Display Associated Surfaces
Select an associative surface.
In the Properties palette, under Surface Associativity, in the Show Associativity list, select Yes.
Move the cursor over the surface object.
The surface and all associated surfaces are highlighted.
Turn Off Associativity for a Surface Object
Select an associative surface.
In the Properties palette, under Surface Associativity, in the Maintain Associativity list, select None.
The surface associativity is removed, and new surfaces will not be associated with this surface.
Remove Associativity From a Surface
Select an associative surface.
In the Properties palette, under Surface Associativity, in the Maintain Associativity list, select Remove.
The surface becomes a generic surface. You can no longer change surface properties in the Properties palette and the relationship with other objects is lost.
