Relocate Gumball

Drag to relocate gumball widget away from its default position.

Reset Gumball

Restores the default placement and orientation for the gumball.

Align to CPlane

Gumball widgets align to the construction plane.

Align to Object

Gumball widgets align to the object direction for:

Exceptions

Free-form top-level objects

The gumball aligns with the construction plane with its origin at the object's centroid.

Curve control points

The gumball z direction (blue arrow) aligns with the curve normal.

The gumball x direction (red arrow) aligns with the curve tangent.

Surface control points

The gumball z direction (blue arrow) aligns with the surface normal.

The gumball x direction (red arrow) aligns with the surface u direction.

Align to World

Gumball widgets align to world xyz directions.

Snappy Dragging

Object snaps are used when dragging.

Smooth Dragging

Object snaps are ignored when dragging.

Drag Strength

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.

Command-line options

On

Turns gumball widgets on for selected objects.

Off

Turns gumball widgets off.

Toggle

Toggles the on/off state of the gumball widgets.

Object actions

Move, rotate, or scale objects

Copy during any operation

  1. Click any gumball arrow, arc, or scale handle.
  2. Start dragging the object.
  3. Tap Alt to toggle copy mode on.
  4. Tap Alt again to turn off copy mode.

Specify a distance, rotation angle, or scale factor

  1. Click any gumball arrow, arc, or scale handle.
  2. In the edit box, type a distance, rotation angle or scale factor that will be applied to the selected object.

Copy with numeric input

Use distance and angle constraint

Normal Rhino distance and angle constraints can be used during a gumball operation.

  1. Start dragging an object.
  2. Type a number, and press Enter.
    This number appears on the command line and is used to constrain a distance or angle of rotation.
  3. Drag the object.
    Distances are constrained along the axis arrow line.
    Angles are constrained in increments of the angle around the rotation arc.

Extrude a curve or surface

  1. Click and drag any gumball arrow on a planar curve or surface.
  2. Press and hold Ctrl.

  3. Release the mouse button.
    The result is an open extrusion. To create a solid, Cap the result.

Note: Press the Shift key to extrude on both sides.

To extrude a specific distance

  1. Start dragging a planar curve or surface.
  2. With the mouse button down, type a distance and press Enter.
    This number appears on the command line and will constrain the distance.
  3. Press and hold Ctrl and release the mouse button.

    The result is an open extrusion. To create a solid, Cap the result.

Gumball widget location and orientation

To move, rotate, or scale the gumball widget controls freely

To move rotate, or scale the gumball widget controls with numeric control

  1. Press and hold Ctrl and click any gumball arrow, arc, or scale control.

  2. In the edit box, type a distance, rotation angle or scale factor that will be applied to the gumball control.

Relocate Gumball

  1. Press Ctrl and click the gumball widget (ignore the text field).

  2. Release Ctrl and start dragging to relocate the gumball widget.

AutoReset Gumball

When an object is rotated, resets Gumball to align with CPlane or World axes based on the initial alignment.

Gumball On

Turns the gumball widget on any time objects are selected.

Gumball Off

Disables auto gumball.

Align to CPlane

Gumball widgets align to the construction plane.

Align to Object

Gumball widgets align to the object direction for:

Exceptions

Free-form top-level objects

The gumball aligns with the construction plane with its origin at the object's centroid.

Curve control points

The gumball z direction (blue arrow) aligns with the curve normal.

The gumball x direction (red arrow) aligns with the curve tangent.

Surface control points

The gumball z direction (blue arrow) aligns with the surface normal.

The gumball x direction (red arrow) aligns with the surface u direction.

Align to World

Gumball widgets align to world xyz directions.

Snappy Dragging

Object snaps are used when dragging.

Smooth Dragging

Object snaps are ignored when dragging.

Rotate View Around Gumball

Rotate both the view camera and view target at the gumball origin when rotating the view.

Drag Strength

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%.

GumballScaleMode

Toolbar Menu

Not on toolbars.

Not on menus.

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

Relative

The scale handle size is the product of the Gumball radius multiplied by the RelativeHandlePositionMultiplier value.

Gumball Radius=x with RelativeHandlePositionMultiplier=1.25
Absolute

The scale handles extend to the object's bounding box boundary.

Note

In the Absolute mode, entering the scale value with different formats scales the object differently.

  • 10 scales the object 10 times.
  • -10 scales the object 10 times and flips the object.
  • 10mm scales the object to 10 mm in the direction.
  • +10mm or -10mm grows or shrinks the object 10 mm in the direction.

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.

Relocate Gumball

The GumballRelocate command moves the gumball origin and orientation of an object.

The other way to move Gumball is to press and hold Ctrl and drag the Gumball widget rather than the object.

Steps

  1. Pick a location for the Gumball origin.
    Press Enter to reset the Gumball y and z axes automatically based on the active viewport construction plane and the x axis direction.
  2. Pick a location for the Gumball x axis direction.
  3. Pick a point to specify the Gumball y axis orientation.
  4. Release Ctrl to use object snaps to place the widget at a snap location.
