Well, I used the "Snap to Grid" and "Snap to Bearing" modes before and, this is what I remember:
When I am in "Snap to Bearing" mode and go in the Snap Parameters, I can only change the number of Bearing Divisions. But when I'm in "Snap to Grid" mode, and go to the same Snap Parameters dialog, I remember having the option to change the Grid Steps, as shown in the picture below.
Well, I don't know if it is a bug, but it is certainly frustrating -> it seems that, even though I am using a Map and a Drawing using a UTM projection (so a with a proper grid, using meters), when I am in "Snap to Grid" mode, the options to change the Grid steps simply aren't there. I have no clue why.
Please see the recording below. Is it a bug? Should the settings be there?
