SSGET with "WP"

On area p3 there are 6 line with color 1 to 6.

_$ (setq p3 '((0 0)(10 0)(10 10)(0 10)))

((0 0) (10 0) (10 10) (0 10))

_$ (setq ss (ssget "_WP" p3 '((0 . "LINE")(62 . 5))))

nil

I've tested a ssget with filter "wp",but result is "nil"

 

Are you sure the lines color not bylayer!

 

Hi LUCAS,it is OK,and we set by layer,thanks

_$ (setq p3 '((0 0)(10 0)(10 10)(0 10)))
((0 0) (10 0) (10 10) (0 10))
_$ (setq ss (ssget "_WP" p3 '((0 . "LINE")(62 . 5))))
<Selection set: 2>
_$
_$ (setq e (sslength ss))
1
_$ (setq en (ssname ss 0))
<Entity name: 14755c0>
_$ (setq ent (entget en))
((-1 . <Entity name: 14755c0>) (0 . "LINE") (330 . <Entity name: 14754f8>)
(5 . "78") (100 . "AcDbEntity") (67 . 0) (410 . "Model") (8 . "0") (62 . 5)
(100 . "AcDbLine") (10 1.0 8.0 0.0) (11 6.0 8.0 0.0) (210 0.0 0.0 1.0))
_$ (setq colorname (cdr (assoc 62 ent)))
5

With the "wp" option I think that the whole entity has to be within the window. Maybe try the "cp" option and see if you pick up the objects.

also note, that the WP selection cannot select anything outside the visible viewport. so it's always best to preface your selection line of code with a Zoom Extents, then select, then Zoom Previous.
