4.21 Rotate cursor

The function for turning the cursor is in the toolbar:

When the function is activated the first time, it is possible to place 2 points and reorient the X axis.

The new alignment of the axes only affects the moving, copying of elements along the X or Y axis. Newly added elements are not aligned (for this, see Rotate datum).
If the axis is to be redefined, activate the function with (M) to redefine the X axis or activate with (R) to redefine the Y axis.
