Modifying Ruby and Sketchup base classes are a big no-no. Some other plugin might require the original behaviour. Instead of modifying the existing - create your own class which inherit the HAsh class and modify that.

@chris fullmer said: Don't forget that refresh is new to 7.1 (or was it 7.0?). Anyhow, it is new and not compatible with older versions... Chris 7.1 http://code.google.com/intl/nb/apis/sketchup/docs/releases.html

I think it's odd that the parser would be sensitive to a newline at the end of the file.

.transform! uses the Group's or Instance's current Transformation and applies the new one (change by a Transformation) .transformation= simply replaces the Group's or Instance's Transformation with the new one (change to a Transformation.) For example, if you use the IDENTITY matrix: entity.transform!(IDENTITY) - no change. entity.transformation= IDENTITY - position, rotation and scaling are all reset.

@huckrorick said: This link leads to lots of dead end links. http://groups.google.com/group/SketchUp-Plugins-Dev Is this still functioning as you describe? Huck That's an old outdated link. This is the current API reference: http://code.google.com/intl/nb/apis/sketchup/docs/index.html

I was pretty sure I'd tried that! But clearly I haven't! ` point1 = Geom::Point3d.new 1,1,1 Point3d(1, 1, 1) point2 = Geom::Point3d.new 10,10,10 Point3d(10, 10, 10) point3 = Geom::Point3d.new 10,10,10 Point3d(10, 10, 10) s = Set.new #Set:0xbd7da68 s.insert(point1) #Set:0xbd7da68 s.insert(point2) #Set:0xbd7da68 s.insert(point3) #Set:0xbd7da68 s.to_a [Point3d(1, 1, 1), Point3d(10, 10, 10)]` Very interesting that it evaluates differently. It compares the values, not the objects. Exactly the kind of solution I was hoping for.

Yes, that is what I'm using, but there are always problems.

@dave wood said: Thanks, again, TIG, I opened the 2D toolbar and couldn't get the help file from there, either. I can open the .htm file directly in the 2D Tools subdirectory. I get a message that the internet explorer can't display webpage. Windows can't diagnose the problem. What is the web browser? Good question, keep in mind you're working with a relative novice.-- The top of the window says SketchUcation Community Forums.- Internet Explorer provided by Dell. Below I've got a couple of Google search "panels" and a microsoft bing search "panel". I didn't have time to look into the commands, but a read some of the instructions. You started to lose me a little with some the info re: how the lines reside on edges, faces, etc. and how the width of the line is affected. I imagine it might be overly difficult to add some illustrations. See, you give the people all this, and all they do is ask for more! Thanks again very much. I'm looking forward to using some of these tools. Are you a Vista 'Administartor' ? The Help htm works in IE and FireFox for me... Strange ? It's easiest to try the tools out in a scrap Model - learn by doing...

@martinrinehart said: @dan rathbun said: What's wrong with the standard included classes File and Dir ?? You can do all that would be desired with their methods. That's all I've done: def cd( path ) Dir::chdir( path ) end Shell Commands are already allowed within Ruby. [Examples for PC win32 platform, but also applies to Mac OSX.] use the %x delimiter, as in: %x{dir *.skp} or backquoted strings, as in: dir *.skp (from: Programming Ruby - The Pragmatic Programmer's Guide) The Ruby Language > Expressions > Single Terms Shell Command. A shell command is a string enclosed in backquotes, or in a general delimited string (page 200) starting with %x. The value of the string is the standard output of running the command represented by the string under the host operating system's standard shell. The execution also sets the $? variable with the command's exit status. [Example - '.c' changed to '.skp';'ls' changed to 'dir'.] %(#BF0000)[filter = "*.skp" files = dir #{filter} files = %x{dir #{filter}}] ! Backquoted strings allow replacement like doublequoted strings ! Expressions > Miscellaneous Expressions**http://www.ruby-doc.org/docs/ProgrammingRuby/html/tut_expressions.html** Command Expansion If you enclose a string in backquotes, or use the delimited form prefixed by %x, it will (by default) be executed as a command by your underlying operating system. The value of the expression is the standard output of that command. ! The output is a String, so any String method can be applied to the expression: Ex: dir.include?('.jpg') returns true if there are any jpeg files in the dir _

Yes, "comp_entities" is the exploded array. OK, so when I see is_a? in this manner, the do loop is "select(ing) the entity(s)" in the array that is a (are) %(#FF0000)Sketchup::Drawingelement. Is it faster (better) then: comp_entities.each do |e| if e.is_a? Sketchup;;Drawingelement comp_new.push e end end Addenda: Corrected as noted below.

Thanks Fredo. It's working now!!!

@unknownuser said: But can't this already be done in SU with the Generate Report function? The problem with the inbuilt report generator is the same as the script referred to above. It is not very flexible, even if you take the option to report on selected components ony, it still includes all the attributes of all the components, and it reports in imperial measurements even if the model is in metric. What I would prefer is a report which is more selective such as the example I detailed above. The problem I am having is finding someone who could modify the above script.

Daniel I agree that a configuration as you provided won't inference snap though similar ones will ! There is a way to find the true intersection of the edge and the arc that would sweep through the rotated end hole's center itself centered on the middle hole... Use my Tangent Tools script. Draw a cline through the desired edge and two concentric arcs [same radius] centered on the middle hole passing through the end hole to be rotated. Select the cline and both arcs. Those arcs will be too segmented to give an accurate intersection with the cline BUT the Tangent Tool > True Intersections will place cpoints at the two possible intersections on the cline and two additional cline guides from the arcs' center to these cpoints. It will also beep and report an error in the Ruby Console since the arcs are concentric and can't intersect with themselves... It's probably best to place the cline and two arcs into group of their own for easy erasure later... Simply use one of the cpoints to rotate the shapes about its central hole's center and snap to... This is convoluted BUT does give an accurate snap cpoint on the edge.[image: NGvj_inferenceonrotate.png]inferenceonrotate.skp

@dan rathbun said: That is because in module definitions, the module statement is a block statement so the word module works the same as begin (after all, the module does need an end.) Thanks for the explanation.

Right - eval gets passed String objects. So before the eval is called, json is a variable which references a String. After the eval, the variable foo refers to a Javascript Object. However, @unknownuser said: To convert a JSON text into an object, you can use the eval() function. eval() invokes the JavaScript compiler. Since JSON is a proper subset of JavaScript, the compiler will correctly parse the text and produce an object structure. The text must be wrapped in parens to avoid tripping on an ambiguity in JavaScript's syntax. var myObject = eval('(' + myJSONtext + ')'); and @unknownuser said: ..If the server is not rigorous in its JSON encoding, or if it does not scrupulously validate all of its inputs, then it could deliver invalid JSON text that could be carrying dangerous script. The eval function would execute the script, unleashing its malice. To defend against this, a JSON parser should be used. A JSON parser will recognize only JSON text, rejecting all scripts. In browsers that provide native JSON support, JSON parsers are also much faster than eval. It is expected that native JSON support will be included in the next ECMAScript standard. var myObject = JSON.parse(myJSONtext, reviver); I believe Chris is using json2.js on my recommendation, which is based on DC's recommendation because it is possible CG's data could come from an outside source. And I would also repeat what TBD said and watch the "Good Stuff" video - at least you will know what to avoid in Javascript to make your life easier.

Did I help, or just confuse you?

Thank you, That did the trick…..hadn’t even crossed my mind. I figured it was something painfully obvious that I was missing. Thanks again, Glenn

@chris fullmer said: I could be way off, but I was thinking it was an optimization thing. I think they are just checking to see if the inputpoint changed, and only if it changes do they refire the draw method. Chris But as the manual says: @unknownuser said: true if a valid InputPoint was picked and it is different than it was before. From that, it sounds like the InputPoint object is performing the check for you. It returns true only if it's different from the last time you called pick.] (Note: I haven't tested that the implementation actually works as the manual says it should. We have enough examples of deviance... )

@martinrinehart said: I've found materials to be so dangerous that I no longer let them near Ruby. face.material = '[Wood_Cherry_Original]' Problem: the face looks like cherry, but model.materials has no cherry. Bug Splat coming soon. face.material = model.materials['[Wood_Cherry_Original]'] If there is no material '[Wood_Cherry_Original]' then model.materials['[Wood_Cherry_Original]'] will return nil, which indirectly means Default Material. I've not experienced any problems with materials using this method.
