ssget "_P" and then continue to select more with filter or remove from selection

[paullimapa]

Is there a way to do ssget "_P" and then continue to allow the option to select more adding to selection total set or remove objects from previous selection set with filter list?

Try to search, it was here a few times before.

Just what pops out of my mind...

(initcommandversion) (command-s "_.select" "_p")

[paullimapa]

Thanks for your quick reply. I'm aware of the Select command. What I'm trying to do is include in the ssget function the previous selection set with filters and continue to either select more or/and remove objects ie: (setq ss1 (ssget "P" ' ( (0 . "LINE")))).  This unfortunately, just creates a selection set filtering out LINE objects from the previous set but does not allow me to continue to select more LINE objects or deselect (remove) objects from the now highlited "P" set.

Just to clarify, my suggestion does allow you to add/remove objects from the highlighted previous selection.

It does not allow to apply a filter on them.

[paullimapa]

Yes, filtering is what's missing from your answer. Thanks again.

Something like this, perhaps

(vla-sendcommand (vla-get-activedocument (vlax-get-acad-object)) "_P\r")
(setq ss1 (ssget '((0 . "Line"))))

Hope this helps,
Henrique

Hi Gabriel,

it sends the _P to the command line, the \r is a carriage return (enter)...

Nice trick Henrique!

I probably never realized that classic hidden selection options are still available under (ssget). 

Command: (ssget)
Select objects: ?
*Invalid selection*
Expects a point or Window/Last/Crossing/BOX/ALL/Fence/WPolygon/CPolygon/Group/Add/Remove/Multiple/Previous/Undo/AUto/SIngle

 This the the P that (vla-sendcommand (vla-get-activedocument (vlax-get-acad-object)) "_P\r") selects!
