Hello,
i can't seem to open .ifc files. it gives me the following error "IFC ERROR Refused Command". also, when i open an existing .pln file, it tells me that the IFC 2x2 or IFC 2x3 add-on is missing. so i've tried reinstalling the add-on, it didnt work. i also thought that maybe something else i had downloaded recently might have disabled the add-on. so i did a system restore on my computer to the last day that i had opened an IFC successfully. that didnt work either. so my final attempt was to uninstall ArchiCAD and reinstall, no luck there either. i am still getting that error message when i try to open .ifc files. if anyone has any other ideas, that would be great. Thanks!
Laura
