I am providing you with small file coming from land surveyor.

Performance of Rhino on this file is very laggy.

Please try to do something about this. 600kb model cant be laggy even if there were millions of nested block instances.

Hi Juan - I see that - I do not yet see why - the file is simple enough as it seems. I’ll see if I can figure it out, thanks for the example.
