The Set Grid command
allows you to define a grid pattern that displays on your screen that help
you to enter coordinates with a mouse in an accurate manner. The grid size
is entered by an X dimension and a Y dimension.
The GRID OFFSET (Grid Offset) command allows you to offset the origin
of the grid while retaining its spacing.
Considering the X axis only, imagine a grid spacing of .1, the grid
points would lie on positions .1, .2, .3, .4 etc. With a grid offset of
.025 in the X axis the grid points would lie on positions .125, .225, .325,
.425 etc.
Pro Version 3.5 allows you to display the grid in three new ways : Isometric
front/rear, Isometric left/right and Isometric top/bottom.
