There are times after placing your artwork in the UI, you may want to fine tune its location.
Since we do not, yet, have the ability to enter actual coordinates to place items, we can fine tune our placement using the arrow keys on the keyboard.
But how much does each click actually move your image?
I did a little testing this morning and below are the results I derived.
(note: all values are based on visually inspection in the UI, I have not cut any samples yet to verify the results.
Using the test grid shown above (major lines at 0.1" spacing, minor lines at 0.01" spacing).
Due to image resolution, I used just the 0.1" lines and counted the number of moves to translate the circle 1/2".
Results:
500 X - 1-click = .0065" (77 clicks/0.5")
450 X - 1-click = .0075" (67 clicks/0.5")
350 X - 1-click = .0086" (58 clicks/0.5")
250 X - 1-click = .0104" (48 clicks/0.5")
200 X - 1-click = .0132" (38 clicks/0.5")
150 X - 1-click = .0172" (29 clicks/0.5")
100 X - 1-click = .0263" (19 clicks/0.5")
. 67 X - 1-click = .0526" (9-1/2 clicks/0.5")
