"fill not found at the line 440 in the 3D scrip of file casement_a.gsm.
Casement_a.gsm is a macro, a gdl script called by another GDL object, in this case a Window.
The 3D Script is that part of the GDL which tells archiCAD what to generate in the 3D Window.
At line 440 of this 3D Script this macro wants to use a certain Fill Type. However the Fill types is not found in the ArchiCAD Project.
In such as case one could open the macro for editing and check what kind of fill it is calling to find out which fill is missing but that can be hard for someone not familiar with GDL.
What causes the fill missing? If you have a project in which there is a Window that uses a Fill with index number 100. You copy and paste this Window into another Project. But in that Project there is no Fill with an index number 100 so it will not find it and send this error message.
I would recommend selecting the Window in question and going to the Window Seettings Dialog and check whether any of the Fill type of parameters says "MISSING". I would then change that Fill to another existing in your project.
