need to move the base slightly upwards in the Y direction so it
is positioned on the X, Z plane. To do this you use the Move transformation
tool located in the Toolbox.
The upper half of the Toolbox contains
the tools for transforming objects (selection, move, rotate, scale)
within Maya. When you move your mouse cursor over any transformation
tool icon you see the name of the tool appear next to the mouse
The tool’s name also
appears in the Help Line at the bottom of
the Maya window. The Help Line has an additional
purpose: it displays summary instructions as you use tools that
require several steps.
Selection and de-selection
you can transform an object, you must ensure it is selected. You
can select objects by clicking them directly, or by dragging a rectangular
bounding box around some portion of the object to indicate what
you want selected. To deselect an object, you simply click somewhere
off of the selected object.
To select the base primitive object in
the scene view
- Do one of the following:
use the Move Tool to adjust the position
of the base
- Select the Move Tool from
A move manipulator icon
appears over the primitive cylinder in the scene view.
Tool Manipulator has handles that point in the direction
of the three fundamental axis directions of 3D space: X, Y, Z. The
handles are colored red, green, and blue based on their function
related to the X, Y, Z axes and control the direction of the movement
along an axis.
When you click a specific
handle, it indicates that the move is constrained to that particular
- In the side view, drag the green Y manipulator
handle to move the primitive cylinder upwards in the Y direction.
Move it upwards enough so that the bottom of the base cylinder is
aligned with the X axis (the thick dark line of the grid)
The base cylinder now
needs to be rotated slightly so the front of the base is parallel
to a grid line. Since each facet of the octagon represents 45 degrees of
a circle, you need to rotate the object approximately half of that
amount or 22.5 degrees.
To use the Rotate Tool to
adjust the position of the base
- Display all four views by positioning
the mouse cursor in the view and tapping the spacebar of your keyboard.
The four view panel appears.
- Position the mouse cursor in the top
view and tap the spacebar once.
The top view appears
in the workspace.
- With the base cylinder selected, choose
the Rotate tool from the Toolbox.
A rotate manipulator
icon appears over the primitive cylinder in the scene view.
Tool manipulator consists of three rings (handles), plus
a virtual sphere enclosed by the rings. The colors of the handles
correspond to the X, Y, and Z axes. The handles are colored red,
green, and blue based on their function related to the X, Y, Z axes
and control the direction of the rotation around an axis.
- In the top view, drag the green Y manipulator
ring to rotate the primitive cylinder so that one of the facets
of the base cylinder is aligned with the grid as shown in the image
You are rotating the
cylinder around its Y axis.
You may be asking yourself
the question “How do I know if I’ve rotated the base exactly 22.5
degrees?” You can check the accuracy of the rotation by viewing
the Channel Box. Rotate
Y should be close to 22.5 degrees.
You can undo and
redo the last action you performed. Undo reverses the last action
you performed on a selected object. It also reverses any action
you performed from the Edit Menu
an action select,
Edit > Undo, Redo, Repeat.
Maya allows you to perform multiple undos.
