ah, ok. Another thing to note is that I only tried 3d export, and I only exported a model that was drawn in 2d. So I have not tried 2d export at all. Perhaps it is not working. I'll check it on my machine when I get a chance, but my guess is that I will get your same results - no consutruction geometry. Chris EDIT: I haed acciedntaly mistyped a 3d and 2d....it is all typed as it should be now.

@unknownuser said: Try one of these "</script>" after lets say every 5 or 6 thousand lines. I'm self-employed and darn sure my crab apple boss will fire me if I ever get to 5k lines in a JS file.

@adamb said: I'm sure what Fredo meant to say is that its not good practice to overload (or to some degree) extend a built-in class. Its very good practice to derive from / subclass an existing class to create a specialization you may want. Adam Thanks Adam, this is exactly what I meant. Somehow, the best would be that we restrict the possibility of name clashing only at Module level, which implies that all scripts are alway encapsulated within modules, so that it is easier to control.

@redinhawaii said: I know little to nothing about rubies, but it seems there is a need and maybe there is a way to create rubies for door and window schedules, note keys, lots of useful tools for the creation of working drawings in SU/LO. is it possible, is it practical, who knows rubies well enough to understand the issue? aloha red Don't be put off by the topic title but is this the kind of thing you have in mind? If so can you find someone who would be willing to collaborate on a Mac version as I have only a PC? Chris

dear mates ...I havn't poblished the process yet...so if you are interested to do a co-work plz email me at : majid - ye ga negi (at) yah... com so that i could share you the process

Hi Rob, All we can go by is the API docs - which say nothing about being able to specify options on exporting. It just doesn't appear to be supported. http://code.google.com/apis/sketchup/docs/ourdoc/model.html#export

Chris, Thanks so much for the help, the revised script works beautifully. Proof positive that I was and still am in way over my head. Rob

@jim said: One technique I have used is to pass the name of the Ruby callback to the Javascript. In many cases, you can use a single Javascript function to call any number of Ruby callbacks. Neat trick, and that tells me exactly what I wanted to know. Now where to we go to get the docs to say "add one or more callbacks ..."?

@chris fullmer said: It has to be put into a class and you have to instantiate the class as a tool. And you also have to attach an observer to the Sketchup object. Check out the full example in the introduction paragraph on that page. It shows better how to use it in context. Chris Apart from onQuit is broken on Mac OSX which is annoying. Also be aware that these "stuff has finished / been deleted" generally get invoked after the fact so don't expect to get useful info from the objects in question. Adam

@rickw said: If you give all your form fields an ID, you can reference them in ruby without relying on the info passed in the callback. In fact, there are times I don't pass any data in the callback itself, instead using dialog.get_element_value("myfield") to access the information I need. I only pass the info through the callback if the info is limited to one data set, and then only occasionally. Excellent tip. Thanks.

Even better: Found the defintions.load method that will load the model into the list of definitions which then loads the materials.

You need to keep applying ' parent.transformation' to it... If it's being edited the ' model.edit_tranform' helps...

Ok, Thanks Chris. Of course that is not the answer I wanted to see, considering all of the possibilities that have arisen in this forum. But, you never know...

I also just found this page that might help. http://code.google.com/apis/sketchup/docs/ourdoc/material.html

Think I need to look over my scripts again. Review the ruby code.

I like that you had to come back and refute your own statement Jim Chris

@tig said: Sorry - I made a typo, try this... there was loose ) after entities ! Sketchup.active_model.active_entities.each{|e|e.explode if e.class==Sketchup::ComponentInstance} wewt! thanks man that worked a dream. ive spent so long on this thanks

Built into core Ruby already... Time.now etc, see Ruby http://www.ruby-doc.org/docs/ProgrammingRuby/html/ref_c_time.html et al...

I'm glad they fixed it. I remember reporting it as a bug some time ago.
