Description:
|
Tests whether this
TEDGE has any local or remote self-intersections. This tests uses the edge tolerance, so the checks
tm-check:tedge and then
tm-check:tcoedge and
tm-check:tedge-tcoedge (for each coedge of the edge) should already have been passed. This test then performs in order:
tm-check:tedge-local-self-int,
tm-check:tedge-remote-self-int. A list of any
tm-chk-info error objects that are generated is returned (or an empty list if all is fine).
|
|
|
edge is an argument of type
TEDGE for which the local and remote self-intersections are tested.

|
|
Example:
|
; tm-check:tedge-self-int
|
|
; Check for edge self-intersection.
|
|
(define b (solid:block (position 0 0 0)
|
|
|
(position 10 10 10)))
|
|
;; b
|
|
(define e (car (tolerant:fix (car
|
|
|
(entity:edges b)))))
|
|
;; e
|
|
(tm-check:tedge-self-int e)
|
|
;; ()
|
|
; edge geometry does not self-intersect
