Display —
Choose one of the following display
modes:
•
Result—Displays only the result of the Boolean
operations, not the individual operands.
Choosing Result also activates the ProBoolean
level in the modifier stack (page 1–382).
•
Oper ands —Displays the operands that define
the Boolean result. Use this mode to edit the
operands and mo dify the result.
Choosing Operands also activates the Operands
level in the modifier stack (page 1–382).
Also,whenpickingmanyoperands,usethis
mode to avoid having to recalculate the result
each t ime, and then set Display back to Result
at the end.
Apply Material—Choose one of the following
material application modes:
•
Apply Opera nd Ma teri al —New faces created by
the Boolean operation acquire the material of
the operand.
•
Retain Original Material—New faces created by
the B oolean operation retain the material of the
original object.
Sub-object Operations group
These functions operate on operands highlig hted
in the hierarchy view list (see following).
Note: Fortheseoperations,youneednotbeatthe
Operands sub-object level in the modifier stack.
Ex tr a ct Sel ected—Based on the chosen radio
button (Remove, Copy, or Inst; see following),
Extract Selected applies the operation to the
highlig hted operand in the hierarchy view list.
Three modes of extraction are available:
•
Remove—Removes the operand or operands
highlighted in the hierarchy view list fr om
the Boolean result. It essentially undoes the
addition of the highlighted operand(s) to
the B oolean object. Each extracted operand
becomes a top-level object again.
•
Co py—Extracts a copy of the operand or
operands highlighted in the hierarchy view
list. The original operand remains part of the
Boolean result.
•
Inst—Ext r ac ts an instance of the operand or
operands highlighted in the hierarchy view list.
Subsequent modifications to this extracted
operand also modif y the original operand, thus
affecting the B oolean object.
Reorder Ops—Changes the ordering of the
highlighted operand in the hierarchy view list. The
reordered operand is moved to the position listed
in the text field next to the Reorder Ops button.
Change Operation—Changes the type of operation
(see Operation g roup (page 1–385))forthe
highlighted operand. To change the operation
type, highlig ht the operand in the hierarchy view,
thenchoosetheoperationtyperadiooption,and
then click Change Operation.
Hierachy View
The hierarchy view , found at the bottom of the
Parameters rollout, displays a l is t of all of the
Bo olean operations that define t he selected mesh.
Each time yo u perfo rm a new Boolean operation,
the software adds an entry to the list.
You can highlight operands for modification
by clicking them in the hierarchy view list. To
highlight multiple contiguous items in the list,
