Transform Centers

---

A transform center (don't confuse it with a pivot point - a center of object transformation and binding) in 3ds max defines a point around which the selected object(s) or sub-objects will be rotated or re-scaled. The transform center is selected via a fly-out on the main toolbar (Fig. 13.4, a). For convenience, you can also assign keyboard shortcuts (Fig. 13.4, b).

• Transform Coordinate Center. In this case, the origin of the current coordinate system is used as the transform center. Depending on the coordinate system, this might be the center of the screen, the coordinate origin, etc. (Fig. 13.5, a).

• Selection Center. In this case, the transform center, in relation to which all transforms will be performed, is the geometric center of the centers of the selected objects (Fig. 13.5, b).

  Note 

  Notice that the geometric centers of the objects are used, not the pivot points - they are two different things!

• Pivot Point Center. In this case, the transform center coincides with the pivot point of the object (Fig 13.5, c).
