(2) You are wasting time pushing objects into the selection set.
This is not necessary in order to modify them.

(3) Instances do not "own" any nested components. Definitions own nested objects.
So you should be collecting a set of IKEA definitions, and then searching the definitions entities collection(s) (in that set,) for hidden objects.
When a definition has a child object that is hidden, it will be hidden in ALL of the definition's instances.
When you delete a hidden object from a definition, ALL of it's instances will have that child object deleted.

(1) Why are you putting quotes around IKEA ? (The regular expressions are themselves specially treated double quoted strings.)

Dan Rathbun

There are some code examples here:

Selecting Specific Entity, Group or Component (By Name)

Not sure if it is on the ruby end or if can be done in c. Is there a way to find a specific component in a model by its definition? Also this is from the ruby api. If [0] assumes the first entity, is there a way to get …

SketchUp Community (forums.sketchup.com)

These examples use the == but you can use regular expressions:
http://ruby-doc.org/core-2.0.0/Regexp.html

begins with: =~ /\A#{name}/

Or the specific string "Handle" at start of string followed by: an optional whitespace character, underscore or dash; followed by a literal pound sign (which I escape just in case);
followed by an optional whitespace character; followed by one or more digit characters; just before the end of the string:
=~ /\AHandle(\s|-|_)?\#\s?\d+\z/
... and to make it non-case insensitive we can add a "i" switch at the end outside the slashes:
=~ /\AHandle(\s|-|_)?\#\s?\d+\z/i

If you are using Ruby 2.0 or higher you can also use the String#start_with?() method:
http://ruby-doc.org/core-2.0.0/String.html#method-i-start_with-3F

inst.name.start_with?('Handle')
... or for case insensitive convert to a title:
inst.name.capitalize.start_with?('Handle')

Scott Lininger left Trimble/SketchUp several years ago to start his own company. (He is unlikely to see or reply to your question. Ie, this topic thread is at least 7 years old!)

There are more recent threads on making custom DC functions (but you should not publish any custom changes.)

model = Sketchup.active_model
tool = model.select_tool(nil)

The select tool is activated if you pass nil to the select_tool method.

See this thread as well:

For SketchUp versions 2016+ they added new methods for window selection that can be used when writing your own Ruby tools:

So I am trying to align the Global Axes with a face to create a bounding box that matches the face plane. Then reset Global Axes to Default

It occurs to me that you really want the maximum 2d extents of the face, and really it might best be done virtually rather than modifying the geometry of the model.

Get the array of vertices in the face's outer loop.
Iterate that array mapping the vertex positions to a new 2D array.
(The first vertex should be put at coords 0,0. BTW, you can transform points if you have [or can get] the transformation of the original face. Ie, get the vector from the first vertex to the 2nd and use it to create a transformation for the face if you must.)
Lastly, get the max X and Y value for the 2D box's height and width.

xaxis = Geom;;Vector3d.new(3, 5, 0)
> yaxis = xaxis * Z_AXIS
> Sketchup.active_model.axes.set([10,0,0], xaxis, yaxis, Z_AXIS)

when I use this API example I get the error message:
undefined method ‘axes’ for #Sketchup::Model:0x9815c70

The Sketchup::Model#axes() method and the Sketchup::Axes object class are only available with SketchUp version 2016 and higher.

You can never actually change the global axes. The global origin and axes are always where they are. (They are referenced via global constants ORIGIN, X_AXIS, Y_AXIS, and Z_AXIS. **Do NOT attempt to reassign these constants!**You will only result in confusing other extensions and plugins.)

The axes method and class changes the drawing axes, which is a temporary user axes that native tools honor, and plugins can honor IF they are written to specifically use the drawing axes. (Extension code will not use the custom drawing axes by default.)

Basically I'm trying to prompt you to learn how to read Ruby error and backtrace messages.
“filename:lineNo: inmethod”‘ or “filename:lineNo.”`

Okay 95% of that just went over my head, but I'll try and decipher into terms I can understand.

Data validation - Wikipedia

(en.wikipedia.org)

An example in Ruby of testing if an object reference is pointing at an object of a certain class:
if obj.is_a?(NilClass)
... or ...
if obj.is_a?(Float)

An example in Ruby of validating that an object reference call responds to a certain method call:
if obj.respond_to?(:methname)
... and testing for the "asterisk" method specifically:
if obj.respond_to?(:*)

@medeek said:

But why would this error only be raised for SketchUp running on MacOS and not Windows?

I don't know (offhand) as I avoid Macs myself. (But OSX and MS Windows use different sets of keycodes.)

Actually, looking at the backtraces (in your original error listing) the errors are kicked off by a LButtonDown keypress, but are occurring in the `` create_timber_geometry()`' method, lines 1064 and 1355.

Dan Rathbun

@medeek said:

The error codes posted above.

... are occurring (according to your error messages,) in " medeek_roof_truss.rbs", line 5726, in callback method onLButtonDown.

In the first you are calling a *() method upon an object that is referencing the global singleton nil object. Since the NilClass does not have an "asterisk" method, a NoMethodError is raised.

The second method is caused by your code expecting a Float object, but getting a String object instead.

The answer is simple. Whenever an object reference could reference disparate types (classes) of obejcts, use a combination of type validation and Ruby rescue clauses with the onLButtonDown callback method.

@sdmitch said:

I found this ( view#camera=) in the API but I have yet to get it to be recognized.

See:
(SketchUp Developer forum): Setter #view.camera= Testing with Second Transition Time Argument

@sdmitch said:

Perhaps it has been removed or never implemented.

The API docs are a bit confusing.

The view#camera= method is an overloaded method, which can be used two ways:

with a single Sketchup::Camera object argument
with a single Array argument of: [ Sketchup::Camera, Float ]
(The Float being the transition time.)

If you attempt to pass two arguments, of Sketchup::Camera and Float, the API ignores the second (time) argument and you get behavior #1. (Ie, a silent failure from what you'd expect.)

Dan Rathbun

@sdmitch said:

I'm still trying to solve the transition problem.

When you manually change scenes (and the model does not have specific transition and/or delay properties assigned to individual page objects,) then the model's global animation transition and delay settings are used.

Global settings are via:
Window > Model Info > Animation

Global transition and delay is accessible via the model's options provider objects.

model = Sketchup.active_model
manager = model.options
popts = Sketchup.active_model.options["PageOptions"]
popts.each {|o| puts o }
#=> ShowTransition
#=> TransitionTime
sopts = Sketchup.active_model.options["SlideshowOptions"]
sopts.each {|o| puts o }
#=> LoopSlideshow
#=> SlideTime

A per scene page settings interface is not yet implemented, but I think I myself and others have requested it as a PRO feature request. (I believe it should be a Pro only feature myself.)

You can easily write a script to set per page transition and delay.

I also think some of the better animation extensions have UI interface to set per scene transition and delay. (I think Smustard's does.)

Let us know if any of the suggestions work.

Read the old "Pick-Axe" book's chapter on writing a Ruby extension.

Programming Ruby: Extending Ruby

Take note of the Ruby C-side functions:

rb_eval_string( *string_to_eval* )* rb_funcall
... described in section "Evaluating Ruby Expressions in C"

okay, a dedicated C side Ruby book is also now available:

Or single object extension via mixin module (as shown above.)

unless bb.extend(BB_Volume).volume == 0.0
  # do code here
end

Or if only supporting Ruby 2.x+ SketchUp versions, you can use class refinements that are only active within your files.
See: http://ruby-doc.org/core-2.0.0/doc/syntax/refinements_rdoc.html

You missed the point John, he's doing neither. He is simply leaving the droplist and grabbing the window caption bar and moving the entire window. This is leaving the droplists behind (as if torn off) as shown in the screenshots above.

My attempt to fix it would detect when the mouse leaves the body of the html document, and blur the <select> element hopefully making it close it's droplist.

Also I moved the form while the drop down list is open and now you can't tell which drop down I was in. The difference is IE closes the drop down when you click and drag the form - chrome does not.

Let us try some tests to see if we can get Chrome to close the <select> droplists.


 <body onmouseout="document.blur();" onmouseover="document.focus();">

I'm hoping this will cause the current active selection element to lose focus and have it's blur event fire.

If this does not work, then perhaps keep track of the current object that has focus:


<!DOCTYPE html>
<html>

    <head>
        <script>
            // Global variable;
            activeObject = document.body;
            previousObject = document.body;
            
            function setActive(obj) {
                activeObject = obj;
            }

            function clearActive(obj) {
                activeObject = document.body;
                previousObject = obj;
            }

            function blurAll() {
                if activeObject != document.body {
                    activeObject.blur();
                    if activeObject != document.body {
                        clearActive(activeObject);
                    }
                }
                document.blur();
            }

            function reFocus() {
                document.focus();
                if previousObject != document.body {
                    previousObject.focus(); // calls setActive(previousObject)
                    previousObject = document.body;
                }
            }

            function CheckKey(e) {
                var code = e.keyCode ? e.keyCode ; e.which;
                if(code === 13) {
                  alert("You press Enter key.");
                }            
            }

            function SubstanceChangeHandler(val) {
              alert("New substance chosen; "+val);
              txtTest.value= val;
            }        
        </script>
    </head>

    <body onmouseout="blurAll();" onmouseover="reFocus();">
    
        <input name="txtTest"  type="text" id="txtTest" onkeyup="CheckKey(event)"/>

        <select onchange="SubstanceChangeHandler(this.value);"
                onfocus="setActive(this);" onblur="clearActive(this);">
          <optgroup label="Alkaline Metals">
            <option>Lithium (Li)</option>
            <option>Sodium (Na)</option>
            <option>Potassium (K)</option>
          </optgroup>
          <optgroup label="Halogens">
            <option>Fluorine (F)</option>
            <option>Chlorine (Cl)</option>
            <option>Bromine (Br)</option>
          </optgroup>
        </select>

    </body>

</html>

If this scenario works, you can set the onfocus and onblur handlers for all <select> elements via an iteration loop after the page loads.

Also the Enter key doesn't trap while you are inside a drop down list.

But when the user (in CEF) hits ENTER on an <select><option>, that changes the selection does it not ? And therefore it should fire the some event ?

I just tested in normal Chrome and the ENTER key works fine.
