I'm using 2016 Deluxe and whenever I use pick point hatch is seems to take ages for the hatch to draw - even on the simplest rectangle shape.
Any ideas how I could speed this up, or whats causing the slow speed?
I don't know whether or not your version still has the old Pick Point [and?] Hatch tool/command. That's been kind of junky for a few years, but has still been included along with the Pick Point Hatching tool/command.
I would suggest making sure that you are using the Pick Point Hatching tool/command. (others, that have version 2016, will have to verify which-- if not both-- of these tools/commands are in 2016.
