Domenico: What do you want to achieve in the end? a list of VlaObj or a Selset?
I don't want achieve anything.
I get a selection SS1 using "crossing", ll, ur, ...
If SS1 is a selection setafter exploding or not exploding SS1
if I do the SAME SELECTION with the same method : ssget... crossing, ll, ur...
I have to get in anycase something.SS2 MUST be a selection set and NOT NILSS2 HAS NO RELATION with what :VLA-EXPLODE-SS returns.SS2 is the result of ssget, crossing . . .
But SOMETIMES,
only sometimes, it is NIL.
If, after all, you execute
(setq ss2 (ssget "_"C" . . .))
using the same points
if SS1 was NOT NIL,
you wil get a selection set and NOT NIL ...
. . .
I want achieve to
KNOW, WHY I have to
WAIT, to
obtain that
(setq ss2 (ssget "_C" ll-pt ur-pt))
works correctly after (:VLA-EXPLODE-SS ss1)errore: tipo di argomento errato: lselsetp nilmeans that
SS2 is NILbecause
there is no SSLENGTH for NIL !
