To all in this group. Thanks

 

Clive,

This proved a bit more complicated than I expected. But I think it works.

(defun cerXline ( / vobj p1 p2)
(setq vobj (vlax-ename->vla-object
(car (entsel "Select object: "))))
(setq p2 (getpoint "\nPick point: "))
(setq p1 (vlax-curve-getClosestPointTo vobj p2))
(entmake
(list
'(0 . "XLINE")
'(100 . "AcDbEntity")
'(100 . "AcDbXline")
(cons 10 p1)
(cons 11 (mapcar '- p2 p1))
)
)
(princ)
)

Note, the 11 code of an xline is a vector.
