In classification: adding nearest space makes it slow

[Seba]

Hi,

I am trying to create a classification that classifies all the components in a certain area. When I in the classification add the column " Nearest Space", it takes a really long time, and every single action I preform in that classifications after adding the “Nearest Space”(as in adding new rows etc), takes ages. What am I doing wrong? Is there a right way to do it?

-Using Solibri Office 9.12.7
-model size is under 100mb, and the same happens in other models as well.
-No, I can not share the models, unfortunately.
