I noticed this discrepancy while editing a pattern
1,6 mm I have tried setting horizontal grid to
50% and to
0,8 mm and the result is the same. If I use ruler tool grid lines are distant
0,8 mm from the middle one. However document crosshair gives a different indication for the center.
While I drag the selection tool, it also show to be at
0,8 mm while above the purple crosshair and not the guide. What one should I listen to?
