can somebody help me?
The vlax-curve may fail if the point data is a very large number so this is unreliable
;start code
(vlax-curve-getDistAtPoint
(vlax-ename->vla-object (setq ax (car (entsel))))
(setq   spoint 
(vlax-curve-getClosestPointTo
(vlax-ename->vla-object ax)
(setq clikpoint (trans (getpoint "\nSpecify point: ") 1 0 ) )
)
)
)
;end code

The return values is "nil"  with points very far from zero.
Somebody have solution?
Scuse me for my bad english
