Pull not works

I have created this sketch and wont to pull it to construct a grid - here only with the half of holes. But if I drag the arrow, DS stops, even for hours and I must end DS with the Task Manager. There are too many holes? I read that no limitations in the free version.

My PC is not the newest, it´s with a AMD Ryzen 7 2700 and 32GB RAM and an SSD as system HD. It seems, that processor works only on one core.

Thanks for help.
