@Sklik-Rab said in Ruby Sketchup Programmatic Union of Multiple items: @Dan-Rathbun How to check if @union become nil? To check if the reference points at nil, you can use: @union.nil? which is inherited by Array from Object#nil? To check if the array is empty, you can use: @union.empty?

@sajid1999 This is normal. If you change your PC, the unique hardware ID changes. You can release old seats on this page (you'll need to sign-in)

@hollymichel No, it doesn't read a lot better. You must add the 'code' tag and put your Ruby code inside it. Then the start and end tags [i.e. three back-quotes each: note I put spaces in front here to prevent the forum thinking it was more code... ``` ### ruby code text goes here ``` ] they must both be on their own lines. Which looks like this in the post. ### ruby code text goes here Simplify your process, and make it more complex only when you've got some good results. Trying to do it all in one go is just too difficult. How do you eat an elephant - take small bites !

@EdwardJ82 There are many RB files [unencrypted text] available in the PluginStore, https://sketchucation.com/pluginstore There are also shorter 'snippets' attached to some posts in this forum. You should get very simple examples and try to understand how they work. You also need to understand how the API works... https://ruby.sketchup.com/

This is quite useful for selecting the last object extension. Could there be a variation of this that selects and zooms into the last object?

@dan rathbun said: The C API is mainly written to act upon files. There is only some limited things you can do with "live" models. Currently, the C API cannot be used to modify the active model. You can get the active edit path via: SUModelGetActivePath() ... and from it the transform via: SUInstancePathGetTransform() Thanks, Dan, for the information! I solved it in my code by having a ModelObserver, implementing onActivePathChanged, and passing it to my C-extension code. Even though you cannot modify the active model, you still need to know the edit transformation for some cases. If a user opens a model to edit, if you query the instance transformation, it will be a world-coordinate transformation instead of a transformation relative to the parent. My C code assumes transformations relative to the parent, so I must calculate that using the edit transformation. You probably already knew this, but I'm putting it here for posterity. Cheers, Thomas

@jkoll66 said: I know this post is like a thousand years old, but I was using the "extract_png.rb" from "Jim". It doesn't seem to work in SU2023. I need this to compile a catalogue of all of my components. Is there an updated version out there somewhere? I really need this. Thanks in advance! If you are doing this from within SketchUp, try something like: # SketchUp 2015 or later. def export_thumbnails(source_path = nil, dest_path = nil) # unless source_path && File.directory?(source_path) models = Sketchup.active_model.path if models.empty? models = File.join(ENV['HOME'], 'Documents') end # source_path = UI.select_directory( title; "Select Model Directory", directory; models ) return unless source_path end # unless dest_path && File.directory?(dest_path) images = Sketchup.active_model.path images = source_path if images.empty? # dest_path = UI.select_directory( title; "Select Image Output Directory", directory; images ) return unless dest_path end # Dir.glob( '*.skp', base; source_path ) do |skp| source_file = File.join(source_path, skp) image_file = skp.split('.')[0] << '.png' output_file = File.join( dest_path, image_file ) Sketchup.save_thumbnail(source_file, output_file) end # Dir loop # end ###

@areal3d said: hello, how can i get the whole path as in the pickhelper from a selected instance? You will either need to build an InstancePath as you drill down or get the Model.active_path and add the selected instance to it.

@tig said: In the very first line of your Ruby RB file add this. # encoding; UTF-8 This should ensure your own code is properly formatted. This magic comment does not ensure that the code file is saved as UTF-8 w/o BOM. This must be set in whatever code editor is being used.

@areal3d said: is there any way to controll the position of the ruby inputbox on the screen, just to put it a bit away from the center of the screen? Sorry, Stan. NO the UI.inputbox method always centers the dialog.

@icehuli said: Someone might be interested in using c# and .net stuff. I created a very simple example to write a ruby extension in c#. https://bitbucket.org/icehuli/sucsexttutorial can you guide me to run the sample code

Königsblau = Royal Blue [plain wrong!] Ruby-Konsole = Ruby Console [simply correct]

Is there any way to fix this?

Thank you very much, this is exactly what I'm looking for !

edit: found the filed for the version......upload worked thanx for helping me !!!! stan
