This is absolutely fantastic.
Just to be able to verify quickly will be so useful.

v2.0.1 - Added confirmation when choosing materials, now using .rbz install methodCheers
don't know why: version 2.0.0 is downloaded following the link
and when y try, the ruby box says

apart from that, it is a nice idea, wish it comes through

oh yeah... I'll be watching this one.

Sorry about this, I did upload the file but for some reason sourceforge did not pick it up as the latest version. I have manually overridden this now and the newest version should be available for download.

I tried again the link and yes, now it is the last version
I tried a few times and it worked as expected; sometimes it didn't though
once i got this error message:
"Error: #<NoMethodError: undefined method
[]' for nil:NilClass> C:/Archivos de programa/Google/Google SketchUp 8/Plugins/SketchStruct2/read.rb:231:inget_nodal_loads'

C:/Archivos de programa/Google/Google SketchUp 8/Plugins/SketchStruct2/read.rb:231"With another example, the program gave a result, but in the ruby box, it wrote
"no. joints: 4
no. bars: 3
no. restraints: 4
DOF: 8
Maxwell's number: 1
Errror, mechanism forming
no. degrees of freedom: 8"Obviously, there is still a lot of work to do to make it a usable tool, but i like very much having it in the sketchup environment

Hi
Just a couple of questions about how you created the structure.
When I run your file I get the same error, however, when I redraw the structure, the program runs fine.
Did you first draw your structure with SketchStruct installed?
and
Did you draw the structure manually, line by line?
Thanks
Tom

Yes to the first question
No to the second
I had it drawn automatically by another plugin i am working on, that makes a model of a scaffolding
From this model, i kept only the axis line and applied to it loads, supports, material and geometric values.
I didn't guess it would make a difference with a structure drawn from scratch

Ok, it looks like the two plugins are incompatible at the moment. SketchStruct uses a couple of minor functions for numbering the edges, this is done as the lines are drawn by the user.
This is a simple function which probably be included in your plugin to allow the two plugins to work together.
If you want more info on how the numbering works, I will be happy to help.

The plugin i am working on doesn't use any numbering for edges; it is probably done automatically by sketchup
It seems to me that it would be an enhancement for your plugin to be able to number edges of an existing drawing; this way the user could store models and re-use them
Anyway, this is how usual structural analysis softwares work
Thank you for your answer

I did attempt to achieve this with the automatic Sketchup numbering, however, I had problems as Sketchup does not save these consistently. i.e. the IDs would change between sessions after saving and loading.
Hopefully I can find a way to achieve this with the sketchup numbering. I will try to look for a way to include this in the next version.
