Materials and Linked Architectural Desktop Objects 451

• Component subtype (for example, in sectioned

bodies)

•Layer

• Material assignment

So, for example, if a window object in Autodesk

Architectural Desktop contained a mullion

component, but a portion of the component had a

different material assignment than the rest of it, the

mullion component would appear as two separate

objects when linked into 3ds Max. The objects will

be linked together w ith all the other components

of the window, but you could modify the material

properties of the two mullion objects separately.

If you changed the material assignments in

Architectural D esktop so that the entire mullion

component only had one material assignment,

then when you reloaded the drawing in 3ds Max

there would only be one mullion object present.

Note: Material assignment and Layer are two of the

properties used to separate one component f rom

another. When these are changed in the ADT

drawing, new objects are created in 3ds Max, or

geometry may move from one object to another.

In either case, some scene propert ies are changed,

such as assig ned material or scene layer.
