long time response

Hello, collegues!

my question is how to perform hm for large assemble working?

i have a model which consists more than 4 mln elements and i am upset... every operation i'm waiting for a long time. why does HM work so long? 

i understand if HM saves my large file or checks all model.

but i have masked large part of model and work with less than 10 details which consist average 1000 elements. i was remeshing/connecting each over. and i was waiting every operation 1 minute or 2 sometimes... my computer isn't weak.

any idea?

thanks a lot!
