3D transform HUD controls
In addition to the onscreen controls, the HUD provides another method of transforming objects
in 3D space, via a set of graphical transform controls.
Choose an axis type.
Drag to move along
X and Y axes.
Drag to move along
Z axis.
Drag to move along
X and Z axes.
Controls in the HUD
•
Move: Three controls in the Move section of the HUD for dragging the selected object in one
or more axes at once. Drag inside one of the square control areas to change the relevant
parameter values of the object in the Canvas.
•
Move Z: Drag here to move the selected object along the Z axis. Dragging to the right
decreases the Z value (moving the object further away), and dragging to the left increases
the Z value (bringing the object closer). Hold down the Command key when dragging to
simultaneously scale the object as it is moved, preserving its size relative to the camera.
•
Move XY: Drag here to move the object 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 dragging a 2D object in the Canvas. Hold down the
Command key when dragging to constrain movement to the initial direction of the drag.
•
Move XZ: Drag here to move the object 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 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 for rotating and scaling the selected
object in the Canvas:
•
Rotate XYZ: Drag in this square control area to rotate the object around 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.
To constrain rotation to the Z axis, hold down the Command key while dragging.
•
Scale: Drag in this square control area 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.
To constrain scaling to the axis corresponding to the initial direction of the drag, hold down
the Command key while dragging.
