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.

There is a link to this blog post in the WebDialog docs, but the link is broken. Is this an appropriate place for an item like this?

@chris fullmer said: So if you ever hit sort by color, it will be on that next time you open SU. Beautiful! No more confusion here, I was sorted by color (whatever that means). Now I'm sorted by name, as everyone has been saying.

Well, Pilou: My version of this plugin just sits there and I have tried all combos of group, no group, select all, select some, select none and right click select operation. No results. Just for your info. mitcorb

No, it looks like you can do "only" export a 3d model, or write an image from a plugin. Thanks.

Thanks Adam. I still don't understand why sum (which is a Float)shown as 1 instead of 1.0 Might the .inspect method be over-ridden?

Thanks Gaieus, and Matt for the script, it's very useful. But could you do it another way? This script just change the unit from model info... My idea is display those units in another measurement window that you can compare more easily. Thanks.
