EDIT: If any Ruby coders are still following this thread, I am having problems that some greebles end up overlapping other faces and then delete faces that are queued to be greebled, then my script stops because it runs across a face that has been deleted. At least that is what I think is happening. So to solve that do I need to test each face to make sure it is not delete before I run the offset and push/pull?

If you are trying to modify deleted objects then you should get an error in the console about that. If that's your problem then do a .valid? test on the entity you try to work with.

I'm currently working on a script where I clean up the model, deleting lots of stuff and I've run into all sorts of problems as things shifts around when you delete entities. It seems the best is to loop over an array copy of entities which you've collected in before hand.

OK, so I'm getting some conflicting reports here (between my home and work computer). I've uploaded the most recent version. It works perfectly on my office XP, SU7 computer. I found a bug that caused SU6 to not work. It should now be working perfectly in 6. But it is not working on my home Vista SU7 machine. So if anyone has troubles with it now, let me know the SU version number and the platform. Thanks!

Thanks Thom, I think that is what the problem is. I am getting this error

Error: #<TypeError: reference to deleted Face>

and it happens when I am repeatedly apply greeble to very messy geometry - like faces that have been greebled many times already and are overlapping all over the place. Eventually it just breaks with that error. I'll add a validity check, and hopefully that will clear it up. I don't think I can keep rechecking the model entities though because the script creates so much geometry that I don't want touched. I only want it to work on the faces that exist before I begin the script. But the more intertwined those faces are, the more likely I am te have one of them overlap and delete a face that has not been greebled, thereby breaking the script. So, I'll try the a.valid and see if that does the trick. Thanks Thom!

Definitely test with face.valid?

if face.valid?
  #do code here
end

As for SU6/7 issues, it could be an issue of the model.start_operation(name,true) breaking SU6, since SU6 only takes one argument. I use this:

(Sketchup.version[0,1].to_i<7) ? (view.model.start_operation "name here") ; (view.model.start_operation "name here", true)

obviously changing "name here" to something a bit more descriptive

Chris Fullmer

Heyhey! My code is similar, and that makes me happy. I'm using

		a = Sketchup.version
		b = a[0,1].to_i
		if b > 6
			model.start_operation("Greeble", true)
		else
			model.start_operation("Greeble")
		end

I like how your code consolidates it all down to just 2 lines though. I already can see all the extra fluff I have in there, so I'll clean it up.

The reason it was not working before is because I accdidentally had written if b >= 6 and clearly I don't want the equal sign. So I've removed it and tested it on 6 on my XP machine and it works great.

I'll implement the valid check after I'm done being busy with work

I just d/l'ed the latest greeble here is a pic, from Vista64 using SU6

Chris Fullmer

I'm not on my Vistaq machine right now, but that is the same error I was getting on it running SU7. But SU6 and 7 both work on my XP machine here at work right now. So it looks like a Vista issue. I'll see if I can find anything in the code that looks a little shaky ( well, it ALL looks a little shaky honestly). I haven't really heard of plugins that work on XP but not Vista.

Chris

Chris Fullmer

Hi Pilou, could you specifiy if that is on XP, Vista, or Mac? Thanks!

If the forum didn't wrap the line, you would see a single line of code. It's called a "ternary expression" since it has three parts (binary is 2 parts, ternary is 3 parts), and it is essentially just a very compact if:then:else statement.

The parts are:
(argument) ? (result_if_true) : (result_if_false)

It's best for short tests, but will work for longer ones, and you can nest them:

def guessme(x=10)
  my_number = rand(x.to_i)+1
  while (guess = ((UI.inputbox(["Guess a number between 1 and #{x} inclusive;"]))[0]).to_i)
    (guess == my_number) ? (UI.messagebox("You're right!");return nil) ; (return nil if UI.messagebox("Too #{(guess>my_number) ? ("high") ; ("low")}. Try again?", MB_YESNO)==7)
  end
end

Chris Fullmer

Yikes, I do not fluently read ternary expressions then. I can see sort of what its doing, but there's a lot in there I don't get. Maybe in time Also Rick, I am getting this error:

Error; #<ArgumentError; Cannot create unit vector from zero length vector>
C;/Program Files/Google/Google SketchUp 7/Plugins/offset.rb;49;in `parallel?'
C;/Program Files/Google/Google SketchUp 7/Plugins/offset.rb;49;in `offset'

C;/Program Files/Google/Google SketchUp 7/Plugins/clf_greeble.rb;200
C;/Program Files/Google/Google SketchUp 7/Plugins/clf_greeble.rb;200;in `call'

I'm sure its because I'm passing bad geometry to your offset script. What do I need to check so as to not pass bad geometry to offset.rb? Thanks!

Seems works fine 6 & 7
Even for the "Tin"
Bravo!

What happens when SketchUp reaches version 10?

Rick will have to learn a new parsing technique!

RickW

Haha! Good point. But Google's backwards-compatibility policy is for 3 versions. By that time, there will be no more need for the "true" flag so it will cease to exist after version 9, and then I'm safe until SketchUp 70.0. At that point, my crystal ball gets a bit fuzzy.

But just in case I'm wrong, this is better:

Sketchup.version.split(".")[0].to_i<7

Can you email me a sample .skp file that's causing the error?

I had the exact same error on one of my files. when I quit SU7. I was asked if I want to fix the error in that file. Which I did. Since then I don't get that error anymore.
FYI: new SU7 install under Vista64, the only installed plugins are what the greeble script requires.

Do you mean that offset.rb is installed with SU7?

Yes, offset.rb is installed with SU7

However my previous post and attached picture still confirms the same greeble problem when used with SU6 operating under Vista64. Mind you there are a significant number of Plugins that maybe contributing to the problem, BTW compospraytool.rb is not installed in that plugins dir.

Chris Fullmer

Bummer, there must be another script that is interefering too then. I'm wondering, do you have makefaces installed on the version 6? If not, could you install it and try it? It also uses progressbar.rb. So it should be broken too.

I might just have to releae a version that does not use progressbar I guess.

Your version is always written 0.25
you don't increase number between version?
