Scale

It moves selected vertices, lines and faces to scale.

Scale

Handle

It shows three arrows along with X/Y/Z axes, and you can scale vertices, lines and faces to X/Y/Z axis direction with mousedragging of the left button.

You can scale proportionally by mousedragging the yellow center.

When you mouseclick the top of the arrow (red, green, blue or yellow parts), you can input a scaling factor.

When you mousedrag the handle with Ctrl and Shift key, you can change the direction of the handle.

And you can input a number of a rotation angle for a handle by mouseclicking the red, green, blue or cyan ring.

You can move the center of the handle by mousedragging with Ctrl key. And when you click the mouseright button while dragging, the center is snapped to the nearest vertex.

Move the center of the handle
by dragging with Ctrl key.		   Snapped to the nearest vertex
by clicking a right button while dragging.
Cage

A box is displayed in the cage mode. A face of a cage changes yellow when the mouse cursor is on the point in the face, and the object is scaled when you mousedrag the face of the cage.

Original   The face of the cage changes yellow when the mouse cursor is over it   Scaled by dragging

You can input a number of a scaling factor by mouseclicking a center point on a face of a cage.

Default
It scales in the same ratio for every one of X, Y and Z axes.
Screen
It scales in the ratio in the length and breadth of externals on the screen. It is necessary to note that the actual shape is sheared on the perspective view.
Property
You can input a scaling factor and a center of the position in the property.
Rate
It specifies a scaling factor by a rate.
Size
It specifies a scaling factor by size for a selected part.
Initialize
It restores scaling factors to 1.
Center
It specifies a base position for scaling on X, Y and Z axes.
Zero
It restores a base position to 0.
Local
It restores a base position to a center of a local coordinate of a current object.
Gravity
It restores a base position to gravity of selected vertices, lines and faces.
Selected
It restores a base position to a center of selected vertices, lines and faces.
