How to select a spline from model space, and get coordinates of two endpoints

How to select a spline from model space, and get coordinates of two endpoints using Autolisp? Thanks a lot

Look into the use of vlax-curve-getStartPoint and vlax-curve-getEndPoint

Insert the code below into your routine:

(setq SplineEntity (ssget "_:S" '((0 . "SPLINE"))))            ;select spline entity (filter out other)
(if (= (sslength SplineEntity) 1)                              ;test if valid user selection
(progn
 (setq SplineEntity (ssname SplineEntity 0)
       SplineEntVLA (vlax-ename->vla-object SplineEntity))    ;convert spline to VLA object

 (setq SplineEnd1st (vlax-curve-getStartPoint SplineEntity)   ;list spline's endpoints
       SplineEnd2nd (vlax-curve-getEndPoint   SplineEntity))
)
)

msasu, just so you know, you don't have to feed vla-objects to the vlax-curve-* functions; it will accept enames.
