in ArchiCAD 8 or later, the Check Script command is not available. Therefore you may want to copy-paste the content of such a script to the Master Script of an empty Library Object File and check the script there. When doing so, be aware of the default parameters of that Library Object and their default values, so they do not give you incorrect result while checking the script. This can be avoided by specifically setting at the beginning of the script the values of variables used in the script. After checking, these lines can be deleted from the script, if otherwise they are not needed.
