[Plugin] Boolean helper update 08122011

TIG

Jim's 'joke' refers to the fact that a lot of SketchUp tools have similar sounding names and you do 'ScaleUp' things using your tool - I suspect that it's 'lost in translation' ?

Another couple of things...

view.zoom_extents
must be
Sketchup.active_model.active_view.zoom_extents
as you haven't defined 'view' otherwise.
An alternative is
Sketchup.send_action("viewZoomExtents:")

a = Sketchup.read_default('liquidsscalefactor','value')
would be better to trap older wrong class-type values [your earlier version probably saved the value as the wrong 'type' - it should be saved as a 'String'] - like...
a = Sketchup.read_default('liquidsscalefactor','value'**,'100'**) if a.class==String a=a.to_f else ### might be an Array or something else! a=100.0 end#if
The basic Array class doesn't have '.to_f' as a method... although some scripts might extend that class methods and add it... and then there might not be an error like that, BUT best fixed in your code...

Oops!

Following error code on my machine.

Error Loading File booleanhelper1.05.rb
undefined method `to_f' for [10]:Array

Notice, I have been following this thread not so much as I need the plugin, just trying to keep up with the programing.

Hi Ken,

Thanx for the feedback, Boolean helper writes the scalefactor to the registry. I think an old value from previous version sits there. To fix it

Copy this code:

Sketchup.write_default('liquidsscalefactor','value',100)

And paste it in your ruby-console, press Enter and restart SU, and let me know if it worked...

TIG

Please write/read your values as a String - '100' etc.
It's safest to be consistent.
I know and integer like 100 would be OK and make a float 100.0 but so would '100'...
As explained an Array like you tried initially [100] is likely to break it !

@ Jim, no i did not get your joke .... Lost in translation I suppose

I've set everything to string now:

Is it correct like this??

TIG

if Sketchup.read_default('liquidsscalefactor','value', '100') == nil Sketchup.write_default('liquidsscalefactor','value',sf) end
Will never ==nil as you tell it to set it to '100' if it is nil in the 'read_default' [the third optional argument].
It's better to use something like my example... where you read its value, and it's set as '100' it it's NOT already set at all, OR it's set to be whatever it's value is already when read; then IF it's not s string it's set to '100' - to rescue us from you having accidentally setting it to something like an Array [100] etc in an earlier version...
Just read through your code and every time you read/write/get/set sf/@@sf etc check it's a string - except when you use it in a calculation - for the Scaling etc - where you use .to_f on it to turn it from a string into a float value - as the scale wants a 'number' - the registry entry and inputbox dialog use a 'string'...

if Sketchup.read_default('liquidsscalefactor','value', '100') == nil

Little mistake, replaced all the read_default lines in the same way.. (in the editor)

hi,

I've been following this topic due to a keen interest in 3d printing, and have wanted to make a suggestion.

I can't find the code I played around with in the past which is the basis of my suggestion,
however Jim mentioned where it comes from in another post today, so I'll simply pass that on...http://code.google.com/apis/sketchup/docs/ourdoc/model.html#add_note

the idea is just write a screen note when working at scale and remove it when back to output scale.

I was looking into actually blocking exporting at scale, but didn't get it working.

I haven't had time yet, but I'll do some Mac tests and let you know if there are any issues.

Hi John,

I like your idea's! I know from experience that exporting a model in the wrong scale is a common mistake in 3D printing design... Not a lethal mistake, unless you order the model in the wrong size... Maybe there's something like a Read-only or immune method in Ruby, I will look for that...

Also the idea of model-notes is a good idea. I suggest an 'X' sign for every scale-up action. So when the model is in normal state no X sign is visible. If you've triple-scaled your model there will be three X's in the left top of the screen.
Also the X model-note provides a good feedback on the scale action, so after the scale action the script can do viewZoomExtents without loosing your sense of scale.
I'm also curious how this script behaves on the mac, so let me know..

hi,

had a short play last night, everything seems to work as designed... however, an interesting but 'odd' feature was the ability to independently scale anything selected.
I had assumed it would only work on a 'scale all' basis and was checking a not-grouped object when I had only a single line selected.

to my surprise it scaled the line and I played around modifying solids for far too long.

I think this ability should be a separate feature or even a second tool.

It could cause huge confusion when preparing models for printing, but is great fun for creating objects.

I would suggest limiting Boolean Helper to 'auto select-all' and scale up/down at the pre-set's.

and then a second plugin 'edge scaler' with a incremental slider at the tool-tip would be great.

just my thoughts

Hi John,

I see! when scaling up and down a separate line or face you get all kind of weird shapes... really fast

Edge scaler is a great idea! Maybe that will be my next project... thanx for the suggestion.

So the plugin has to select all before scaling. Thats better indeed, I'll fix that.

What do you think about the X message-scale-feedback?

Nice to hear it functions on Mac, too

liquid,

the "X" factor is good... (but not the TV show)

You don't need to 'select-all' in the code, just use model.entities.to_a as the collection of things to transform in the scale up/down - that way everything gets caught in the scaling up/down changes.

A screen-note wouldbe useful to remind you that you have scaled... then the code can erase it when you've scaled down...

I like where this is going!

@ TIG

yeah, "select all" is user language.

model.entities.to_a = programmers language

Working on the feedback of the scale action (X = one time scaled up XX =two times etc.)
I have some variable (array) filled with X characters. Its called $xfeedback

To put it on screen I use:

@xnote = model.add_note $xfeedback.to_s, 0.01, 0.02.

That works. But to update it I would like to delete the screen-note entity before showing it again like this:

model = Sketchup.active_model entities = model.active_entities entities.erase_entities(@xnote) if @xnote

I know to delete something with erase_entities it has to be an array. So I tried also this:
entities.erase_entities(@xnote.to_a) if @xnote

but it's not working.

Code structure is like this:

<span class="syntaxdefault"><br />require </span><span class="syntaxstring">'sketchup.rb'<br /><br /></span><span class="syntaxdefault">$xfeedback </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> </span><span class="syntaxkeyword">[</span><span class="syntaxstring">"X"</span><span class="syntaxkeyword">,</span><span class="syntaxstring">"X"</span><span class="syntaxkeyword">,</span><span class="syntaxstring">"X"</span><span class="syntaxkeyword">,</span><span class="syntaxstring">"X"</span><span class="syntaxkeyword">]</span><span class="syntaxdefault">  </span><span class="syntaxcomment"># Test situation presuming 4 times scaled up.<br /><br /></span><span class="syntaxdefault">module Test<br /><br />class Scaledown<br />    <br /><br />def initialize</span><span class="syntaxkeyword">()</span><span class="syntaxdefault"> <br />         </span><span class="syntaxcomment"># Scaling action<br /></span><span class="syntaxdefault">         <br />     model </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> Sketchup</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">active_model<br />     entities </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> model</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">entities<br />     if entities</span><span class="syntaxkeyword">[</span><span class="syntaxdefault">0</span><span class="syntaxkeyword">]</span><span class="syntaxdefault"> </span><span class="syntaxkeyword">!=</span><span class="syntaxdefault"> nil<br />    <br />    l </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> $xfeedback</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">length</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">to_i </span><span class="syntaxkeyword">-</span><span class="syntaxdefault"> 1  <br />    $xfeedback</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">delete_at</span><span class="syntaxkeyword">(</span><span class="syntaxdefault">l</span><span class="syntaxkeyword">)<br /></span><span class="syntaxdefault">    <br />     model </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> Sketchup</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">active_model<br />    entities </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> model</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">active_entities<br />    entities</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">erase_entities</span><span class="syntaxkeyword">(@</span><span class="syntaxdefault">xnote</span><span class="syntaxkeyword">)</span><span class="syntaxdefault"> if </span><span class="syntaxkeyword">@</span><span class="syntaxdefault">xnote<br /><br />    </span><span class="syntaxkeyword">@</span><span class="syntaxdefault">xnote </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> model</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">add_note $xfeedback</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">to_s</span><span class="syntaxkeyword">,</span><span class="syntaxdefault"> 0.01</span><span class="syntaxkeyword">,</span><span class="syntaxdefault"> 0.02<br /><br /><br /><br />    else <br />    nil<br />    end</span><span class="syntaxcomment">#if<br /><br /><br /><br /><br /><br /><br /></span><span class="syntaxdefault">end</span><span class="syntaxcomment">#def<br /></span><span class="syntaxdefault">end</span><span class="syntaxcomment">#class<br /></span><span class="syntaxdefault">end</span><span class="syntaxcomment">#module             &nbsp;</span><span class="syntaxdefault"></span>

Shouldn't it be @@xnote ?
Anyway, something like...
entities.erase_entities(@xnote)
should work... or use [@xnote] to make it an array, if it MUST be one (?)...
However, this will work too
@xnote.text='newtext'
to change it ???

driven

may not be of any help, but

when you create a screen note SU creates a new Text entity (each time)

"#Sketchup::Text:0x1ef0a000", "#Sketchup::Text:0x1f0131a4", etc...

so I guess if you capture those you can delete them.

Hello friends,

I made some improvements to the boolean-helper plugin:

it scales everything in the model
it gives feedback on the total scale-factor
it auto zooms to the model-extents.

But I need some help:

When the model is scaled up, feedback is generated in the form of a sketchup::text
entity. My problem: when the the model is deleted (not select all), the text entity remains on the screen ( entities[0]) while there is no model.

So I have to monitor that.

How do I do that??

I came up with this solution:

<span class="syntaxdefault">if  entities</span><span class="syntaxkeyword">[</span><span class="syntaxdefault">0</span><span class="syntaxkeyword">].</span><span class="syntaxdefault">class </span><span class="syntaxkeyword">==</span><span class="syntaxdefault"> Sketchup</span><span class="syntaxkeyword">;;</span><span class="syntaxdefault">Text </span><span class="syntaxkeyword">&&</span><span class="syntaxdefault"> entities</span><span class="syntaxkeyword">[</span><span class="syntaxdefault">1</span><span class="syntaxkeyword">]</span><span class="syntaxdefault"> </span><span class="syntaxkeyword">==</span><span class="syntaxdefault"> nil<br />         </span><span class="syntaxkeyword">@@</span><span class="syntaxdefault">xnote </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> entities</span><span class="syntaxkeyword">[</span><span class="syntaxdefault">0</span><span class="syntaxkeyword">]<br /></span><span class="syntaxdefault">         </span><span class="syntaxkeyword">@@</span><span class="syntaxdefault">notetext </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> </span><span class="syntaxstring">"   "<br /></span><span class="syntaxdefault">         </span><span class="syntaxkeyword">@@</span><span class="syntaxdefault">xnote </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> model</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">add_note </span><span class="syntaxkeyword">@@</span><span class="syntaxdefault">notetext</span><span class="syntaxkeyword">,</span><span class="syntaxdefault"> 0.01</span><span class="syntaxkeyword">,</span><span class="syntaxdefault"> 0.99</span>

But if I put this code in booleanhelper.rb it only runs when the user invokes it.
While it has to run all the time.

I've also read something about Sketchup::EntityObserver. Is that relevant in this case???

Thnx for your help

Well, for those who work in Imperial units==inches, it would be cool if you could set the scale factor to overcome the small faces problem but type in the VCB the same numbers as you would if you had not scaled it. Basically, to do away with a bunch of mental math for every value. When finished, reset the scale factor to 1. There's a flaw here somewhere??

Hi mitcorb,

That's a nice idea, but I have no clue to achieve it..

Indeed, the script I'm working on scales up as much as you want and than scales everything down to scalefactor 1.
In scaled up state there's a screen-note reference to the actual scale-factor.
