I just posted on the ArchiCAD Talk website about this issue. The main problem with this export tool is that it is exporting to the inside face of the wall with windows already removed. I created some properties to be able to export the correct information by using morphs, but again had an issue because I need to export this data in decimal feet and without any symbols (this is an issue when exporting the window height and width). I have no clue how to correct for this in ArchiCAD - do you know how you could adjust a schedule so that it just shows data without symbols?
Anyway, this is my post in ArchiCAD Talk:
These are my schedules from inside ArchiCAD - basically trying to mimic DesignPH.
