IFC Position of Archicad Objects

[agroni]

Hi,

I am experiencing a problem with a Library that I have created in Archicad. The position in the IFC Schema seems to be defined by a single point of the element. 

I have created this object in Archicad and saved it as gsm.

The midpoint of the object while saving it as a gsm is on the top of the Zero Point in Archicad.

When exporting this object in IFC, the global position of the object gets defined by the lower left corner of the object. No matter the rotation and position, it is always this lower left corner from the center point of the IFC structure.

Here are the point in Archicad which are defined for the position:

Is there a way to define the another point, respectively, the middle of the cross?

Just for info...I am not good at GDL scripting, so hopefully there is an easy way to do it 🙂

thnx
