Description:
|
This extension creates a scheme-object containing an
ACIS geometry
curve class from an
ENTITY class item (e.g., edge).
|
|
|
Geometry classes must be attached to derived
ENTITY class items (e.g., edge) to be displayed and saved. By themselves, curve scheme-objects are useful for evaluating positional, directional, or curvature information without creating a (topology) entity.
|
|
|
edge specifies an edge.
|
|
|
Example:
|
; curve:from-edge
|
|
; Create a linear edge.
|
|
(define edge1
|
|
|
(edge:linear (position 0 0 0)
|
|
|
(position 30 30 30)))
|
|
;; edge1
|
|
; Convert the edge to a curve data structure.
|
|
