Converting 3dface to a polyline

Issue
How do I convert 3dFaces to polylines ?

Solution
There's no mechanism available to do this directly. What you'll need to do is
collect the 3dFace vertex data, and create a polyline using that information.
Since a 3dFace will probably be construced with differing X,Y, and Z coordinates
you can only re-create them as a 3dPolyline. If the face's Z coordinates are on
the same elevation, you could re-create them as a 2d polyline. Here's some lisp
code to demonstrate this:

还有更简单的？

(defun c:tt ()
(fy:begin)
(if (ssget '((0 . "3dface")))
(progn (mapcar '(lambda (x)
(vlax-put (vlax-invoke
(fy:acspace)
'Add3dPoly
(vlax-get x 'Coordinates)
)
"Closed"
:vlax-true
)
)
(fy:cset->objs)
)
(vl-cmdf ".erase" "P" "")
)
)
(princ)
)

代码还应考虑下ucs和捕捉的问题！
(command "3DPOLY" "non" (trans pt1 0 1) "non" (trans pt2 0 1) "non" (trans pt3 0 1))
