The grid, also called User Grid or Custom Grid,
is a 2D parametric object with adjustments for
overall size and grid spacing. You can move and
orient user grids anywhere in world space.
You can create any number of gr id objects in your
scene. You name them when you create them and
save them with the scene. You can delete them at
any time.
Like other objects you create in the software,
grid objects are placed on the grid of the current
viewport. By default, this is a plane of t he home
grid, but it can also be another activated grid
object.
Note: Yo u c a n u s e AutoGrid (page 2–7) to create a
temporary or permanent user grid off the surface
of any object.
Using t he Gr id Object
You can use the g rid object as a construction plane
on all three orthographic planes in both directions.
Here ’s how it works:
In the Parameters rollout of each grid object is a
Display group with three options: XY Plane, YZ
Plane, and ZX Plane. These determine which of
the three planes of the grid object is displayed in
the viewport.
When you activate a grid object, the displayed
plane is the construction plane for all viewp orts.
When you c reate a grid viewport, you can choose
from one of six orthographic views (Front, Top,
Left, and so on), or you can choose a special
Display Planes grid viewport. (When you press
the
G key to create a grid viewport, the Display
Planes type becomes the default.) The Display
Planes t ype of grid viewport always displays the
plane chosen by the three option buttons under
Display. Thus, as you switch between XY Plane,
YZ Plane, and ZX Plane, the view through the grid
viewport switches accordingly, and objects created
in that viewport are created on the displayed plane.
When you right-click a viewport label (or go to
the Layout tab of the Viewport Configuration
dialog), you can choose six additional types of grid
viewports, based on the six orthographic views.
