Types of 3D Transformations > Scaling

Scaling can be applied by typing scale values into input fields in the Scaling tab of the Transformations command's parameters window or by using manipulators of scaling.

Manipulators of scaling are invoked by the following automenu option:

Activating this option enables display of a bounding box around the selected object in the 3D scene. Ball-shaped manipulators are located on three of the bounding box's vertices. Colors of manipulators coincide with colors of corresponding LCS axes.

To define scaling along one of the axes move the mouse cursor over a desired manipulator. Manipulator will get highlighted and the cursor symbol will change to , or depending on the axis. If you hold the cursor in this position a little longer, a textual tip pops-up. Upon moving cursor over a manipulator there are two ways of operation:

1.Drag and drop
Press and hold , then move the cursor without releasing . Manipulator will follow the cursor along the axis. Final value of the scaling coefficient will be defined upon releasing .

2.Point and click
Click once and release. Manipulator will follow the cursor along the axis. Final value of the scaling coefficient will be defined upon second click .

Linking scale to reference geometry is not available in both modes. You can also input a scaling coefficient value using the keyboard while moving a manipulator.

Keep in mind that scaling is applied along current orientation of object's LCS axes. Edges of bounding box may be non-parallel to LCS axes

Several consequent scalings are automatically summed up.

 

The Scaling tab of the Parameters window contains the Uniform scale checkbox. If this checkbox is enabled (by default), then a single S: input field is displayed. Scaling coefficient value from this field is applied simultaneously along all three axes. Disabling the checkbox replaces aforementioned field by three separate fields X:, Y: and Z: allowing to specify the scaling coefficient individually for each axis.

 

Scaling can be reset to the S:1 value using the following automenu option:

Scaling cannot be suppressed.
