I hope you can help as my boss is busting my **lls.
I am trying to export my Revit file to ArchiCad using the add-in and it come up with the error. I have tried everything I know and asked some other eperienced usre and they have never come across this problem.
It has been succesful before, but then i added more duct, some grille and up comes the error. Have tried to delete the duct and grilles but to no avail.
I hope someone can help other wise I will have to redraw it all.
looks to me like you'd need to contact the author of the Export to ArchiCAD Add-In you're using
