Hello guys,
I've been reading some posts about Observers. It seems that some do not work right.
For example SelectionObserver.onSelectionBulkChange, it works in my tests, it identifies when something is selected.
I also realized that he is always working for alerting when I select something. How to disable Selectionobserver?
I tried using the remove, but I think did something wrong. It did not work.

I think it is good to use in my script. It is short showed on next steps:
(1) I select a face with the right mouse button;
(2) Choose the action from the context menu and a dialog box, enter data that identify a set of openings (CJAB);
(3) After another dialog window to enter data that create an opening in the wall;
All this works already.

However, for each opening of a set of openings is necessary to perform all the steps.
I would enter only once with the name of the set of openings. I think do this with SelectionObserver.onSelectionBulkChange.
I would like to do step 1,2 and 3 only for the first opening of the set.
After that I am asked if I want to make another opening for that same set.
If yes, Selectionobserver starts. It keeps the set name to select other face waiting to perform step 3.
And so is that answer until I do not want to make openings for that set. Then disconnect the Selectionobserver.
What do you think? Will that work?
Tell me if I'm on track or whether I should use another observer.
I've tried to do this but For and While, but there is always the need to monitor user actions to trigger the action of the script.
Thank you.

Thanks guys,
I'll try Ruby modules

Hi guys,

I've read some posts about require and rb files.
So, I would like to know if is possible you have a menu that each sub item call a script or function inside differents .rb files? How to do this?
I have a main scritp and inside it there are a lot of function that can become smaller functions in separate files used by mora than one script.
Example: I have two rb files: file1.rb and file2.rb.
File1.rb do an action that use a function from file2.rb . But file2.rb can work alone too. So, I want to create a menu with two subitem to choose file1.rb or file2.rb.
This would be amazing! I could separate my functions and use them in several othes scripts, without copy the code lines.
Thanks

My script must enter an opening in a wall orthogonal or tilted.
The calculations for horizontal and vertical walls are easier, but the script must also include sloped walls at any angle.
The walls of the room must be obtained from an extruded face on the positive Z axis on the xy plane.
You must select the face that will open like you're inside the room and facing the wall.
Click the right button and select the action from the context menu.
A dialog box opens and asks for the parameters of opening: width, height, sill, position (center, left or right) and distance from the corner
in accordance with the position.
Then they get the calculations:
Checks whether element has selected and if it is a face (rule: not possible to make openings in floor or ceiling);
Get the edges connected to that face and separates that are built in Z direction (equal xy coordinates) representing the wall height;
According to the normal of the face, check what is the left edge, base to build on opening;
Creates the vector with p1.vetor_to p2, between the left edge starting point and right edge, adding the Z coordinate value of the sill;
This vector is baseline for the construction of the opening. With point.offset (vector distance) you can calculate the points
to create the face, with distances from the corners
This last action I thought making a very complex way, finding angles and applying Pythagoras, but with some tips and found a little more
studying the API could do more easily.
Thanks to everyone who answered this question.

PS. But I would like to know how the best way to get the edge or face's angle from a axis or plane?

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.

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.

Hi guys,
I have an diagonal edge on XY plane and Z=0. I got its start and end points. I can calculate its length.
I want to use Pitágoras to calculate a triangle rectangle.
I didn´t know to calculate the edge's angle to draw the others sides.
Cay you help me?
Thanks since now.

Hi guys,

Dan, very thanks for the link. The PDF file is excelent. Show how to do, step by step.
I did my first Webdialog works. Very simple, but works.
Thanks to thomthom again (is not first time he help me) by the "Lost Manual".
Course I'll have to learn JS.
Now... back to work...
Thank you a lot.

Hi Dan,
Yes, wx is required and this is write at code's beggining. May be a problem the user needs installing it before.
Other ask, wxFormBuilder shows code in C++, Python and XRC. Is it works in ruby? Sorry this ask, but I'm a designer that wants programming.
Another thing... wx creates very rows of code. Is possible have a .rb file with only the dialog's code? How can I call a function inside a file from other file? For example: I have functions inside a func.rb file, wich they are called and used by the main routine inside a main.rb file. Is it possible?
As honoluludesktop, I would like to see a plugin made with UI::Webdialog. I've tried to use it but I didn't do work.
One example with an elaborated dialog window (radio, pulldow box, text, etc) and how send data to plugin's code, could be very good to learn.
Thanks for help.

Hi guys,
I need to build a interface for a sketchup plugin.
This interface has several data inputs like checkbox, radio, text and dropdown list. Sure, there is a OK button to send data to ruby code for processing. There is a cancel button too.
I downloaded wxFormBuilder wich you can build you form too easy.
The question: is possible using a wxFormBuilder form with ruby and Sketchup API? If yes, how?
Building interfaces have being a problem to me. I can't do this. The dialogs don't close, I don't know how to send data and more and more. May be this is my limit? I don't know.
I needed to do the sketchup to work with Sqlite3. A friend of mine have teached me about data bases. Fine, that's it. It's working.
Someone can teach me about build interfaces for Sketchup plugins.
My work is slow becouse I can't solve this interface problem. This is the big problem, in this time.
Thanks for help.
