Working Pivot Rollout

As an alternative to the object’s own pivot, you can use the working pivot for applying transforms to any object in the scene. This allows you, for example, to rotate an object about an arbitrary, persistent point in the scene without interfering with the object’s own pivot.

You position and orient the working pivot using standard transform tools as well as some special options available on this rollout, and can activate it at any time. You can use it for editing geometry at the object and sub-object levels. Keep in mind, however, that the working pivot cannot be used as a transform center when creating animation (see Animation and the Transform Center).

Note: The scene contains only one working pivot, which is independent of other scene elements such as geometry.

Moving an object along the working pivot Z axis

Attention: Most Working Pivot tools are best used in working contexts other than the Hierarchy panel. For example, you can use it in the Modify panel context while editing mesh sub-objects. For this reason, it’s highly recommended that you use Customize User Interface Main UI group Working Pivot category actions to create a set of controls that you can use anywhere in the 3ds Max interface. For example, you could create a custom Working Pivot toolbar with buttons that give you access to the Working Pivot commands while editing meshes.

Alternatively, you could simply "tear off" the Edit Pivot panel of the Edit menu, which contains a selection of commonly used Working Pivot tools.

Procedure

To use Working Pivot:

  1. Place and orient the working pivot as required:
    • Turn on Edit Working Pivot and use standard transform tools to position the working pivot or use the Place Pivot To commands. Confirm the position directly in the viewport with the caddy or turn off Edit Working Pivot when done.
    • Right-click the viewport and select Place Pivot Surface from the quad menu. Confirm the position directly in the viewport with the caddy or turn off Edit Working Pivot when done.
  2. You can use the currently-set working pivot in either of two ways:

Interface

When any of the modular tools on this rollout is active, a message to that effect appears in each viewport below the viewport name. For example, when you activate Use Working Pivot, the viewport legend reads “USE WP.”

Edit Working Pivot
When on, makes the working pivot visible in the scene and lets you transform it.

When you first enter Edit Working Pivot mode, all transform tools use the Local reference coordinate system by default. You can change the coordinate system while working in this mode, and the tool remembers the reference coordinate system for each transform. Changing the transform, for example from Move to Rotate, recalls the last coordinate system for that transform during the current Edit Working Pivot session.

Exiting Edit Working Pivot restores the last active transform tool. For example, if you’re rotating an object, and you move the working pivot and then exit Edit Working Pivot mode, the Rotate tool will again be active.

Note: While Edit Working Pivot is active, the current selection is locked to the working pivot and cannot be changed without exiting this mode.
Use Working Pivot

When on, lets you transform the current selection (objects or sub-objects) with respect to the working pivot. The transform gizmo, when visible, moves to the working pivot location. In this mode you typically transform the selection by manipulating the gizmo rather than the selection. The reference coordinate system is automatically changed to Working, while the geometric center for rotate and scale transforms is set to Use Transform Coordinate Center.

Click ... to open the Configure Working Pivot dialog and change the display behavior of the caddy.

This mode overrides the current transform space for all transforms. Exiting this mode restores the individual coordinate system for each transform tool.

By default, this sets the geometric center for rotate and scale transforms to Use Transform Coordinate Center; that is, the working pivot position. To specify a different transform center, use the Use Center flyout.

You can activate Edit Working Pivot while using the working pivot; when you exit Edit Working Pivot, Use Working Pivot mode is restored.

Align To View
Reorients the working pivot so that its XY plane is parallel to the active view plane and the X and Y axes are parallel to the viewport edges. Available only in Edit Working Pivot and Use Working Pivot modes.
Reset
Moves the working pivot to the pivot location of the selected object. With multiple selected objects, the working pivot moves to the pivot position of the last-selected object. With a sub-object selection, the working pivot moves to the geometric center of the selection (the averaged position of the selected sub-objects).

If the working pivot doesn’t appear onscreen, use Reset to move it to a known location.

Place Pivot To Group

These controls let you position the working pivot by clicking the mouse instead of with transform tools. To use, click the View or Surface button, and then click in a viewport to position the working pivot there. To exit, right-click the active viewport or click the button again. You’re then returned to the previous transform tool and working pivot mode if you were using one.

View
Places the working pivot in screen space without changing its depth in the screen. Thus the placement is on a grid that is parallel to the screen, intersecting the original position of the pivot.
Surface
Places the working pivot on a surface you click on, or, if no surface is present where you click, the construction plane. This works like AutoGrid, and you can see the gizmo previewing the alignment to the normal of the surface as you move the cursor over it. Clicking places the pivot to the surface and aligns it to the normal (unless Align To View is on; see following).
Align To View
When on, automatically aligns the working pivot to the current view when you place it with View or Surface. This is useful to prepare for transforms in the screen plane. Default=on.

The Edit Pivot panel commands Place W Pivot In View and Place W Pivot On Surface automatically turn off Align To View, and Place W Pivot In View And Align and Place W Pivot On Surface And Align turn it on.

Pin Working Pivot
When enabled, the working pivot does not change when reopening Edit Working Pivot. When disabled, the working pivot is reset upon reopening Edit Working Pivot with a different object selected.
