@didier bur said: Partial answer here: http://www.postal-code.com/mrhappy/blog/2007/02/01/ruby-comparing-an-objects-class-in-a-case-statement/ and here http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/3d83faf049160e58 This works: case Sketchup.active_model.selection[0] > when 'Sketchup;;Face' > puts "face" > ... The simplest the best ! So in your case def test() case Sketchup.active_model.selection[0] when Sketchup;;Face puts "face" when Sketchup;;ComponentInstance puts "instance" when Sketchup;;Group puts "group" when Sketchup;;Image puts "image" when Sketchup;;Edge puts "edge" else puts "something else" end end should work ???

Thomthom One week later... Here's v1.4 http://forums.sketchucation.com/viewtopic.php?p=271170#p271170 Which now supports copying/arraying punching-components etc... It has a plethora of convoluted observers and linked attributes BUT it now works...

@honoluludesktop said: I see that your version of DOS is 6.1. Is this its original release, or the one that came with your WinOS? Which machine were you on at the time? I have a copy of DOS 6.1 (left over from the good old days) installed in a VPC. FYI ... DOS 6.22 came out at the same time as Win 3.11 for Workgroups (I still have my disks and manuals as well.) DOS 7 was distroed with Win98 (not sure about Win95.) Win 2000 & up are NTFS not DOS. BUT ... you misread the image. It is the Windows ver that is displayed, not DOS. Win 5.0 = Windows 2000 Win 5.1 = Windows XP Win 6.0 = Windows Vista Win 6.1 = Windows 7

The reason I ask is because I'm very new to sketchup-ruby scripting. I enjoyed making pipe sculptures, so I got the free version of 3SKENG when it was avalable. (it's not available for a free download anymore :evil: ) So I said why not give myself a challenge and try to make 3SKENG myself. I just wanted the plugin to create the geometry, without any mouse gestures or vcb. I allready knew how to use UI.inputbox, so I decided to just use that. (does anyone know how to redefine the defaults to match the last usage?) I was hoping someone knew a simple lathe tool. So far I'v got it to make all the circles in the curve, but I don't know how to connect them. PS. Sorry I yelled. :ashamed:

There'a a major drawback to using the API "default" methods. That is they did not give us a "remove_default" method. This means the Win Registry or Mac plist can become cluttered with old 'orphaned' settings for plugins that are no longer used. Many authors (TIG is one I think,) that instead write out their own settings file in the plugin subfolder. I think he has posted code snippets in other topic threads. Basically you write out a string report of your settings Hash to a text file, using the inspect method. To reload it, you read the file into a String object, and then eval() the string inside the context of your module, assigning it to a var, which should become type Hash after evaluation.

@dan rathbun said: ...........refers to the module namespace that you are defining the method within......... OK, I get that. Thanks.

@alexmozg said: > def Sketchup;;exit > model = Sketchup.active_model > model.save "temp_model.tmp" if model.modified? > Sketchup.send_action 57602 > end#def > Model doezn't realy save. Do NOT use exit as a method name !!! It is already defined as a global method by the Kernel module (and so is inherited by ALL classes and modules.) exit() Initiates the termination of the Ruby script by raising the SystemExit exception. Also runs any at_exit block methods before termination.

Great, Thanks I can experiment.

@dan rathbun said: @thomthom said: Will have to look into this. OK good.. get with John (driven) directly. Since I don't have a Mac, I cannot recreate his situation. Your in a better position to help him (he wants to use Jim's Mover plugin with 1 click.) I'm wondering if one of those shell commands (in the forum topics would work,) like ?? %(#4000BF)[defaults write com.apple.Safari FocusFollowsMouse -string YES] OR %(#4000BF)[defaults write com.google.Sketchup FocusFollowsMouse -string YES] OR whatever... Found this: http://mactips.dwhoard.com/mactips/x11-and-terminal/x11-click-through Doesn't modify the focus follow mouse behaviour, but allows clicks to go through at first click. But I'd prefer to find a per-window setting instead of a per-application setting.

Thanks guys.

@unknownuser said: I agree. What we need is that everything what you can do with SU is also supported in the API. I don't know why there are some parts that aren't supported (sectionplanes, Export 2D graphic (dxf), ...) Dimensions, several Material & Layer methods ... the list goes on...

The pushpullbar project linked to was actually developed in Rhino with Rhino-specific scripts so while some of the info will be useful, you will have to look elsewhere for your answer...

Thank you. Now It works fine.

@jim said: ............ I use a C:\Plugins folder that is used by all the versions of SketchUp I have installed. It's much easier not to have to copy and paste an entire folder of plugins from one version to the next............ Good idea, even though there are exceptions.

I went from here: [image: Temp02.png] to here by Geom::Transformation.new(pt, axis, angle): [image: Temp03.png] then to here by ent.transform_entities(transform,ent1,ent2,ent3): [image: Temp04.png] But how do I do step 2 for a component rotated on all three axis?
