CG INFINITY: CHAPTER ONE 11

Controlling the alignment of objects

When you move objects around in CG Infinity, you often want to place
them in particular areas within the frame of the edit window. This is
especially the case when trying to match an object with a background video
or image file, such as a car or a corporate logo. To do this, CG Infinity
provides guides and rulers that help you accurately place and move objects.
Displaying rulers
Rulers provide you with a consistent reference point in the edit window
that identifies the location of objects. To display the rulers, click View:
Rulers. Horizontal and vertical rulers appear along the top and left side of
the edit window. They take their measurement in pixels with the base
reference point (X=0, Y=0) at the top left corner of the frame in the edit
window. You can reset this reference point by dragging the intersecting
ruler lines from the Base Point button at the corner of the rulers to any
position in the edit window. This is especially helpful if you have zoomed in
on an object and want to reset your ruler at a new view.
Note: Double-clicking the Base Point button repositions the base point to the top
left corner of the edit window frame.
Displaying grid and guides
To better position objects, it is a good idea to display the grid as well as use
guidelines within the edit window. The grid is a pattern of points that
appear whenever you click View: Grid. The grid points make it easier to
align objects and position them. You can also change the color of grid
points as well as the distance between each for greater flexibility and
control.
