Drag to relocate gumball widget away from its default position.
Restores the default placement and orientation for the gumball.
When an object is rotated, resets Gumball to align with CPlane or World axes based on the initial alignment.
Turns the gumball widget on any time objects are selected.
Disables auto gumball.
Gumball widgets align to the construction plane xyz directions. The Gumball origin will be at the CPlane oriented bounding box center of the object.
Gumball widgets align to the object.
The default alignment is different for different object types.
Gumball widgets align to world xyz directions. The Gumball origin will be at the World oriented bounding box center of the object.
Object snaps are used when dragging.
Object snaps are ignored when dragging.
Merges the coplanar faces related to the extruding operation when possible.
When the Gumball widget is visible, rotate the view around the Gumball origin. Otherwise, rotate the view around the center.
Sets the amount of the gumball drag as a percentage of mouse movement to control the speed of the gumball movement. The default 100% moves the gumball consistently with the mouse.
To fine-tune placing objects (such as with control point editing) set the strength lower, so large hand/mouse movements result in smaller gumball changes. When the control is closed, drag strength is reset to 100%.
Opens Gumball options.
Angle constraint and Ortho can be enabled.
Drag with Ctrl (⌘) to make a straight loft between the start and end angles.
While dragging, tap Alt (⌥) to create a rotated copy of the object.
Alt (⌥) + click on an arc handle to copy with numeric input.
Click on an arc handle to type the rotation angle.
Double-click on an arc to turn the Gumball widget around the axis.
Move the mouse and click, or type an angle and press Enter.
Drag a scale handle to scale in one dimension along the arrow.
The Gumball origin is the base point of scaling.
Distance constraint can be enabled.
When Object Snap is on, dragging a scale handle near the Gumball origin will snap to it. The object will be made flat in the scaling direction.
Drag with Ctrl (⌘) to extrude inwards or outwards.
Drag with Shift (⇧) to scale the object in three dimensions.
While dragging, tap Alt (⌥) to create a scaled copy of the object.
Tap Alt (⌥) again to leave copy mode.
Alt (⌥) + click on a scale handle to copy with numeric input.
Click on a scale handle to type a scale factor.
Double-clink on a scale handle to change its length.
Move the mouse and click, or type a scale factor and press Enter.
Drag a cut handle to extrude a closed planar curve to cut the intersected object, similar to the BooleanDifference command.
If the cutting curve is an open curve that can cut across the intersected object, both sides of the object will be kept, similar to the BooleanSplit command.
The cut handle only appears on the axis vertical to the curve plane. (Left)
Drag with Ctrl (⌘) to add the extrusion to the intersected object, similar to the BooleanUnion command.
Click on a cut handle to type an extrusion distance.
Common operations
Some operations work the same way on different Gumball handles.
Click on any handle.
Type a number for distance, rotation angle, or scale factor.
Drag any handle.
While dragging, tap Alt (⌥) to toggle copy mode on.
Tap Alt (⌥) again to toggle copy mode off.
Alt (⌥) + click on any handle.
Type a number for distance, rotation angle, or scale factor.
Normal Rhino distance and angle constraints can be used during a gumball operation.
While dragging a handle, type a number, and press Enter.
Continue dragging the handle.
Distances are constrained along the axis arrow line.
Angles are constrained in increments of the angle around the rotation arc.
Ctrl (⌘) + Double-click on a handle.

The GumballScaleMode command sets the size of the scale handles either relative to the gumball radius or based on the object size. This command does not affect the move handles (arrows) and rotate handles (arcs).
| Command-line options | |
|---|---|
|
Mode |
RelativeThe scale handle size is the product of the Gumball radius multiplied by the RelativeHandlePositionMultiplier value. Gumball Radius=x with RelativeHandlePositionMultiplier=1.25
AbsoluteThe scale handles extend to the object's bounding box boundary. NoteIn the Absolute mode, entering the scale value with different formats scales the object differently.
|
|
RelativeHandlePositionMultiplier |
Specifies the size of the scale handles relative to the Gumball radius setting. Numbers larger than 1 make the gumball scale handles longer than the Gumball radius. Numbers between 0 and 1 make the gumball scale handles shorter than the Gumball radius. |
