Â
Move XY:
Drag here to move the selected object in the Canvas along the X and Y
axes. Dragging right or left increases or decreases the X value. Dragging up or down
increases or decreases the Y value. Using this control is identical to moving a 2D
object directly in the Canvas. Hold down the Command key when dragging to
constrain movement to the axis corresponding to the initial direction of the drag.
Â
Move XZ:
Drag here to move the selected object in the Canvas along the X and Z
axes. Dragging right or left increases or decreases the value of X. Dragging up or
down increases or decreases the value of Z. Hold down the Command key when
dragging to constrain movement to the axis corresponding to the initial direction of
the drag.
Tip:
As in the Inspector, holding down the Shift key while you drag in the HUD makes
larger changes. Holding down the Option key while you drag makes smaller changes.
Rotate and Scale
Two additional drag controls in the HUD let you rotate and scale the selected object in
the Canvas:
Â
Rotate XYZ:
Drag here to rotate the selected object in the Canvas in all axes. Starting
at the origin, dragging up and down rotates the object around the X axis. Dragging
to the left and right rotates the object around the Y axis. Hold down the Command
key while dragging to constrain rotation to the Z axis.
Â
Scale:
Drag here to uniformly scale the selected object in the Canvas. Dragging to
the right or up or both increases the Scale value. Dragging to the left or down or
both decreases the Scale value. Hold down the Command key while dragging to
constrain scaling to the axis corresponding to the initial direction of the drag.
Adjust Around
The Adjust Around pop-up menu, located under the Move, Rotate, and Scale controls in
the HUD, allows you to select which relative coordinate space is used for transforms.
The Adjust Around pop-up menu has three options:
Â
Local Axis:
The default, this option orients the onscreen transform controls to the
objects local axes.
Â
World Axis:
This option orients the onscreen transform controls to the axes of the
3D grid in the Canvas.
Â
View Axis:
This option orients the onscreen transform controls to the
view space
of
the current view. The Z axis is aligned along the views line of sight. For more
information on views, see “Views on page 17.
