Please consider adding an option, or automatic Hatch Pattern scales when changing model units.
Very often when converting model units from say feet to inches, the scale of hatches becomes so dense that Rhino would freeze completely or become unresponsive.
Currently we are scripting scaling up each hatch pattern before conversion, but in general or in case this step is forgotten, it would be very useful for all the hatch patterns to scale automatically along with the units.
EDIT: I see this is supposed to work in V6:
but it acts weird. When I convert a sample drawing in Feet with a hatch that has a pattern scale of 5, the conversion to Inches (x12) makes the pattern scale 720, instead of 60. Something is odd here…
