Back to TIG's comment about plural vs. singular names for arrays, here is the way I'm naming things. In this context, the singular terms seem to work better for me, probably because I think of it as the mathematical notation P[sub:2dctu78y]0[/sub:2dctu78y], P[sub:2dctu78y]1[/sub:2dctu78y], ... P[sub:2dctu78y]N[/sub:2dctu78y]. =begin point[N] x-------------x point[0] angle[0] = angle_between vector[N], vector[0] vector[N] \ vector[N] = point[N], point[0] \ \ vector[0] \ vector[0] = point[0], point[1] \ x point[1] angle[1] = angle_between vector[0], vector[1] / vector[1] / vector[1] = point[1], point[2] / / / x point[2] angle[2] = angle_between vector[1], vector[2] =end

"Programming Ruby - The Pragmatic Programmer's Guide" explains it all.

I tried once more, and this time it's listed. (no idea why it wasn't earlier - but at least it's working now.) Very nice feature.

well.. that's embarrassing... actually the "problem" is that i had overloaded "onElementAdded" method.. and put: @service.recent_inherit! entity now i send a new attribute, then it becomes: if entity.definition.get_attribute 'dynamic_attributes', 'imported_entity' @service.recent_inherit! entity end sorry about that and thanks for your time. cheers.

@tig said: Here's how I would do it... Let's first assume that a component-instance has no label. The user clicks on it. It is confirmed as a component-instance. It is also checked for a special attribute, tid=instance.get_attribute("SensorNodeInfo", "tid", nil), in this case it returns nil as it has no label. unless tid > ### add_label_code > else > ### delete_label_code > end The 'add_label_code' will make the Text object, and give it a 'tid', a matching 'tid' will also be given to the picked instance... ` tid=Time.now.to_f+rand instance.set_attribute("SensorNodeInfo", "tid", tid) some code to add the Text object - referenced as 'label' label.set_attribute("SensorNodeInfo", "tid", tid)` Now the instance and its label are pair with a matching [unique] tid attribute. The 'delete_label_code' erases any related 'label', by matching its 'tid'. The 'label' Text object will have been previously given a unique 'tid' returned in the 'instance' match that was NOT nil, so you need to iterate the instances context to get possible candidates, labels_to_go=instance.parent.entities.grep(Sketcup::Text).select{|e| e.get_attribute("SensorNodeInfo", "tid", nil)==tid } then instance.parent.entities.erase_entities(labels_to_go) if labels_to_go[0] Thanks that's very helpful.

those don't sound like issues that were in the latest service release. The V-Ray material information is stored in the material's attribute dictionary in xml format. Multi-Materials have the child material xml included with them.

I know I'm late to the game, but I am just seeing this now. I am wrapping up development of another extension, and will be ready to take up my next project soon. Are you still looking for a developer to make this for you?

I'm wrapping up development on another plugin, and will be available for my next project soon. Are you still looking for a developer to help you create this?

Thanks, I will test this and come back to post the results.

Many thanks TIG, your first code line does perfectly the job. In fact I have many instances of the same component, and each one is differentiated by a unique name. And just by removing s.clear I can make multiple selections, which is exactly what I intended to do. You made my day !!

@dan rathbun said: @kimpastro said: PS: don't know if i'm using the correct terms for elements like: model, entity, modules, etc. Sorry about that. Yes you are misusing the term module. In your examples, "loaded_module" is a "loaded_component_definition". module is a ruby keyword, and a block of code that forms a namespace. Thanks, I'll be careful next time. I'm confusing about module because we use the same term to determine the "master entity" of our projects to our clients.

@dan rathbun said: The origin of the active_model is [0,0,0], which is referenced as ORIGIN.

Wow! This is awesome! It works! Thanks a lot. I almost gave up! Good to know, that there are real experts in this forum who are willing to help. Thanks again.

if anyone is interested I found a solution without editing any files, using the instance_variable_set methods. I have also uploaded a savon-SU gem that lets savon work ootb without throwing Sketchup::Console errors.

b='hop' is the same as: b=String::new('hop') The Ruby interpreter "reads" the literal string 'hop' and passes it to String::new "behind the curtain". = is the reference assignment operator. a="hip" means "the variable a shall reference the string object 'hip'." a=b means "the variable a shall reference the object that b is referencing."

Hello MartinRinehart, I take the opportunity of your thread to thank you for the Edges to Rubies you link in your signature. I found out your tutorial some month ago and pages 15 and 16 made me on the track of animation. Just what I needed to jump into and now I am developing my own code I have just named a class the same of your 'Transformable' in your honour. It's quit different from your but the name makes me remember your excellent tutorial. A thousand of thanks once more. Have a good day Sorry for the sidetrack. Second time today!

You're right about the sidetrack but it's just a small piece of distraction in a flow of coding! and we are not so far from Sketchup as you may see on that website I made for fun. I am a woodworker hobbyist and never get money from woodworking as I spent all my spare time making small furniture for myself - not enough free time for the others! Besides the ruby code I am writing these days is a continuation of the pictures on the website that I would like to animate. May it turn to any plugin ? wait and see... Have a good late afternoon

@jim said: "A".ord http://ruby-doc.org/core-2.0.0/String.html#method-i-ord Thanks for the info and especially the link.

This code is not exhaustively tested, but it should give you enough ideas: model = Sketchup.active_model model.start_operation('Unglue', true) insts = model.selection.grep(Sketchup;;ComponentInstance) insts.each{|inst| inst.glued_to= nil } model.commit_operation One step undo-able... It un-glues all selected component-instances.

@sonjachr said: Many Thanks, this works, I really appreciate your help! I feel ashamed as I should have found the solution by myself. I will try to work harder on my Sketchup/Ruby knowledge, but I will never become an expert as you are. Great, glad I could help.
