World Space (Biped)

When you use

freeform animation on page 7792 to animate a biped, you can

place a biped limb into the space of another object, or into world space. For

example, if the biped's feet are in world space, then when you move the center

of mass, the feet stay planted in the same location.

World-Space Modifiers (WSM)

World space is the universal coordinate system that applies to the entire scene.

A world-space modifier, as opposed to an

object-space modifier on page 7870 ,

affects an object but uses world coordinates.

A world-space modifier always appears at the top of the modifier stack on

page 1020 . Its effect is independent of its order in the stack.

xref (AutoCAD External Reference)

An AutoCAD external reference. An xref is a variation on a block. A block is

a collection of geometry that is identified by a unique name, is stored in the

AutoCAD symbol table, and essentially behaves as if it is a single object. Xrefs

share block characteristics, and they are similarly defined in the symbol table.

However, unlike blocks, the geometry associated with an xref definition is not

stored in the current AutoCAD drawing; it is stored in another AutoCAD

drawing file. Like a block, there can be many instances of an xref in a AutoCAD

drawing, but only one definition.

Typically, xrefs are used to display the geometry of a common base drawing

in the current AutoCAD drawing without expanding its size. This allows

changes to the reference drawing to be reflected in any host AutoCAD drawings

that refer to it.
