Use Mini Cross 
to place small crosses 
that occupy one quarter of a grid square, and erase quarters of grid squares. Mini crosses are sometimes called 'petit point'. Use single-click to place or erase one at a time, or drag draw continuously. A mini cross is placed in the corner of a grid square nearest to the point where you click.
Note: It may be useful to Zoom In when working with mini crosses.
Up to four mini crosses can be placed in each grid square. It is not possible to place or erase part of a mini cross.
If part of a half height or half width cross is replaced or erased, a mini cross is left in the other part.
It is recommended to use a minimum Cross Size of 1.8mm for the design when using Mini Crosses. Use Design Properties to set the Cross Size used by the design.
