||Enter a value for the
Grid Step field; for example, 100 mm.
The grid step is the increment
used for snapping (to grid). Imagine a grid placed over your workspace,
consisting of squares. The value you enter in this field becomes the
distance between the lines of each square.
If you enter 100 mm, then, when
routing, the run will extend by 100 mm at a time. Runs begin, end and
turn at grid intersections (there are ways of overriding this). Similarly,
when placing parts in free space (as opposed to on a run), they will place
at grid intersections.
The grid step setting will display in the General Environment toolbar at
the bottom of the 3-D viewer. You can change it in the toolbar during your
session but the new value will only apply to your current session. If
you close the application and reopen it, the toolbar will again display the
value in the General tab page.
