Constrain to Y
Use Constrain to Y to limit the movement and
rotation of objects to the Y axis.
Constrain to Z
Use Constrain to Z to limit the movement and
rotation of objects to the Z axis.
Constrain to XY
Use Constrain to XY to limit the movement and
rotation of objects to the XY plane.
Constrain to ZX
Use Constrain to ZX to limit the movement and
rotation of objects to the ZX plane.
Constrain to YZ
Use Constrain to YZ to limit the movement and
rotation of objects to the YZ plane.
Aim
Use Aim in conjunction with Rotate to
constrain the rotation of the block (or luminaire) to
its local Z axis.
To interactively move an object:
1.
Select an object. For more information, see “Se-
lecting Objects” on page 38.
2.
Click Move .
Note: Once you have selected an object, you can
also right-click and choose Move.
3.
Select the appropriate axis constraint. For exam-
ple, to move the object along the X axis only, click
Constrain to X
.
Note: Once you have selected an object, you can
also right-click and choose Constrain to Axis | X.
4.
In the Graphic window, click and drag the object
to the required position.
Using Drag Increments
You can use drag increments to move (or rotate) an
object incrementally along one (or any two) axes in
the Graphic window.
You can customize the drag increment values for
each axis and toggle them on or off. The drag incre-
ments are in the model units. For more information,
see “Setting Units Properties” on page 46.
To use drag increments:
1.
Click the Edit Drag Increments button or
choose Edit | Transformation and click the Drag In-
crements tab.
The Drag Increments panel of the Transformation
dialog appears.
2. To set the number of incremental units an object
can move along an axis, enter the appropriate value
in the Move X, Y, or Z box.
3.
To set the number of incremental degrees an ob-
ject can rotate along an axis, enter the appropriate
value in the Rotate (Deg) X, Y, or Z box.
