Setting Up Grid Controls

By default, the cellview window shows a grid of dots. There are two different grids: the minor (small) grid and the major (large) grid. Minor grid points are white and appear at every micron. Major grid points are green by default and appear at every 5 microns.

The grid defines the points at which the pointer (the small square) snaps to the cellview or to objects. With the snap grid set to 0.5 microns, the pointer can snap to each visible grid point or halfway between each grid point. For example, if your user units are microns and you want to draw objects at 0.5 micron intervals, you set the spacing for the snap grid to 0.5 microns.

To set the grid, you set the X Snap Spacing (distance the pointer can move along the X axis) and the Y Snap Spacing (distance the pointer can move along the Y axis) fields. Setting X Snap Spacing and Y Snap Spacing to 0 produces the same result as turning the environment variable snapToGrid off.

Gravity has precedence over snap grid. While using snap grid, turn Gravity off.

To set the grid type and snap grid spacing:

1. Choose Options – Display.
   The Display Options form appears.
2. Set the visible grid Type to none, dots, or lines.
3. Type the smallest distance you want between the points you enter along the X axis (X Snap Spacing) and Y axis (Y Snap Spacing).
   The value you type is in user units, usually microns.
4. Click OK.
