Move Vertical. Press Shift to constrain the
movement to a single axis.
Rotate—Lets you select and rotate sub-objects.
Scale—Lets you select and scale sub-objects.
Flyout options are Scale, Scale Horizontal, and
Scale Vertical.
Pressing
Shif t as you scale constrains the
transform to a sing le axis.
Fr ee form Mode—Lets you select and move,
rotate,orscalevertices,dependingonwhereyou
drag. Afteryoumakeaselection,theFreeform
gizmo appears as a rectangular b ounding b ox
around the selected vertices. As you move the
cursor over the gizmo’s various elements and
inside the gizmo, the cursor’s appearance, and the
result of star ting to drag in this location, change:
•
Move—Position the cursor anywhere
inside the gizmo and then drag to move the
selection. To constrain movement to the
vertical or horizontal axis, depending on how
you begin dragging, press and hold
Shif t
before dragging.
•
Rotate—Positionthecursoroveragizmo
edge center point, and then drag to rotate the
selection about the pivot. As you drag, the
amount of rotation is shown in the center of the
gizmo.
Ctrl +drag to rotate in five-degree increments;
Alt +dragtorotateinone-degreeincrements.
Freeform rotation respects the angle snap (page
2–37) status.
•
Scale—Positionthecursoroveragizmo
corner and then drag to scale the selection. By
defa ult, scaling is non-uniform; if you press
and hold
Ct rl before dragging, scaling is
uniform on the horizontal and vertical axes.
Press and hold
Shi f t before dragging to
constrain scaling to the vertical or horizontal
axis, depending on how you begin dragging.
By default, sca ling takes place about the gizmo
center. If you’ve moved the pivot (see following
item), you can sca le about the tr ansform center
instead by pressing and holding
Alt before
dragging.
•
Move pivot—Position the cursor over the
pivot, a wireframe cross that appears by default
at the center of the gizmo. When this cursor
appears, drag to move the pivot. Rotation
always occurs about the pivot; scaling t akes

before dragging.
Tip: By default, the pivot always resets to the
center of the gizmo when you make a new
selection. If you prefer to retain the offset f rom
selection to selection, you can toggle this feature
w ith the Reset Pivot On Select ion command.
This command is not available in the editor
interfacebydefault;youmustusetheCustomize
User Interface dialog (page 3–792) to add it.
If you
Ct rl +select one or more vertices outside
the gizmo, the gizmo expands to encomp ass the
entire selection.
Mirror—Mirrors selected vertices and flips
UVs. Flyout options are Mirror Vertical, Mirror
Horizontal, Flip Horizontal, and Flip Vertical.
Flip first detaches the selection along its boundary
edges and then applies a Mir ror Horizontal or
Vertical depending on the mode.
Turn on Target Weld, and then dr ag one vertex
to another vertex, or one edge to another edge.
As you drag, the cursor changes in appearance to
cross hairs when it’s over a valid sub-object. While
this command is active, you can continue welding
sub-objects, and change the sub-object level. To
