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

Align to CPlane

Gumball widgets align to the construction plane xyz directions. The Gumball origin will be at the CPlane oriented bounding box center of the object.

Align to Object

Gumball widgets align to the object.

The default alignment is different for different object types.

Align to World

Gumball widgets align to world xyz directions. The Gumball origin will be at the World oriented bounding box center of the object.

Rotate View Around Gumball

When the Gumball widget is visible, rotate the view around the Gumball origin. Otherwise, rotate the view around the center.

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%.

Common operations

Some operations work the same way on different Gumball handles.

Numeric input

  1. Click on any handle.

  2. Type a number for distance, rotation angle, or scale factor.

Copy object

  1. Drag any handle.

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 length of scale handles is the product of Gumball radius (in pixels) multiplied by the value of RelativeHandlePositionMultiplier. Since the length is based on pixels, zooming the view does not change the handle length on the screen.

Gumball Radius=x with RelativeHandlePositionMultiplier=1.25
Absolute

The length of scale handles is based on model units. The handles extend to the object's bounding box boundary and scale with the object.

Numerical inputs

Click on a scale handle and enter a number to scale the object in one direction.

  • 10 scales the object by 10.

  • -10 scales the object by 10 and flips the object.

    Negative number inputs will flip (mirror) the object.

For the absolute mode only, the number supports units.

  • 10mm scales the object to 10 mm.

  • +10mm or -10mm grows or shrinks the object 10 mm.

To toggle the mode with a macro

  • Use _GumballScaleMode _Mode _Enter

RelativeHandlePositionMultiplier

Only used by the Relative mode. It 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.
