[Plugin] Lamella Roofs
-
Will the routine allow the creation of in-line lamellas, without the slight offsets?
Thank you much for sharing, Tim.

bookmark, what is that?
i usually post, then it is in my threads.
will have to try to bookmark...
-
reply to keep this in my list of threads.
i'll peek back once the ruby gets improved.nice looking plugin.

Dear Tim,
You and your colleagues are to be congratulated on your achievement. How long did it take start to finish, and did you have building experience before starting the project?
Kind regards,
Bob -

Simple answer, no. The plugin assumes the use of dimensional lumber and common bolt connectors, as in the original Zollinger concept, and in recent examples like the Rural Studio dog shelter http://apps.cadc.auburn.edu/rural-studio/Default.aspx?path=Gallery%2fProjects%2f2006%2fhalecoanimalshelter%2f. But it's a natural option, and easier to model. Thx for the (implicit) suggestion.
PS I'm attaching a brief monograph on the underlying geometry.

This is actually a one-man show. I built a lamella roof (the one shown at the top of the thread) some years back, based on a crude, and actually wrong Excel model, but only worked out the exact geometry last year. Writing a plugin involved learning Ruby (OK, it shows!), and grappling with the SU documentation, which I have to say I find opaque in many ways. The plugin probably took about three months to work out.
I'm not a builder at all, but I've done some simple construction work, if dry-stack walls count.
-
Great plugin Tim!!

I've corrected the plugin to reflect the very helpful community comments, and fix some minor errors in the way curved surfaces were being generated. Both the revised plugin and documentation are embedded in the original post to make them easier to find.
I'm still puzzling over a couple of issues. First is the odd failure of the intersect_with method in at least one circumstance. (Posted elsewhere http://forums.sketchucation.com/viewtopic.php?f=180&t=46714). This wipes out a couple of faces in a lamella, but is rare, and easy to fix manually. Second, the geometry is off by a small (< 1mm) amount in terms of the components not lining up exactly. It doesn't feel like a rounding error, so my calculations may be incorrect. Practically this is not significant.Thx all, and TIG and Thomthom especially, for your advice.
-
Really appreicate the plugin... and even more so Tig and Thom for always checking all these plugins out for us and warning us before installing them.
-
I've updated the plugin to allow the creation of a diagrid lamella roof, where the lamellas are co-planar, following brookefox's suggestion, and to add some error-checking and spinners on input. Updates are located with the original post.
Under some circumstances the upper surface of the lamella is not created properly, for reasons I still don't understand. The cutting instructions are correct, regardless.
-
Thanks Tim, hope I get to do a project with this kind of roof one day!
-
I dropped the lamella_roof.rb to the plugins folder and nothing happens, restarted SU and is not on the list?
Any one has the same issue.
I also like the big hangars made of concrete by the designer an italian eng-arch Pier Luigi Nervi.
Thanks.
-
What did you expect to happen? Did "Lamella roof" show up in the Plugins menu?
Go back to the Plugins folder and make sure lamella_roof.rb is there with the correct extension and that you didn't put it in some other Plugins folder.
-
pasted in the C:\Program Files\Google\Google SketchUp 8\Plugins.
-
Let's see if I can drag some useful information out of you so we can help you.
And after you close and reopen SketchUp does the plugin show in the Plugins menu? Do you really have XP as your profile indicates?
-
Not shown after reopen.
yes XP
-
Post a screen shot of your Plugins folder showing the file installed. Make sure extensions are being shown.
And you did actually close SketchUp and reopen it? You didn't just minimize it?
-
Dave.
I had some extensions unloaded........ load them and restarted SU and is working now...
Thanks.
-
There's no way in the world we could have helped you without knowing that.
I'm glad it's working now.

Hi Dave R,
My understanding from this exchange is that the problem was related to Victor Hugo's plugin folder, but is there anything I should do to make this plugin more robust?
