Thanks Dan. I'd be willing to bet that save_delete_material method doesn't actually search all the faces, only those in the top-level definitions. I had thomthom help me a long time ago to write a recursive function to iterate ALL the faces, so I think I'll piece this together from that...

@tig said: You don't need to find those [even if you could] because the Zoom Extents on a single car does that in the view. Of course depending on your screen's current proportions and the exact view of the car you will get some 'white space' around the image. If you don't want all images to be the same size then that 'white space' is best removed with an Image editor [like Gimp] - where you can batch-open each file in turn and Auto-Crop it and save, to ensure that each car occupies as much of the image as possible... thanks for your tip! maybe I will do that in the future.

you sent me on the right track, thanks sdmitch

I have been working on something similar and have had some success with Dijkstra's algorithm. This is my first project with SketchUp and Ruby so my plugin has been built by trial and error and isn't very pretty. The Calculate Shortest Routes command in the Plugins menu writes the results to the Ruby Console window. There is another command that writes the results to a .csv file. dijkstra.rb dijkstra_example.skp

@thomthom said: @driven said: So my advice to the OP is please inform you users if you assign/re-assign 'shortcut' keys for them. Or rather, give them the option to decline such change. Violating this rule should be grounds for quarantine, IMHO.

Christ Fullmer you are a genius!!! This transform SketchUp into the best painting application in my opinion...I will see If I can expand this & add new features to make it even better. I am so excited!...again thanks!

Ok, I was focusing to much on the NoMethodError. Glad you sorted it out!

Thanks to all for the quick responses

@ruggiero said: I was defining generic arrays and expecting them to behave like geometric vectors! Why should they? The SketchUp API does not override Array#+(), so you need to consult the Standard Ruby dictionary. (Either online, or the downloadable CHM. Follow the link in my signature, to more links in the Ruby Resources sticky thread.)

@juantxo said: Something similar occurs if you close dialog in a callback: On the PC, this might work: my_dialog.add_action_callback("test") do |web_dialog,param| web_dialog.close end my_dialog.set_on_close { UI.messagebox('NOT DISPLAYED') } AFIAK, set_on_close is still bugged on the Mac

Did you ALSO install TT_Lib2 ????????????? Obviously solid inspector has a library dependancy on TT_Lib2. Did you read the solid inspector post for dependancies, and install all those needed ?

Have you tried using UI.start_timer I show an example HERE

Notepad ++ is a good choice. It's quite used around here I think. I use it to. But I don't use bridge. I reload my scripts having robycode editor open all the time during developping. Can't remember why I do it this way Just letting you know there is that option to. @unknownuser said: From your experience is it a good idea to use core ruby classes with Sketchup and I am not sure how it will effect the working of plugin on Macs (Like I said. My experience is poor, so don't take what I have written as solid good advice. I must stress that. I just jump in and ask questions or give advice when maybe I should keep my mouth shut. ) At some point you must use the API ? Doesent matter if youre on Mac or not. What I meant was that if there already exist a method in the API, one should use it. Most likely it will be a faster method then what you will create in Ruby. Automatic Sketchup is really good for getting grasp of transformations and such. But you should really poke around other peoples scripts to get a feel of how to do things.. http://sketchucation.com/forums/viewtopic.php?f=180&t=25305 There are some recent performance tips here. And a few things to avoid.

Actually a EuroZone court found that you can transfer your license. But that was a paid license not a free one. And would most likely only be applicable in that jurisdiction. But alas Russia and some other places don't care what kind of copyright law you write. They do as they please. And I never had any issues with registry keys. Although I run CC cleaner on my registry every few months just to keep it tidy.

@tinhnguyen20 said: What is a normal and can somebody give me an example? The vector perpendicular to and pointing away from the front of the object's plane. See Wikipedia: Surface Normal from which comes this image: [image: 222px-Surface_normal_illustration.png]

Material.write_thumbnail is bugged in its design. If I remember it preserves the aspect ratio but exports the largest dimension no larger than 128px (or something, at least the cause why it fails most of the times is when one dimension is rounded to 0). I'm still searching for the detailed forum post and bug report on this. Don't use it, but use Jim's suggestion with a material applied to a group. It will retain the color shift and colorized properties.

@unknownuser said: What does "reuse the iteration" mean? Hm. maybe my explanations and english where bad. Hash.each{|k, v| v.do something } is called an "iteration", right? Iterate a Hash. Depending on something do the same iteration on other Hash with different values. Seams like waste retyping the same code again.. I know you are asking why I don't pass in a nested Hash, or array and just do everything in 1 go. In this case I just cant.

Any other ways you guys can think of?

@sdmitch said: So even though the global variable retains lts value, the entity it references doesn't exist? I don't know the internals. But as yoou noticed, even when the global variable appears to reference a valid menu object, new items are not added after some short amount of time.

Standard Library isn't compatible with SketchUp Ruby. For instance, the Set class that SketchUp bundle isn't compatible with the STL Set class.
