Syntax:
|
(ds:get-tight-state owner tag)
|
|
|
Arg Types:
|
owner
|
entity
|
|
tag
|
integer
|
|
|
Returns:
|
integer
|
|
|
Description:
|
When the tight state is 1, the load/constraint is tightened, overriding a default shape of 1. There is no effect when the default shape is 0.
|
|
|
The input argument
owner is the face or edge being sculpted. tag is the identifier for the load/constraint to modify. When the tag identifier identifies a load/constraint, the deformable model in the patch hierarchy, which contains the load/constraint, becomes the active deformable model.
|
|
|
This extension returns a 1 or 0, corresponding to the tight state of the tag's tight state.
|
|
|
owner ACIS face or edge on which the deformable model lives.
|
|
|
tag identifier recognizes a constraint.

Example:
|
; ds:get-tight-state
|
|
; Build a test square spline face.
|
|
; (6x6 control points, x and y side length = 36)
|
|
(define dsmodel1 (ds:test-face 6 6 36 36 0))
|
|
;; dsmodel1
|
|
; Clear the face.
|
|
(define erase (entity:erase dsmodel1))
|
|
;; erase
|
|
(define refresh (view:refresh))
|
|
;; refresh
|
|
; Render the loads and constraints.
|
|
(ds:set-draw-state dsmodel1 1
|
|
|
(+ ds-draw-cstrns ds-draw-loads))
|
|
;; ()
|
|
; Make a curve constraint.
|
|
(define crv-cstrn (ds:add-str-cstrn dsmodel1 2 'p
|
|
|
(par-pos .2 .2) (par-pos .8 .8)))
|
|
;; crv-cstrn
|
|
; Turn off tightening.
|
|
(ds:set-tight-state dsmodel1 crv-cstrn 0)
|
|
;; #t
|
|
; Check the tight state - it should be 0.
|
|
(ds:get-tight-state dsmodel1 crv-cstrn)
|
|
;; 0
|
|
; Some operations automatically reset the tight state
|
|
;
|
to 1 - curve tracking, for example.
|
|
(ds:make-tracking-curve dsmodel1 crv-cstrn)
|
|
;; 8
|
|
; We now have a tight state of 1.
