Commit working like undo command

bizello

Hi,
I trying to use commit to do some like "undo" command. I´ve found something in the net and one script worked, but others...
The code below works, you can activate only a "commit line" and the face is erased like you want, full control.


def desenha1
modelo = Sketchup.active_model
entities = modelo.active_entities
pt = []
pt[0] = [0,0,0]
pt[1] = [5,0,0]
pt[2] = [5,5,0]
pt[3] = [0,5,0]
abertura = entities.add_face pt
end

def desenha2
modelo = Sketchup.active_model
entities = modelo.active_entities
pt = []
pt[0] = [0,6,0]
pt[1] = [5,6,0]
pt[2] = [5,10,0]
pt[3] = [0,10,0]
abertura = entities.add_face pt
end

def desenha3
modelo = Sketchup.active_model
entities = modelo.active_entities
pt = []
pt[0] = [6,0,0]
pt[1] = [10,0,0]
pt[2] = [10,4,0]
pt[3] = [6,4,0]
abertura = entities.add_face pt
end

#Sketchup.active_model.start_operation("Undo")
desenha1
#Sketchup.active_model.start_operation("Undo")
desenha2
Sketchup.active_model.start_operation("Undo")
desenha3

resposta = UI.messagebox "Erase face?", MB_YESNO

if resposta == 6 then
Sketchup.active_model.commit_operation(a)
else
UI.messagebox "So stay."
end

But I have a part of the another code that doesn't work, I think you don't need all the code, so I'm sending the part with "commit" don't working, the code below:


model = Sketchup.active_model
Sketchup.active_model.start_operation("undo")
entities = model.active_entities
abertura = entities.add_face ptabs
rayt=modelo.raytest(ptabs[0], abertura .normal.reverse)
ptabs_rev=rayt[0]
espess=ptabs[0].distance(ptabs_rev)
abertura.pushpull(-espess)

abeyesno = UI.messagebox "A posição da abertura na parede está correta?
Proceder com o cadastro no Banco de Dados?", MB_YESNO

if abeyesno == 6 then #yes
   cadaberturas(ptabs, espess, cod_arq_atual[0], cod_arq_atual[1], localiza)
  else
   Sketchup.active_model.commit_operation(abertura)
end

I dont' know why the second code doesn't work. I can't see what is wrong.
If you help me, very thanks.

Sérgio.

PS. I need to answer like I solved the my another topis called "edges, angle and rectangle triangle". I'll to write all the problem and describe my solution.

Do not name each operation with the same string "Undo"...

give each a unique name "Draw Face 1", "Draw Face 2", etc.

It's best to wrap each operation in a begin ... rescue ... end block and have an abort_operation call in the rescue clause. (methods are also begin .. rescue .. end blocks, where the def *methodname* takes the place of the begin keyword.)

modelo = Sketchup.active_model
begin
  modelo.start_operation("Draw Wall 1")

  # ... draw entities code ...

  modelo.commit_operation

  msg = "A posição da abertura na parede está correta?\n"
  msg<< "Proceder com o cadastro no Banco de Dados?"
  abeyesno = UI.messagebox( msg, MB_YESNO )

  if abeyesno == 6 then #yes
    cadaberturas(ptabs, espess, cod_arq_atual[0], cod_arq_atual[1], localiza)
  else
    Sketchup.send_action("editUndo;")
  end

rescue
  modelo.abort_operation
  UI.messagebox("Error Adding Enities!")
end

Edit: corrected newline character in messagebox string.

commit_operation and abort_operation do not have arguments:

modelo.method(:commit_operation).arity

0

modelo.method(:abort_operation).arity

0

Hi Dan,

Thank you. Its works now.

I think understand how using commit.
Thanks to show how you do your messages in a script. I liked.
I had some asks about send_action and abort but I saw how they works.
So, I edit this post.
Thank you Dan.

Note that start_operation cannot be nested. Doing a new start_operation after another will commit the first.
