How to make the object geometry collection plugin work faster?

[ch_sergey_rb]

I am using Navisworks Manage 2023.
I am writing a plugin for this program using its API to collect the geometry of the elements I need and create an STL file based on this table.
I am using the approach described in this article.
But there is a problem: this approach is very slow. For example, collecting 1000 ModelItems can take about 10 minutes, when it should all be processed in seconds.
Is there any other faster approach than the one described in the article above?
