3D grid
The 3D grid shows the ground plane of the 3D world. The ground plane is, as the name states, a
plane attached to the ground of the scene, where Y equals 0. The ground plane represents the
dividing line between up and down, that is, between positive Y values and negative Y values. It is
centered on 0, 0, 0.
3D scene icons
3D scene icons are the onscreen representations of cameras, lights, and edge-on lines. An
edge-on line is drawn when an object’s edge faces the camera—which normally results in an
invisible object. Because you can select edge-on lines in the Canvas, you can manipulate objects
that would otherwise be invisible.
Note: No 3D scene icons appear in exported images or movie clips.
