So here is the error message from the console:

Error: #<NoMethodError: undefined method best_picked' for nil:NilClass> (eval):108:in set_current_point'
(eval):83:in `onLButtonUp'

and here is a screenshot of my plugins folder.

I'm voluntarily ommitting to upload the .skp file as it is probably the same as JSPRO, a simple cylinder component and a simple rectangle component. Nothing else.

Ok, i installed the plugin, viewed the toolbar BUT, if i create 2 components and then select one of the boolean tool, when i try to select any of the 2 components, nothing happens. I cant even seem to be able to select the components, meaning they dont outline in blue. I have to unselect the boolean tool and try again. But nothing changes and it still doesnt do it.
Also i looked like it would work with 2 groups instead of components, meaning i can at least select the 2 groups but coolean is processing... forever with actually resulting in anything.

any tips?

Ok, again, very sorry.
I've found out on the pages that i didnt read.
Hehe.
View/tool palette/OSCoolean.

there i go...

Hi, i'm sorry, i havent read all pages for this topic but the prime and the last ones.

So i've put the oscar folder and the OSCoolean.rbs file in my sktechup 8 plugins folder, restarted the beast and i dont even see the boolean toolbar. Nothing.

Is it normal? does it work with sketchup 8?
