Hi TIG, thanx again for your suggestions.

What do you exactly mean by initialization?
@unknownuser said:

... so set it to work at initialization...

To me its seems logical to put

@@sf = (Sketchup.read_default 'liquidsscalefactor', 'value', '100').to_s $cmdbooleanhelperscale.tooltip = ("Scalefactor #{@@sf}") $cmdbooleanhelperscale1.tooltip = ("Scalefactor #{@@sf}") $cmdbooleanhelperscale.menu_text = ("Scalefactor #{@@sf}") $cmdbooleanhelperscale1.menu_text = ("Scalefactor #{@@sf}")

in the beginning of the script. Tried that, but it doesn't work. Sketchup gives this error:
undefined method `tooltip=' for nil:NilClass

When I place the tooltip and menu_text lines in the Getinfo class, the tooltip works but the menu-text falls back on the name in $cmdbooleanhelperscale = UI::Command.new("Scale down") {Bhelper::Kleiner.new() } in this case 'Scale down'.

Furter, $cmdbooleanhelperscale1.tooltip = "Scalefactor #{1.0/@@sf} does not work.......??

After some trial and error I eventually found out about how to put a variable in a tooltip.
I already had your suggestion about the tooltip, later I found out how to combine text and variables in
a messagebox. Just combined two pieces of existing information...

About the re-zoom, I tried that. But in the case of rezoom there's no feedback on the scale-action.
You just see the same shape as before. A message-box wouldn't work that good, because you have to
click it away, it interrupts the flow of use.

First post: plugin + toolbar images

HI Ken and TIG,

Thanx for your feedback, I really enjoy learning to code with your help!

I decided to change the approach of Booleanhelper a bit. In the latest version (1.04) its only possible to scale with factor 10, 100, or 1000. You can choose a value from a dropdown-menu.
I've done this because the plugin is only needed to temporary scale up and down a model.
If you work on a scaled up model for instance with scale 100 you can adapt your measurements easily.
In other words, it makes no sense to scale up and down with a factor of eg 9,81.

@TIG Here is the code of version 1.04. I managed to integrate the scalefactor in the tooltip of the toolbar icons, but the method I used for the tooltips is not working for the menu-items, unfortunately.
Further I put this piece of code in the Getinfo class. As a result the tooltips only update after setting the scalefactor. My idea was to put the code for the tooltip outside the classes, but to no avail;

Hi Gaieus,

Thanx, it can be so simple! I checked your website, nice website!

Hi TIG,

Would you be so kind to inspect my code briefly to see if there are things that could be done in a better way or are
actually wrong but function by accident?? (code in first topic)

And a question

The script accepts only input if its a number > 0 It accepts for instance numbers like 1.90.
But it also accepts numbers like 1,90. Nothing happens then when you
try to use it.
How can I filter this kind of input?

I other words, how do I program this:

@@x = 1,90
If x contains  ','
do something

?

Thank you

Hi Ken, you were right! Thanx for the feedback

Solved both problems,

It's only possible to enter a number > 0

You now can choose between scale about origin or scale about object's center.
The default is to scale about the object's center. If you want to change that, open the ruby-file and uncomment
(remove the #) the first line of code. Please reboot ruby to make it work.

Latest version in topic-start

Hello,

I have a question about adding lines of code to my posts. Most of the times it looks like this:

Example Code

all green

But some people on the forum post code in a topic-message with the syntax highlighted.
How does this work?

Tnanks a lot !

@tig said:

Your
sfa = Sketchup.read_default('liquidsscalefactor', 'value', 0).to_f
will work without intermediate steps... although I'd set the fall-back option to '0'.

I got it working like this:

sf = (Sketchup.read_default 'liquidsscalefactor', 'value', '0')[0].to_f

final code in first post. Thnx!

Hi TIG,

@unknownuser said:

I don't see any 'write_default' code ?

My complete code is now attached in the rb-file below....

Am I right? It has to be:

sfa = Sketchup.read_default('liquidsscalefactor','value', 0) sff = sfa[0].to_f

Instead of that I was looking for a more elegant solution like:

sfa = Sketchup.read_default('liquidsscalefactor','value', 0).to_f

but that's not possible?

TIG, Thnx for your help once again, I lost count already

booleanhelperunf1

Hi TIG!

I learned a lot today; and

I got it all working!!!!

Thanx a lot for your help!

I have two final questions though:

(1)
sfa = Sketchup.read_default('liquidsscalefactor','value') sff = sfa[0].to_f . . . trans = Geom::Transformation.scaling(ORIGIN, 1.0/sff)

Is there a more elegant solution to convert sfa to a floating value?

(2)
And I don't understand why sftt is not updating when the scalefactor (sfa) is set??
sfa = Sketchup.read_default('liquidsscalefactor','value') sftt = sfa[0].to_f . . . cmd.menu_text = ("Scale down with factor #{sftt}")

Hi TIG,

implemented the global variable, works great!

I see: the @@variable is only valid within a class right?

Questions

Is results[0] an element of an array? Are all these results of the inputbox stored during the session?

$booleanhelperscalefactor, = results , if I omit the , $booleanhelperscalefactor becomes an array, why?

To give extra info about the scale-factor I adapted the code like this:

cmd = UI::Command.new("Scale factor "+$booleanhelperscalefactor.to_s) {Bhelper::Groter.new() } cmd.small_icon = File.join(imgdir, "bigger.png") cmd.large_icon = File.join(imgdir, "biggerL.png") cmd.tooltip = ("Scale factor "+$booleanhelperscalefactor.to_s) cmd.menu_text = ("Scale factor "+$booleanhelperscalefactor.to_s)

The text sticks to the initial value of $booleanhelperscalefactor, when i change the scalefactor in sketchup the tooltip and menu-tekst won't change.

Thnx for your help.

By the way, I found the Automatic_SketchUp pdf document, a good resource!

Hi TIG, I did some experiments today,

I understand what you mean about the transformation. Using 1.0/nnnn and nnnn is just more convenient..

Setting a global variable was easy. And worked right away. But I also read some wiki that said : "avoid global variables!! ". Is that why you give it ($liquidsscalefactor)such a long name?

Getting a variable from input: also easy.

But to get my variable lsf in to the two classes Kleiner
and Groter, is something I don't understand.
My input method is like this:

` class Getinfo

def initialize() 

	prompts = ["Enter scalefactor   "]
	values = [1000]
	
	results = UI.inputbox prompts, values, "Scalefactor."
	return if not results
	@lsf, = results
	
	UI.messagebox @lsf.class

end

end`

@lsf in Getinfo is a Fixnum class, is that alright?
But in my two classes @lsf is NilClass (empty)

I tried also $lsf and @@lsf.

Any help???

I attached the file I'm working on..

PS:TIG, Realy cool you put all that effort in helping people with ruby and Sketchup! I'm sure lots of people can learn from your posts!

booleanhelper_unf.rb

Thanks guys for the input!

@tig said:

Liquid98
Using
Geom::Transformation.scaling nnnnn
scales everything by nnnnn, probably using its 'bounds.min'
To do the scaling about the ORIGIN - which won't vary and therefore won't move stuff unexpectedly you should use
Geom::Transformation.scaling(ORIGIN, nnnnn)

TIG, thanks for the suggestions, I am fully aware of the fact that
Geom::Transformation.scaling(ORIGIN, nnnnn) will scale
scale everything by nnnnn. With nnnnn as a variable.

But the problem is that i like 1000 while other people prefer 10, and I don't want to
work with a dialog box for user input because than you have to make that choice every time
you use script.
So the best case would be that the user sets the scale factor to what he likes and than the script has to remember the scale factor after sketchup is shut down.

@unknownuser said:

Well I like this plugin because I do scale up and down. However, I think 1000 is a little to much for me, so I set it to 10. 3 10's and you are at 1000. However, I did note that the scaling moves the center of the selection. It would be nice if the scaling kept the selection centered at the same location.

So thanks for the plugin.

Hi ken,

I see what you mean, I have to do some more research on ruby to fix the center problem.
User input for scale-factor: same thing.[/quote]

Thanx for your input

Thanks,
Nice idea!
Some suggestions - add option to scale the whole scene and to zoom extents after each scale.

Hi dedmin,

I tested the script with auto zoom extents after scale, but the problem is that there
is no visual-feedback on the scaling action, you just see the same scaled object.

Well I like this plugin because I do scale up and down. However, I think 1000 is a little to much for me, so I set it to 10. 3 10's and you are at 1000. However, I did note that the scaling moves the center of the selection. It would be nice if the scaling kept the selection centered at the same location.

So thanks for the plugin.

Interesting. How does this differ from using the Scale tool or the Tape Measure tool to resize the model or a component/group?

Well this goes faster, and you don't have to remember the scale factor.
The difference is that you don't have to select a grip point on the scaling-box,
enter a value and press enter. And the other way round..
If you have to that 20 times a day, you'll look for something faster!

This is my modest contribution to the community:

Booleanhelper

The Boooleanhelper plug-in lets you quickly scale up and down your model.
This is especially useful for those people who use Sketchup for 3d printing.
Performing boolean operations or lathe operations on small models (mm size) is problematic in Sketchup, because Sketchup doesn't handle small faces very well.
By scaling up the model these problems disappear. After all operations are done
you can scale down your model to its original dimensions.
Also useful to close small holes in your model.

Your opinions and suggestions are welcome!

Features:

• Visual feedback on scale-factor.
• Scale down at once.
• It is possible to save your work, and scale down later. (feedback not yet provided)
• Auto zoom extents.

Installation:
Open the zipfile and copy booleanhelper.rb and the folder called Booleanhelper into the SU plugins directory.

Have fun!!

Hello,

I'm stupid I know, but what do you guys do to test a script that you've wrote?
My method gets me on my nerves by now. It goes like this:

1 write a ruby script, and save it in the plug-ins folder
2 open sketchup
3 take notice of error message
4 close sketchup
5 modify script
6 goto step 2 until script works.

There must be a more comfortable way to test a ruby script??

please help

Found a solution myself:
