Select last entity

[david_h]

Is anyone aware of a selection ruby that allows one to select the Last Entity Drawn or Placed? similar to the selection option in . .. dare I say it. . .Autocad?

Thx,

David

I wonder if it would be possible in Ruby to get the equivalent of "entlast" in Autolisp ???
I guess no

[david_h]

M. Didier. .. If there is anyone in the universe who could figure this out, it would be you. So, Hopefully. . ..

I was thinking. . .a script that Selects last, or Selects previous would be awesome. I have the Seelction Memorize tool and that works okay mosto f the time, but . .. anyway, think about it.

Thx

Or (ssget "_p"), or tool "select", and Key "P" (in AutoCAD)...
You could do smth Perhaps with the last entity in the active entities selection list ?

def entlast
	model = Sketchup.active_model
	sel = model.active_entities
	ss = model.selection
	n = sel.length - 1
	ss.add(sel[n])
end

I have not tested yet...

He Matt ça marche !!! (Hey it works !)

[Matt666]

[david_h]

okay. . . je suis perdu . . .comment ca marche?

[Didier Bur]

David,
Just wait until me or Matt makes it a usable script.
If you can't wait, open the ruby console and when you need to select last entity drawn or inserted, type "entlast" (no quotes).

David,
Last year RickW(http://www.sketchucation.com/forums/scf/memberlist.php?mode=viewprofile&u=370) wrote Selection Memory 2. Fantastic tool. Definite must have.

%(#0040FF)[yeah . .that's the one I was referring to. Got it. Thanks! ]
Didier and Matt!. . .Merci Mille Fois! I will give this one a test drive.

%(#801000)[Just as a side note, at the 05 basecamp I went to the Ruby Scripting class to hopefully learn somewhat how to do it. Was totally blown out of the room. So I am glad there are you guys around for us dum dums. ]

[david_h]

works great. Thank you!

Here is another one, with context menu. Adds last entity to selection or select last entity only.

entlast.rb

You could also create this as a method for the Entities and Selection classes:

class Sketchup;;Entities
 def last
  return self[-1]
 end
end #class

class Sketchup;;Selection
 def lastent
  add Sketchup.active_model.entities.last
 end
 def lastentonly
  clear
  add Sketchup.active_model.entities.last
 end
end #class

then add your user interface/dialog/menu item, whatever.

This also allows the methods to be called by other scripts in a predictable manner.

Wouah !!
I wanted to do same thing but I but I didn't know how to...
How can you do that : Sketchup.active_model.entlast please ???

[Matt666]

Like that ?

class Sketchup;;Model
	def entlast
		nb = self.active_entities.length
		
		return self.active_entities[nb-1]
	end
end

[RickW]

Or like this:

class Sketchup;;Model

def entlast
  return entities[-1]
end

end #class

Using entities or active_entities depends on whether you want the absolute last entity created, or the last entity created in that space (ie within a group or component).

This is quite useful for selecting the last object extension. Could there be a variation of this that selects and zooms into the last object?
