AC 26 5002 crashes when deleting Building material




Probably it's not ok to delete all from "Building Materials" but it shouldn't crash at least, I'm talking about those :



it's crashing only when deleting all folders above and very last entry inside that last folder. it's only me or can anyone reproduce that ? 



Have you loaded any custom library or object....... !!!! Maybe there is a material conflict with something loaded in your library...

no I didn't load any custom libraries, it's very strange to see this because now it's not crashing but pops up with proper error that "the selected attribute couldn't be deleted" 



previously it crashed like 10 times , ok thanks for response ! If I will reproduce that again I will add additional info here.


You must have at least one building material (same for line, fill, pen set, surface, etc.).

So do not delete all, delete all except for one.


You may also want to 'delete and replace'.

So nothing is left in your model (element, favourite, tool setting) that is still using a deleted attribute.
