I expect that SketchUp reads these json files as it starts and writes out revised copies as it quits. So, if you edit the file while SketchUp is already running, SketchUp will not see the changes and will overwrite with its in-memory version when it quits. You need to quit SketchUp before editing any preferences files.

@tig said: C:/Users/USERNAME/AppData/Local/SketchUp/SketchUp 2018/SketchUp/**PrivatePreferences.json** For example, for the "ExtensionStore" toolbar info, you need to find the entries using some grepping and parsing/splitting... for the toolbar "RubyWorkspace\\ToolbarsUser-Bar8"; { > "BarID"; 59661, > "BarName"; "ExtensionStore" > }, and from its BarID, its status later on "RubyWorkspace\\RubyToolBar-59661"; { > "Columns"; 0, > "DockBarId"; 0, > "Visible"; 1 > }, and for its main dialog details "WebDialog_SketchUcation ExtensionStore"; { > "Height"; 918, > "Left"; 11, > "Top"; 84, > "Width"; 862 > }, for this kind of entry note that another 'prefix' might apply for the newer HTML dialog type - test it.. Great！ Many thanks！ wikii

@mingteck said: simple acoustical modelling It depends on what you mean by simple. Using standard formulas based on volume and surface area by absorption is one thing, much past that and the calc time might be a bit long...

Look in ~/Library/Logs/DiagnosticReports

Thank you for your help! I will analyze the Selection Memory Plugin and post the method if I find it.

Nice - in V18 the option hashes are added for several file formats. http://ruby.sketchup.com/file.exporter_options.html

Thank-you for the example and explanations.

Thanks for the links. I think these are a bit too advanced for my needs this time. I simply want to clear all attributes on a selected component (and nested components). I kind of thought it was a one liner script.

I think it is possible to use "face.classify_point(pt)" method to find/select entities, that "touch" some face. For intersection I would recommend a method "intersect_line_plane" from Geom class. Face plane can be simply obtained like "face.plane", edge line like "edge.line", then it is possible to get intersection point like "Geom.intersect_line_plane". Finally it might be useful to make sure that intersection point lies inside of a face boundary using "face.classify_point".

I got it working. I used the ruby-c-extension-example to create a visual studio 2017 project and compiled it. You can find the VS2017 project in the link and compile it or use the so in releases if you have Sketchup 2017 x64. https://drive.google.com/open?id=1Ulz8sNDuyg2dY9Yy1vIW_thEOhAtIq2L

**They always told me to be persistent and I thank all those who gave me this advice. Here is the method to remove all hidden sub-components in a parent component: def supprimer_tous_les_sous_composants_selection(instance) children = instance.definition.entities.select { |e| e.respond_to?(;definition) } children.each { |c| supprimer_tous_les_sous_composants_selection(c); c.erase! if c.hidden? } end supprimer_tous_les_sous_composants_selection(Sketchup.active_model.selection.first) Here is the method to remove all the dynamic attributes of all the components present in a selection: def selectionner_tous_les_sous_composants_selection(instance) children = instance.definition.entities.select { |e| e.respond_to?(;definition) } instance.model.selection.add(children) children.each { |c| selectionner_tous_les_sous_composants_selection(c); } end def supprimer_tous_les_attributs_dynamiques_selection mod = Sketchup.active_model sel = mod.selection sel.each{|s|s.definition.attribute_dictionaries.delete("dynamic_attributes"); sel.grep(Sketchup;;ComponentInstance).each{|i|i.attribute_dictionaries.delete("dynamic_attributes")}} end def desactiver_toutes_les_selections mod = Sketchup.active_model ent = mod.active_entities sel = mod.selection instances = sel.grep(Sketchup;;ComponentInstance) sel.clear end selectionner_tous_les_sous_composants_selection(Sketchup.active_model.selection.first) supprimer_tous_les_attributs_dynamiques_selection desactiver_toutes_les_selections You can test these methods directly with the ruby console, after selecting a dynamic component. You will notice that all hidden components and dynamic attributes will be removed, even if they are nested at multiple levels. Thank you to everyone who helped me. See you David**

**I ended up bypassing the problem by selecting a different definition than "handles" in method 2. I asked to select the IKEA definition, which corresponds to the furniture that contains the facades and the handle inside. def ikeaCI(ents) sel = Sketchup.active_model.selection ents.each do |e| if e.is_a? Sketchup;;ComponentInstance sel.add e if e.definition.name=~/#{"IKEA"}/ ikeaCI(e.definition.entities) end end end This is possible because I specified the definition of the highest components of the hierachie. Is it possible to select the highest components of the hierarchy without specifying the name of that definition? Thank you TIG for your method that allows me to redraw the visible handles. **

Thank you Dan. I will analyze all your information in detail.

Is there some reason this is in the Developer forum?

Our API into the dev tools area has the ability to make analytical info

It's wonderful Pixero. Well tried Pilou, but these are the methods and ruby class for SketchUp that interests me. I am happy to find this good old API.

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.) See this thread: http://sketchucation.com/forums/viewtopic.php?f=180&t=67235

I think I figured it out. Enabling transparent mode for an operation will simply merge it with a previous non-transparent one, regardless if the previous operation is active or not. So, even this should work: model = Sketchup.active_model model.start_operation('Main OP', false, false, false) # A placeholder for all sub operations model.commit_operation x = 0 while (x < 100) model.start_operation('Sub OP', true, false, true) # Do some crazy geometry manipulation, # that I don't want the observer to respond while I'm doing it... model.commit_operation # Committing operation will allow the observers to respond and update view properly. # Do something involving view, like exporting proper view into images # Increment counter x += 1 end Edit: Nevermind. transparent flag is limmited to 100 operations. After that it turns into a normal operation, flooding the undo stack. Running one operation with ui_disable set to false does update the view properly, so I'll stick with it, but it's slow...

Hi, I was not expecting it to be that difficult and don't think its practical anymore to use custom fonts on my plugins. Maybe I'll start looking into drawing images again. Thanks for your help!

When you iterate a collection - like pages, or selection or entities, and change that collection's contents - e.g. by deleting something - then you get issues because the collection changes as a result. BUT if you 'freeze' the collection, but using .to_a OR perhaps you collect items, which are then deleted afterwards, after you exit using the collection... then it avoids the issue.
