Partly due to the outrage expressed in this thread, I've decided to dis-allow posting of other people's scripts. A script author needs to be able to control which version of the script is available, and where it is posted.

There's a huge difference between someone helping another member out by posting an earlier version that worked for them and someone who's collecting other people's rubies and charging money for them.

Chris said, on this page: yeah I know this version right now has bugs. I made the mistake of updating it thinking I had all the bugs worked out. Then I found some problems and realized I did not have a backup copy of the older version - oops!

Gaieus

Okay John, I guess Jim would like members to follow these guidelines applying common sense of course.

No problems Folks.... I understand.

Oh dear, go to bed and all heck breaks loose

I'll look at the script right now and see if its better. It sure run smoothly on my computer I was testing it on, so it definitely could be the metric problem. Thanks for the patience,

Chris

Chris Fullmer

Well this is driving me nuts. I can see already that the version I uploaded is not the most recent version based on a few tweaks that are wrong. SO I'll go to the computer I was working on this on and see if it has the most recent. I did find a the spot that the script is breaking, and its in a spot that looks stable. Soooo, hopefully I'll find the working copy again and be able to upload that later today.

Chris

EDIT: for now, if someone wants to post an older working version, I wouldn't mind having a copy either But once I get the script working, I wouldn't mind it being removed.

pilou

Take your time!
And a little trick ; when you develop : make some copy any time on any version on any supports!
DD,DVD, Usb,Net etc...
That can seems obvious but now your prog is only maybe less than 10 Kb so some easy to recover
That will be not the case when you will have some megas of code!

Nice addition Chris!

FYI: I just d/led this file. it works with SU 7 but SU6
It might be better to simply post updated scripts in a zip or rar file that way the rar or zip will have a revision number you can always keep track of. Instead of simply changing the original post. Its just an idea I had.

that should have read " FYI: I just d/led this file. it works with SU 7 butnotSU6"

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.

Chris Fullmer

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!

Chris Fullmer

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

chris:
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/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!
