Is anyone aware of a way to redraw a group of components or the entire model in one shot? I am finding that individually selecting and right clicking to redraw is tedious and it’s easy to miss a component in large models…

Sketchup.active_model.selection.grep(Sketchup::ComponentInstance).each do |s| $dc_observers.get_latest_class.redraw_with_undo(s) end Open the Ruby Console (Window) and paste

This worked great. Added it with toolbar editor as an icon. Select the entire model and execute. Works like “regenall” in Autocad. Thanks!!

Hello Mike. Would it be possible tor run this script every time I click on DC using onClick tool? Thank you.

[image] mozarov: Would it be possible tor run this script every time I click on DC using onClick tool? I think (but am not sure) that the DCInteractTool will do a redraw for the single instance clicked, when it is appropriate to do so. (If it does not, when it should, please open a bug report in the Technical Issues > SketchUp category.) As to making it work upon ALL DC instances in the model, the answer is NO. This tool is part of Trimble’s proprietary (and closed source) Dynamic Components extension, and changing it is a “no-no”. Regardless, it also is not a good idea to modify a tool that acts upon a single object, to affect multiple objects. There is a single instance redraw command in the right-click context menu (if you right-click on a instance that is a DC.) Code to add a right-click command to redraw all instances of the right-clicked instance’s definition : UI.add_context_menu_handler do |context_menu| ss = Sketchup.active_model.selection if defined?($dc_observers) && ss.single_object? && (ss[0].attribute_dictionary('dynamic_attributes') || ss[0].definition.attribute_dictionary('dynamic_attributes')) context_menu.add_item("Redraw all these DCs") { dco = $dc_observers.get_latest_class ss[0].definition.instances.each {|i| dco.redraw_with_undo(i) } } end end (And no we cannot put the command on the DC edit submenu. The API does not give access to previously defined menu objects.)

Thank you very much for info. I will try to get my head around it. Thanks again

[image] DanRathbun: UI.add_context_menu_handler do |context_menu| ss = Sketchup.active_model.selection if defined?($dc_observers) && ss.single_object? && ss[0].attribute_dictionary(‘dynamic_attributes’) context_menu.add_item(“Redraw all these DCs”) { dco = $dc_observers.get_latest_class ss[0].definition.instances.each {|i| dco.redraw_with_undo(i) } } end end Yep that was easy (because you’ve wrote all the code :slight_smile: ) Just pasted into .rb file and now menu option is there. So there is no script that listens to interact tool being clicked on DC? I am just in the beginig of getting involved with ruby.

Was a mistake in the first code post. Fixed it (above). Ie, I had to check both the instance and the definition for a DC attribute dictionary. [image] mozarov: So there is no script that listens to interact tool being clicked on DC? There is a ToolsObserver but it did not work all that well for native tools in the past. However, this is a RubyTool and in a very recent release the Ruby tool names are now able to read by the observer. (In the past we’d only get "Rubytool" or something similarly worthless.) I do not think the engine calls ToolsObserver#onToolStateChanged for Ruby tools. Also, with the 2016 release, observers were overhauled cache up their callback queues and then do them all at once at the end of the tool’s action. All in all, it’d be easier to write your own “Redraw” click tool to do this.

Thank. But the code only works with one component. If you select 2 or more components, there is no right-click redraw menu.[111] [2222]

[image] KScher: But the code only works with one component. Yes, I wrote it this way.

@KScher & @mozarov Here is a revised edition that will work on multiple selection … # Redraw all selected (and siblings) UI.add_context_menu_handler do |context_menu| ss = Sketchup.active_model.selection if defined?($dc_observers) && !ss.empty? insts = ss.grep(Sketchup::ComponentInstance) if !insts.empty? dynatts = 'dynamic_attributes' insts.select! {|i| i.definition.attribute_dictionary(dynatts) } if !insts.empty? cdefs = insts.map(&:definition).uniq dco = $dc_observers.get_latest_class context_menu.add_item("Redraw ALL sibling DCs") { cdefs.each {|cdef| puts "\nRedrawing Instances of: \"#{cdef.name}\"..." cdef.instances.each {|i| puts "Redrawing ... #{i.inspect}" dco.redraw_with_undo(i) } } } context_menu.add_item("Redraw ONLY selected DCs") { puts insts.each {|i| puts "Redrawing Instance of: \"#{i.definition.name}\"... #{i.inspect}" dco.redraw_with_undo(i) } } end # if DC instances were selected end # if component instances were selected end # if DC loaded and something is selected end # context menu handler block

Thanks Dan! This helped me a lot!

This was offered as a snippet, not an extension.

Please go to the linked topic, then please learn how to do simple things for yourself.

Creating a ZIP file and renaming the filetype to RBZ is rather simple, IMO.
