How to reset ruler calibration. in coreldraw 2020
Is this what you are looking for: Options > Tools > Zoom/Pan > Calibrate Zoom...
yes i want to reset the default values
I'm not sure there are any default values.Or there probably are, but they may be nothing more than a random number.If you want to adjust your rulers to match true 1:1, open Calibrate Zoom..., hold a plastic ruler under the on-screen horizontal ruler, and adjust the values until the ruler on screen matches your plastic ruler.Do the same thing for the vertical ruler.
