first, i'm new user try to be a power. :P and not good at English
i confused that sometimes i deleted object (ALL) in EditMode .
the object is deleted, but not a Pink Dot (object Center).
and hard to delete it
or it is useful for another way?
here is my Detail:
1. Ctrl-x to create New with a Cube selected.
2. tab to EditMode,object still selected shown in Yellow Dots and Lines
3. x to Erase > All
4. object deleted. but not its Pink Dot. and cannot select
5. tab back to ObjectMode, pink dot is Selected , and could Delete now.
But If we turn to select another object say Lamp, then we could not select the pink Dot again. (Right Click,Box selection)
6. after a several try. i found only way to select it back is" Lasso" Ctrl-LMB
have to take times because Lasso Select is not mention in any Basic Chapter of Blender.

that's all to Know Why the Pink Dot did not Erase along with its object.
or it useful for....i don't know
sorry if this is a stupid Question.

ok, here is the solution:

you were in edit mode and deleted all vertices, edges and polys. still, there is the "object". think of it a as container for the actual mesh data. it can be empty, and this is your case. to delete a whole object, tab out of edit mode and press "Del" or "X".

so it also makes a difference. if you add a mesh during edit mode or during object mode. say you have just created a cube, are still in edit mode and add a sphere - you will end up with an object consisting of a cube and a sphere. if you need separate objects, always leave edit mode after you created an object.

hope this was clear :)

thanks for answer but sorry, i think it's not the answer of my asking.

1.I know that object added in Edit mode Would be merge to one object
( means Share the Center Point )
2.Yes,No problem When Delete Object in Object mode, But there was a problem when we hit X > Erase All in Edit Mode
it's about remaining unuseful several Pink Dot(object Center,not vertice)
i don't find any useful of the junk Center Dot .

please Try my presentation in the Above comment. for Cleary my description

you're saying deleting all verticies in an object should delete the object itself?

I know that Delete in Object Mode Will Delete All Vertice.it's right.
But
1 Delete All Select in "edit Mode"
2.will Leave a Pink/white(Center) Dot.
3.tab out to object Mode, Then A to Deselect all.
4. now You could not select it again,
only "Lasso Select" in Object mode could Do this

Just want to know if i leave These many Dot on screen. how this Useful?

it will cleary,or not?

:shock:
