Description:
|
Removes all
ATTRIB_LOP_EDGE and
ATTRIB_LOP_VERTEX attributes attached to
EDGEs and
VERTEXs on an
ENTITY. These attributes are attached when using the APIs
api_tweak_faces_init,
api_tweak_fix_edge, and
api_tweak_fix_vertex.

|
|
Arguments:
|
|
|
entity identifies the entities on a body which will have their attributes removed.
|
|
|
acis-opts specifies options such as versioning and journaling.

Example:
|
; lop:remove-attributes
|
|
; Make a body
|
|
; Define options in data structure for sweep:law.
|
|
(define opts (sweep:options "cut_end_off" #t))
|
|
;; opts
|
|
; Create an edge from the specified law.
|
|
(define path (edge:law "vec(cos(x),
|
|
|
sin(x),x/5)" 0 20))
|
|
;; path
|
|
; Create an edge that is part of an ellipse.
|
|
(define profile (edge:ellipse (position 1 0 0)
|
|
|
(gvector 0 1 0) (gvector .2 0 0)))
|
|
;; profile
|
|
; Create surface by sweeping.
|
|
(define sweep (sweep:law profile path opts))
|
|
;; sweep
