[Lisp] What objects can be selected with ssget

[ziele_o2k]

As in thread title, what objects can be selected with ssget?

Here is site, which I'm using to know something more about entities, but I don't know what kind of entities I can select with ssget...

This maybe help to study ssget and this for processing.

I think that ssget applies to all graphical entities, listed under chapter 6: ENTITIES Section or these that you can "see" in model/paperspace, ofcourse there may be other types of entities than these of the standard AutoCAD, such as AutoCAD Architecture's:

 (0 . AEC_WALL) (0 . AEC_DOOR)

Or Civil 3D.

Thank you.

You could check all the used types in a drawing with:

(setq TypesLst (list))
(if (setq SSX (ssget "_X"))
(repeat (setq i (sslength SSX))
	(and
		(setq typ (cdr (assoc 0 (entget (ssname SSX (setq i (1- i)))))))
		(not (member typ TypesLst))
		(setq TypesLst (cons typ TypesLst))
	)
)	
)
(foreach x (acad_strlsort TypesLst) (print x))

After testing on a drawing made with ACAD Architecture I got:

"3DSOLID" 
"ACAD_TABLE" 
"AEC_2D_SECTION" 
"AEC_BDG_SECTIONLINE" 
"AEC_DOOR" 
"AEC_MASS_ELEM" 
"AEC_MVBLOCK_REF" 
"AEC_RAILING" 
"AEC_ROOF" 
"AEC_ROOFSLAB" 
"AEC_SLAB" 
"AEC_SPACE" 
"AEC_STAIR" 
"AEC_WALL" 
"AEC_WINDOW" 
"AEC_WINDOW_ASSEMBLY" 
"AECS_MEMBER" 
"ARC" 
"CIRCLE" 
"DIMENSION" 
"HATCH" 
"INSERT" 
"LINE" 
"LWPOLYLINE" 
"MTEXT" 
"SPLINE" 
"TEXT"

But I also don't know what are ALL the standard used types so I rely on AutoCAD's object model.

Note that type (assoc 0 ..) is some kind of property that is part of the dxf list, which represents the whole entity/ename, just like (assoc 10, 40, 50 ..).

This is just my vision about this, dunno if I wrote some B.S.
