Hi Karl,
Thanks for responding!
I managed to solve that. There were some missing attributes of some objects that I copied from an older file that was worked by someone else.
From my library loading report I saw what attributes were missing and I went to Options>Element Attributes>Attribute Manager and removed the missing attribute from the list so that archciad no longer looked for them.
But moving very slow and my Archicad crashing when i export to BIMx are still very big problems..
I tried turning off half of my layers and succeded (the BIMx file is 176.316 KB) and then I turned off only some layers and suceded (the BIMx file is now 667.364KB), but when I open all the layers that I need it crashes.
a) Is there a way of making my Archicad file "lighter"?
b) Is there a problem with too many customized objects (complicated or not)?
This is my library loading report now. I have many duplicated objects.
c) Is there a way of deleting these not "manually", one by one?
d) Is it possible the crashing could happen because I am running out of disk space? (I am now at 10GB free of 100GB on "C" but sometimes when I export it says only 2.9 gb free or less).
Thank you very much again!
