Changes the size of one or more pickable items in a 3D scene.
How to use
1. Pick the item you want to scale.
2. Click the Scale icon or choose the Tools > Transform > Scale menu command. You can also perform a scale by using the S keyboard shortcut.
3. The views display the center of rotation.
4. Define the origin (center) of the scaling.
By default, scaling is performed according to
the item's local axes. The scaling effect of an item (and especially of
points) often depends on the location of the origin; thus, you may want
to relocate it using one of the following methods:
a) Click the Center hotSpot of the item and drag it to the new
location.
b) Choose one of the predefined Origin options in the Modeling Tool panel.
c) Input the XYZ coordinates in the Center field of the Modeling Tool panel to specify
numerically the location of an arbitrary origin point.
5.
To interactively scale the item, you can use one of the following methods:
a) Click an area of the view that is clear of any item and drag with the
mouse (remember that you must not pick the item as, in this case, a translation
is always applied regardless of the transformation you selected).
b) Define the scale factor by moving the Scale slider of the Modeling Tool panel.
You can constrain scaling along one axis only by enabling one of the following icons in the Application toolbar:
To scale along the X-axis only (shortcut is the X key).
To scale along the Y-axis only (shortcut is the Y key).
To scale along the Z-axis only (shortcut is the Z key).
To constrain scaling of the selected items along XY, XZ, or YZ axes, just select two of the above icons at a time. Leave all the three icons selected if you want uniform scaling on all three axes so that only the size changes while the shape remains the same.
Note. By default, scaling is applied with reference to the origin of the object's local axes, but the Reference Axes section of the Modeling Tool panel allows you to choose among several options.
Options
Scale
To
define the scale factor (default value is 1).
Views. Click an area of the view
that is clear of any item and drag.
Modeling Tool panel. Move the slider
or type the scale factor in the Scale field.
Origin
To
define the scaling center (origin).
Modeling Tool panel. Switch the
chosen radio button on. You have the following options:
Barycenter. The scaling center is
located in correspondence with the barycenter.
Center of bounding box. The scaling
center is located in correspondence with the center of the bounding box
of the item (or items).
Axes origin (default). The rotation
center is located in correspondence with the axes origin.
Point. The rotation center is located
in correspondence with any arbitrary point.
Center
To
define an arbitrary location (defined by the XYZ coordinates) of the origin.
Views. Choose the Edit
mode. Pick the Center hotSpot and drag it to the new location.
Modeling Tool panel. Type the new
values in the XYZ data fields and confirm them by pressing Enter.
Reference axes
To
define the reference coordinate system.
Modeling Tool panel. Switch the
chosen radio button on. You have the following options:
Local (default). Each picked item
is rotated with reference to its local axes.
Parent. Each picked item is rotated
with reference to the coordinate system of its parent node.
World. Items are rotated with reference
to the world (or global) coordinate system.
Object. Items are rotated according
to the axes orientation of a reference object.
Object
To
define the reference object in case you have switched on the Object
option in the Reference
Axes section above.
Views / Modeling Tool panel. Switch
on the Replace check button and pick the reference object
in the scene. Then, drag it in the scene.
