The 3D ACIS® Modeler (ACIS) is Spatial’s prominent 3D solid modeling engine. 3D InterOp is a CAD data translation framework (Interoperability)

From DocR19

Action

Sets additional validity checking of the body.

Name String

check_ff_tangent_int

Scheme

C++

Description

Enables additional validity checking of an entity from api_check_entity. This relates to intersections between two adjacent faces where:

• Both faces are spline blend surfaces.
• One face is a spline and the other face is tangent to the spline surface.

Intersections are not performed during face/face checking when this option is FALSE. To perform these additional checks, the option must be TRUE.

This option only has an effect when either option lop_ff_int or check_ff_int is TRUE.

Example

; check_ff_tangent_int 
; Create some geometry 
(define b1 (solid:block (position 0 -10 -10) (position 10 10 10))) 
;; b1 
(define e (pick:edge (ray (position 0 0 10) (gvector 1 0 0)))) 
;; e 
(ablell-rad #f 2 4.5 0)) 
;; #entity 3 1 
(blend:network e) 
;; #entity 2 1 
(option:set "check_ff_int" #t) 
;; #f 
(option:set "check_ff_tangent_int" #t) 
;; #f 
(entity:check b1) 
;; checked:

;; 1 shells 
;; 0 wires 
;; 7 faces 
;; 7 loops 
;; 30 coedges 
;; 15 edges
