When snap control is turned on, any objects you create, resize or move will jump or ‘snap’ to align themselves with the grid divisions. This is usually the best way of working with Draw, as it is easy to create and align objects manually.
To control the grid, select Grid Setup from the Tools menu and then:
In the Horizontal box, type the number of horizontal grid points you want per unit of measurement.
In the Vertical box, type the number of vertical grid lines you want per unit of measurement.
Use the Always Snap To Grid checkbox to turn snap on and off.
When grid snap is on, it may be useful to view the grid points. Select the Grid button or select Grid from the View menu. Note that Draw may only display every other grid point (or every third or fourth), if the number of grid points per unit of measurement is too high to display on screen without crowding. In this case, movement will still obey the underlying grid settings.
If you've drawn and positioned an object when grid snap is turned off, you can align it to the grid by selecting it, right-clicking and selecting Align to Grid (or use Align to Grid from the Format menu).
